Could it be much more? 9 00:00:35,050 --> 00:00:38,430 Is a massive creature actually lurking in the depths? 10 00:00:39,610 --> 00:00:46,210 To find out, we'll compare decades of encounters across northern Europe, and 11 00:00:46,210 --> 00:00:51,010 modern science to create a brand new profile of the beast, with help from the 12 00:00:51,010 --> 00:00:52,670 world's top aquatic experts. 13 00:00:55,110 --> 00:00:56,690 What might we discover? 14 00:00:57,310 --> 00:01:00,270 Could Nessie possibly exist in some form? 15 00:01:01,230 --> 00:01:03,830 Could it even be a new, never -before -seen species? 16 00:01:06,090 --> 00:01:07,090 No! 17 00:01:09,490 --> 00:01:15,270 And if so, could we potentially find it and have an up -close encounter of our 18 00:01:15,270 --> 00:01:16,270 own? 19 00:01:20,790 --> 00:01:26,550 Tonight, we dive deep in search of the Loch Ness Monster. 20 00:01:27,350 --> 00:01:30,250 Oh, there's the bubbles! There's the bubbles. He's getting ready to come up. 21 00:01:39,910 --> 00:01:41,710 You've probably heard this one before. 22 00:01:42,390 --> 00:01:46,330 If a tree falls in the woods and no one is around to hear it, does it make a 23 00:01:46,330 --> 00:01:47,330 sound? 24 00:01:47,830 --> 00:01:48,830 What about this? 25 00:01:49,610 --> 00:01:54,310 If a monstrous creature swims across the surface of a Scottish loch and no one 26 00:01:54,310 --> 00:01:56,990 takes a picture, was it ever really there? 27 00:01:58,110 --> 00:02:04,530 For over 1 ,400 years, according to thousands of eyewitnesses, the answer is 28 00:02:04,530 --> 00:02:05,530 yes. 29 00:02:06,000 --> 00:02:10,780 All of them saw something emerge from the depths of Loch Ness. 30 00:02:11,280 --> 00:02:14,180 The question is, what was it? 31 00:02:15,160 --> 00:02:18,100 Whatever it is, it's certainly camera shy. 32 00:02:18,360 --> 00:02:21,460 But that doesn't mean that Nessie can't be identified. 33 00:02:21,860 --> 00:02:26,380 In fact, we actually have a large pool of information to draw from. 34 00:02:26,640 --> 00:02:33,020 We have first -person encounters, recorded histories, and even some 35 00:02:33,020 --> 00:02:34,020 video. 36 00:02:34,190 --> 00:02:38,870 We have known species with similar characteristics that we can study for 37 00:02:38,870 --> 00:02:40,370 to Nessie's behavior. 38 00:02:42,250 --> 00:02:47,730 Add it all up, and perhaps we can build a profile of the monster to find out 39 00:02:47,730 --> 00:02:51,330 once and for all if the legend could possibly be true. 40 00:02:53,170 --> 00:02:59,970 With that goal in mind, let's start with a man who says he's actually seen 41 00:02:59,970 --> 00:03:00,970 the beast. 42 00:03:06,620 --> 00:03:11,320 Retired engineer Gordon Holmes is one of the few people who claims to have 43 00:03:11,320 --> 00:03:13,240 captured the Loch Ness Monster on camera. 44 00:03:15,800 --> 00:03:20,820 He's taking us the exact spot at the water's edge where his life changed 45 00:03:20,820 --> 00:03:21,820 forever. 46 00:03:22,220 --> 00:03:28,500 I saw the monster at 10 minutes to 10 on the 26th of May 2007. 47 00:03:29,660 --> 00:03:33,320 During the morning I'd been doing hydrophonic research on the Loch. 48 00:03:33,900 --> 00:03:39,520 At the evening, I decided to go up to the lay -by, which had a good commanding 49 00:03:39,520 --> 00:03:42,280 view of the lock, about 70 foot above the surface. 50 00:03:43,240 --> 00:03:49,080 This was my fourth visit up to the lock, and I hadn't actually got anything 51 00:03:49,080 --> 00:03:51,900 concrete, evidence of something mysterious. 52 00:03:56,480 --> 00:04:01,640 Despite years spent waiting, Gordon remained determined to see the Loch Ness 53 00:04:01,640 --> 00:04:02,640 Monster. 54 00:04:03,400 --> 00:04:07,320 And on this day, his persistence finally paid off. 55 00:04:08,840 --> 00:04:12,640 I'd been there for a few hours and then suddenly I saw something coming towards 56 00:04:12,640 --> 00:04:13,640 me. 57 00:04:14,100 --> 00:04:18,760 I immediately reached over the back seat and grabbed my camcorder. 58 00:04:20,000 --> 00:04:24,980 I dashed out, slammed the door, and then suddenly I realised that's not what 59 00:04:24,980 --> 00:04:30,360 you're supposed to do. I've read that if you see a potential monster... 60 00:04:30,800 --> 00:04:35,900 Don't slam the door, because that'll frighten it. So I then ran down to the 61 00:04:35,900 --> 00:04:40,220 of the lay -by and realised it disappeared. Where's it gone? 62 00:04:41,960 --> 00:04:47,580 And then suddenly I saw it over to the right and immediately I got the 63 00:04:47,580 --> 00:04:50,260 and zoomed into its position. 64 00:04:51,460 --> 00:04:56,000 For the next two and a half minutes, I was privileged to one of the most 65 00:04:56,000 --> 00:04:57,300 sights I've ever seen. 66 00:05:05,040 --> 00:05:09,440 As you can see from Gordon's footage, there is most definitely some type of 67 00:05:09,440 --> 00:05:11,440 large animal swimming across the loch. 68 00:05:17,280 --> 00:05:18,800 But what could it be? 69 00:05:19,860 --> 00:05:24,980 This thing was like bubbling along the waves. At no point did it break through 70 00:05:24,980 --> 00:05:27,580 the surface of the streamlined water flow. 71 00:05:30,560 --> 00:05:33,760 The creature appears to be moving in a serpentine fashion. 72 00:05:34,400 --> 00:05:36,060 almost slithering through the water. 73 00:05:38,220 --> 00:05:43,440 Based on the species known to inhabit Loch Ness, one might conclude that this 74 00:05:43,440 --> 00:05:44,440 an eel. 75 00:05:46,420 --> 00:05:51,540 But when you analyze the video more carefully, the eel theory seems 76 00:05:53,100 --> 00:05:57,620 I read somewhere that if you ever get a sighting of something like this, you 77 00:05:57,620 --> 00:05:59,040 should zoom in and out. 78 00:05:59,870 --> 00:06:05,830 so that the people that analyze the footage can always then estimate the 79 00:06:05,830 --> 00:06:07,290 whatever the creature was. 80 00:06:07,510 --> 00:06:12,910 And at the same time, you can prove it's not like a fake because she's seen it 81 00:06:12,910 --> 00:06:13,910 in context. 82 00:06:14,910 --> 00:06:21,870 In context, the animal appears to be at least 15 feet long, much larger than any 83 00:06:21,870 --> 00:06:27,490 freshwater eel species, and therefore potentially something completely 84 00:06:28,940 --> 00:06:33,040 It was certainly going at speed into the waves. It wasn't some sort of log. 85 00:06:33,520 --> 00:06:38,720 This was a creature that had energy, it had power. It was thrusting through the 86 00:06:38,720 --> 00:06:39,720 waves. 87 00:06:40,800 --> 00:06:45,300 In addition to the creature's length, experts were able to determine that it 88 00:06:45,300 --> 00:06:47,980 moving at a top speed of six miles per hour. 89 00:06:50,180 --> 00:06:56,080 This is probably the best footage up to this time of the so -called Loch Ness 90 00:06:56,080 --> 00:06:57,080 Monster. 91 00:06:57,100 --> 00:07:01,540 I realised this was a turning point in the history of the Loch Ness Monster. 92 00:07:05,600 --> 00:07:07,820 But Gordon is still unsatisfied. 93 00:07:08,420 --> 00:07:11,600 He hopes to eventually have another encounter with the creature. 94 00:07:11,820 --> 00:07:15,800 And this time, he plans to be ready with even better equipment. 95 00:07:18,060 --> 00:07:24,960 If money was no object, I'd have my own research boat with underwater robotic 96 00:07:24,960 --> 00:07:25,960 vehicles. 97 00:07:28,499 --> 00:07:32,980 Meanwhile, Gordon has purchased a hydrophone to pick up sound signatures 98 00:07:32,980 --> 00:07:39,640 water, a sky camera carried by helium balloons as a makeshift drone, and a 99 00:07:39,640 --> 00:07:40,640 magnetometer. 100 00:07:42,240 --> 00:07:49,160 In order to understand Nessie's environment, should she exist, you need 101 00:07:49,160 --> 00:07:53,300 to delve into all the parameters possible, the variables and the 102 00:07:54,830 --> 00:07:58,270 But science alone may not be enough to catch a second glimpse. 103 00:07:59,510 --> 00:08:02,570 Gordon believes it will take some luck as well. 104 00:08:04,250 --> 00:08:09,050 I've witnessed several times tourists that come to the side of the lock and 105 00:08:09,050 --> 00:08:13,090 can tell they're praying to see something, to see the monster. 106 00:08:13,590 --> 00:08:19,290 And I, by chance, being in the right place at the right time, just happened 107 00:08:19,290 --> 00:08:22,330 capture on film something remarkable. 108 00:08:29,040 --> 00:08:33,299 But of course Gordon Holmes' sighting is only a small part of a much longer 109 00:08:33,299 --> 00:08:34,980 history for this unknown species. 110 00:08:38,820 --> 00:08:43,860 If we want to solve the mystery of the Loch Ness Monster, we'll have to go back 111 00:08:43,860 --> 00:08:44,860 a whole lot further. 112 00:08:46,080 --> 00:08:51,720 The Loch Ness Monster was first written about in 565 A .D. in the story of St. 113 00:08:51,860 --> 00:08:56,700 Columba, an Irish monk who was traveling along the banks of the River Ness. 114 00:08:57,050 --> 00:08:58,810 when he happened upon a man's funeral. 115 00:09:01,010 --> 00:09:05,890 The townspeople explained that the man had been swimming when he was attacked 116 00:09:05,890 --> 00:09:07,690 and killed by a water beast. 117 00:09:12,410 --> 00:09:17,150 At that time, people most likely believed this water beast was a dragon. 118 00:09:18,870 --> 00:09:23,070 But as the centuries passed, people stopped believing in dragons. 119 00:09:25,360 --> 00:09:26,800 Yet the sightings continued. 120 00:09:27,680 --> 00:09:31,420 All in the same area, and all eerily similar. 121 00:09:31,920 --> 00:09:36,980 A massive unidentified animal churning up the water as it swims across the 122 00:09:39,480 --> 00:09:41,420 This was no mythical creature. 123 00:09:41,880 --> 00:09:43,280 This was no dragon. 124 00:09:44,200 --> 00:09:48,100 Witnesses confirmed that whatever it was, it was very real. 125 00:09:52,319 --> 00:09:55,420 Local pubs were full of stories of the mysterious beast. 126 00:09:56,720 --> 00:10:02,920 But the legend of the Loch Ness Monster wasn't taken seriously until 1933, when 127 00:10:02,920 --> 00:10:07,160 a reputable law enforcement officer, Loch Ness water bailiff Alex Campbell, 128 00:10:07,380 --> 00:10:09,720 spotted the monster multiple times. 129 00:10:10,980 --> 00:10:15,220 What's the most you've ever seen of it at any one sighting? The best view I 130 00:10:15,220 --> 00:10:19,260 had was the very first thing. I saw the head, the neck, and the huge body, which 131 00:10:19,260 --> 00:10:21,020 I'd say was about 30 feet long. 132 00:10:21,420 --> 00:10:23,520 And the skin was exactly like that of an elephant. 133 00:10:23,780 --> 00:10:24,920 Wrinkly, tough -looking. 134 00:10:25,140 --> 00:10:28,960 Is it not possible, Mr. Campbell, that you're mistaken in this? Not at all. 135 00:10:29,980 --> 00:10:35,100 When all of this evidence is combined, it seems that there actually might be a 136 00:10:35,100 --> 00:10:37,520 large, unidentified species in Loch Ness. 137 00:10:39,520 --> 00:10:44,820 Monster or not, we can start to use this information to build a profile and find 138 00:10:44,820 --> 00:10:45,820 out for ourselves. 139 00:10:48,040 --> 00:10:53,240 Campbell described a beast 30 feet from end to end, with a four -foot -high body 140 00:10:53,240 --> 00:10:56,460 and a wavy, narrow neck stretching 12 feet long. 141 00:10:58,200 --> 00:11:03,360 After years of vague descriptions and tall tales, this was the first highly 142 00:11:03,360 --> 00:11:08,160 detailed account of the alleged creature that would soon be dubbed the Loch Ness 143 00:11:08,160 --> 00:11:09,160 Monster. 144 00:11:10,000 --> 00:11:15,420 And just a few months later, an even more spectacular bombshell fueled Nessie 145 00:11:15,420 --> 00:11:16,900 fever around the world. 146 00:11:19,050 --> 00:11:26,050 On April 21st, 1934, London's Daily Mail published what it claimed 147 00:11:26,050 --> 00:11:30,650 was the first photograph ever taken of the Loch Ness Monster. 148 00:11:39,150 --> 00:11:44,090 Sightings of Scotland's famed Loch Ness Monster have been reported since the 6th 149 00:11:44,090 --> 00:11:45,090 century. 150 00:11:46,060 --> 00:11:52,380 But it wasn't until April 21st, 1934, that the search for the creature truly 151 00:11:52,380 --> 00:11:53,380 took off. 152 00:11:54,160 --> 00:11:56,280 And it was all thanks to this. 153 00:12:00,020 --> 00:12:04,080 Known as the Surgeon's Photograph, the picture was snapped by London 154 00:12:04,080 --> 00:12:10,780 gynecologist Robert Kenneth Wilson while out for a lakeside walk and published 155 00:12:10,780 --> 00:12:12,700 in London's Daily Mail newspaper. 156 00:12:16,200 --> 00:12:21,360 The image appears to show a silhouetted figure with a long, slender neck, a 157 00:12:21,360 --> 00:12:25,520 small head, and a large body that's obscured by the waterline. 158 00:12:30,900 --> 00:12:35,880 Immediately after the photo was published, the British public began 159 00:12:35,880 --> 00:12:38,000 on the nature of this mysterious beast. 160 00:12:39,160 --> 00:12:41,740 What could this photo possibly depict? 161 00:12:44,520 --> 00:12:47,700 Some suggested it was the dorsal fin of a dolphin or whale. 162 00:12:49,460 --> 00:12:53,060 Others thought it might be a submerged elephant raising its trunk to breathe. 163 00:12:54,820 --> 00:12:59,520 A circus had recently visited the area, giving more strength to this theory. 164 00:13:01,320 --> 00:13:06,360 But the most popular belief may also have been the most far -fetched. 165 00:13:08,060 --> 00:13:12,220 Many thought this was a creature that had been extinct for millions of years. 166 00:13:13,550 --> 00:13:17,630 It's a theory that continued for decades after the photo was first published. 167 00:13:18,770 --> 00:13:21,690 So what particular species do you think it is? 168 00:13:22,090 --> 00:13:27,390 The evidence, as I interpret it, all fits, and I know this is a fantastic 169 00:13:27,390 --> 00:13:29,850 statement, but this all fits plesiosaur. 170 00:13:32,950 --> 00:13:37,190 Could it be possible that the plesiosaur, thought to have died out 171 00:13:37,190 --> 00:13:42,170 dinosaurs, had actually survived, only to end up here in Scotland? 172 00:13:43,530 --> 00:13:47,410 Before you decide for yourself, there's one thing you should know. 173 00:13:48,330 --> 00:13:52,410 This first iconic image was a Hulk. 174 00:13:57,330 --> 00:14:03,730 In 1994, 60 years after it was first published in the Daily Mail, the true 175 00:14:03,730 --> 00:14:05,330 of the photograph came to light. 176 00:14:05,810 --> 00:14:10,810 The newspaper hired big game hunter Marmaduke Wetherall to find evidence of 177 00:14:10,810 --> 00:14:16,590 monster. Instead, he created a model of a beast with a long neck and attached it 178 00:14:16,590 --> 00:14:17,590 to a toy submarine. 179 00:14:18,050 --> 00:14:23,130 He then chose a trustworthy physician, Dr. R. Kenneth Wilson, to deliver the 180 00:14:23,130 --> 00:14:24,930 photograph of his creation. 181 00:14:25,250 --> 00:14:27,450 And the rest is history. 182 00:14:28,150 --> 00:14:33,230 But that one hoax doesn't explain countless other sightings and more 183 00:14:33,230 --> 00:14:36,810 photo and video evidence that has yet to be disproven. 184 00:14:38,110 --> 00:14:41,710 In 1955, Peter McNabb captured this image. 185 00:14:42,090 --> 00:14:47,610 In the 1970s, an American scientist shot this underwater photograph depicting a 186 00:14:47,610 --> 00:14:49,030 30 -foot -long flipper. 187 00:14:49,310 --> 00:14:54,310 And of course, we have the 2007 footage from Gordon Holmes. 188 00:14:56,490 --> 00:15:00,690 None of these sightings provide definitive proof of the Loch Ness 189 00:15:00,690 --> 00:15:01,690 existence. 190 00:15:02,150 --> 00:15:06,970 But they do suggest the possibility that some large species might be lurking 191 00:15:06,970 --> 00:15:07,970 there. 192 00:15:09,770 --> 00:15:12,630 The question is, what species could it be? 193 00:15:13,390 --> 00:15:16,590 Can we build a profile to potentially identify it? 194 00:15:17,770 --> 00:15:22,930 First of all, Gordon Holmes described an eel -like aspect to the front of the 195 00:15:22,930 --> 00:15:23,930 creature. 196 00:15:25,010 --> 00:15:29,290 His video shows that it can hold itself up near the surface for an extended 197 00:15:29,290 --> 00:15:33,350 period, with a cruising speed of 6 miles per hour. 198 00:15:35,010 --> 00:15:39,660 Therefore, Something below the water is propelling it upwards as well as 199 00:15:39,660 --> 00:15:40,660 forwards. 200 00:15:41,700 --> 00:15:44,440 Most likely the flippers seen in this image. 201 00:15:49,600 --> 00:15:53,580 Unfortunately, this small amount of visual evidence can't tell us much else. 202 00:15:55,000 --> 00:15:59,960 But we do know one more key piece of information that's crucial to our 203 00:16:02,120 --> 00:16:04,420 We know that if this species exists, 204 00:16:05,180 --> 00:16:10,420 It has managed to elude capture for more than 1 ,400 years in these Scottish 205 00:16:10,420 --> 00:16:11,420 waterways. 206 00:16:17,320 --> 00:16:22,500 Local water bailiff Chris Conroy thinks he knows how an animal could manage to 207 00:16:22,500 --> 00:16:25,580 stay undetected for so long in these unique conditions. 208 00:16:32,030 --> 00:16:36,630 Loch Ness contains as much water as all the rivers and lakes in England and 209 00:16:36,630 --> 00:16:37,449 Wales combined. 210 00:16:37,450 --> 00:16:40,870 It's the largest water body in the whole of the UK. It's absolutely massive. 211 00:16:42,830 --> 00:16:45,630 It's really hard to comprehend just how big this loch is. 212 00:16:45,910 --> 00:16:50,050 It runs from east to west. It's a total of about 23 miles long. 213 00:16:50,270 --> 00:16:54,470 It averages about a mile wide and it's about 750 feet deep. 214 00:16:55,170 --> 00:16:59,730 If you look at the shape of the loch, you've got these really steep sides. 215 00:17:00,940 --> 00:17:04,680 The tops of the hills here are about the same height up as the depth of the 216 00:17:04,680 --> 00:17:09,079 loch, and they go straight down on the edges, very, very steep, and as you hit 217 00:17:09,079 --> 00:17:12,980 the bottom of the loch, it becomes very flat, very full of sediment, and you get 218 00:17:12,980 --> 00:17:14,060 this sort of bathtub shape. 219 00:17:18,099 --> 00:17:21,920 In other words, there's plenty of room in Loch Ness to hide. 220 00:17:23,040 --> 00:17:27,440 And even if someone were to search beneath the water, they wouldn't survive 221 00:17:27,440 --> 00:17:28,440 long. 222 00:17:30,090 --> 00:17:34,930 Loch Ness features a phenomenon called a thermocline, which causes deadly 223 00:17:34,930 --> 00:17:36,690 conditions as you dive down. 224 00:17:40,390 --> 00:17:42,310 It's a stratification of temperature. 225 00:17:42,510 --> 00:17:46,870 So as you go down into the water column, a relatively short distance, you 226 00:17:46,870 --> 00:17:50,330 suddenly hit a temperature barrier and there'll be a significant change in 227 00:17:50,330 --> 00:17:52,830 temperature up to maybe around 10 degrees. 228 00:17:53,530 --> 00:17:59,210 This affects the chemistry underneath. So if you are to go underneath... 229 00:17:59,560 --> 00:18:01,820 that barrier, you'll suddenly become very, very cold. 230 00:18:03,660 --> 00:18:07,700 Even at the locked surface, the average water temperature is 42 degrees 231 00:18:07,700 --> 00:18:08,700 Fahrenheit. 232 00:18:10,000 --> 00:18:14,760 Beneath the thermocline, without the protection of a modern dry suit, a diver 233 00:18:14,760 --> 00:18:16,660 could drown in under six minutes. 234 00:18:19,440 --> 00:18:23,880 And those freezing temperatures are paired with near blackout conditions. 235 00:18:29,070 --> 00:18:32,910 it's an absolutely perfect place for something to hide it's it's very 236 00:18:32,910 --> 00:18:37,830 to see anything the water is very peaty as we call it now the peat is basically 237 00:18:37,830 --> 00:18:42,910 organic matter that's breaking down it's washed into the rivers and that comes 238 00:18:42,910 --> 00:18:49,770 flows into the loch and you end up with this really dark tea colored water okay 239 00:18:49,770 --> 00:18:52,390 let's do a little bit of a test here just to show you what the water's like 240 00:18:52,390 --> 00:18:58,150 here so i've got a standard whiskey glass we just pop it in the water here 241 00:18:58,150 --> 00:19:04,830 in the top you can see how clear it is but don't let that fool you because 242 00:19:04,830 --> 00:19:09,390 as you get deeper down you'll see the color change if you were to go just a 243 00:19:09,390 --> 00:19:13,530 little bit further down or towards the bottom it would start to look more like 244 00:19:13,530 --> 00:19:19,910 this you can see it's much more tea -like in color and it's all the organic 245 00:19:19,910 --> 00:19:24,250 matter that's broken down leaves and other plant material that's washed down 246 00:19:24,250 --> 00:19:25,890 rivers and creates this really dark color 247 00:19:30,700 --> 00:19:35,840 While that unique watercolor makes the alleged monster hard to find, it also 248 00:19:35,840 --> 00:19:38,700 gives us a significant clue to its possible appearance. 249 00:19:40,660 --> 00:19:45,620 If it can stay undetected in these conditions, it must have a natural 250 00:19:45,620 --> 00:19:46,620 camouflage. 251 00:19:50,600 --> 00:19:54,960 Nessie's skin has often been portrayed as flat gray or bright green. 252 00:19:55,900 --> 00:19:57,240 But in fact... 253 00:19:57,550 --> 00:20:02,770 it much more likely matches the tea -like appearance of the surrounding 254 00:20:02,770 --> 00:20:03,970 mottled brownish color. 255 00:20:07,650 --> 00:20:13,010 But if we hope to identify the Loch Ness Monster, knowing its color won't be 256 00:20:13,010 --> 00:20:14,010 enough. 257 00:20:19,030 --> 00:20:25,690 At 750 feet deep and 23 miles long, near blackout conditions 258 00:20:25,690 --> 00:20:26,730 below the water, 259 00:20:27,850 --> 00:20:30,630 and average surface temperatures of 42 degrees, 260 00:20:31,410 --> 00:20:36,370 Loch Ness is an incredibly challenging place to track down an unknown species. 261 00:20:38,210 --> 00:20:43,710 But if we hope to identify the Loch Ness monster, at some point, we'll have to 262 00:20:43,710 --> 00:20:44,710 dive in. 263 00:20:49,010 --> 00:20:54,550 Fortunately, before we do, footage from several underwater cameras can give us a 264 00:20:54,550 --> 00:20:56,850 preview of what lives beneath the surface. 265 00:21:06,640 --> 00:21:12,200 A surprising number of species thrive in the loch, even at its maximum depth of 266 00:21:12,200 --> 00:21:13,420 750 feet. 267 00:21:14,020 --> 00:21:19,860 We've got trout, brown trout, we've got arctic char, we've got eels, we've got 268 00:21:19,860 --> 00:21:24,660 lamprey species, and then we've got other species which have been seen here, 269 00:21:24,740 --> 00:21:29,180 which include the records of sturgeon, northern pike, and perch. 270 00:21:29,440 --> 00:21:33,600 In addition to the fish, mammals follow the fish into the river, and we 271 00:21:33,600 --> 00:21:34,600 regularly get seals. 272 00:21:35,070 --> 00:21:38,370 living in Loch Ness, particularly the common or harbour seal, and it's an easy 273 00:21:38,370 --> 00:21:39,370 food source for them. 274 00:21:41,690 --> 00:21:44,630 And could it also be a food source for something else? 275 00:21:46,190 --> 00:21:52,810 Could the loch's population of trout, arctic char, pike, eels and lamprey 276 00:21:52,810 --> 00:21:57,050 possibly be enough to feed a large predator all year round? 277 00:22:00,450 --> 00:22:02,530 Sounds like there's a lot, but actually... 278 00:22:03,070 --> 00:22:08,130 Given the depth and the size of it, there isn't as much as a density of food 279 00:22:08,130 --> 00:22:12,010 you might think.

It was right there. 467 00:36:55,860 --> 00:37:00,760 Since then, Matt and his team have caught and tagged more than 700 468 00:37:00,760 --> 00:37:05,020 sturgeons. using acoustic receivers to track their migratory movements. 469 00:37:07,960 --> 00:37:09,140 So that's a fish. 470 00:37:09,960 --> 00:37:15,560 If he can catch one today, it could provide critical new information to help 471 00:37:15,560 --> 00:37:17,840 identify the creature hiding in Loch Ness. 472 00:37:18,200 --> 00:37:20,980 Oh, there's the bubbles. There's the bubbles. He's getting ready to come up. 473 00:37:28,520 --> 00:37:33,320 As we continue to build our profile of the Loch Ness Monster, we've zeroed in 474 00:37:33,320 --> 00:37:34,480 a compelling new theory. 475 00:37:36,920 --> 00:37:42,060 What if the creature is a migratory animal with a range that stretches far 476 00:37:42,060 --> 00:37:43,140 beyond the loch? 477 00:37:45,840 --> 00:37:52,560 If that's the case, another large migratory species, the Atlantic 478 00:37:52,560 --> 00:37:54,360 hold clues to Nessie's behavior. 479 00:37:58,690 --> 00:38:00,410 We're getting ready to pull in the first net. 480 00:38:00,990 --> 00:38:04,010 There's the bubble. There's the bubble. He's getting ready to come up. He's 481 00:38:04,010 --> 00:38:05,370 getting ready to come up. Yeah, he's pulling. 482 00:38:06,170 --> 00:38:07,170 There he is. 483 00:38:10,310 --> 00:38:11,570 Okay, hold on. 484 00:38:12,390 --> 00:38:13,390 Yeah, he's pulling. 485 00:38:17,490 --> 00:38:18,670 All right, we're done. 486 00:38:21,250 --> 00:38:25,730 Despite this fish's impressive length, it's only a medium -sized specimen. 487 00:38:26,890 --> 00:38:28,870 We're just going to measure it down the length of its belly. 488 00:38:29,190 --> 00:38:30,190 Okay. 489 00:38:31,150 --> 00:38:37,490 This fish is just over 7 feet long, but historically there are records of them 490 00:38:37,490 --> 00:38:42,630 twice as big as this, and there's unofficial records of 18 feet long. 491 00:38:45,050 --> 00:38:48,090 These sturgeon also have incredible lifespans. 492 00:38:48,410 --> 00:38:51,530 The biggest ones can live over 100 years. 493 00:38:52,650 --> 00:38:58,230 For our purposes, as we try to identify the Loch Ness Monster, we need only ask 494 00:38:58,230 --> 00:38:59,230 one question. 495 00:38:59,870 --> 00:39:04,510 What does it take for a massive North Sea predator like the sturgeon, and like 496 00:39:04,510 --> 00:39:07,170 Nessie, to survive for so long? 497 00:39:10,910 --> 00:39:16,330 One possible explanation is the sturgeon's natural built -in armor 498 00:39:17,230 --> 00:39:19,850 This is the dorsal line of scoots right here. 499 00:39:20,410 --> 00:39:24,210 These are actually bone. It's a form of calcium phosphate, which is just like 500 00:39:24,210 --> 00:39:27,650 our bones. And it's actually wrapped all around the fish. It's got them on the 501 00:39:27,650 --> 00:39:31,190 side and it has them on the belly. This is pretty much a suit of armor all 502 00:39:31,190 --> 00:39:32,190 around it. 503 00:39:33,470 --> 00:39:38,170 These bony plates, called scutes, have given the sturgeon the ability to 504 00:39:38,170 --> 00:39:43,670 outgrow, outlive, and outsurvive almost every other species in the North Sea. 505 00:39:45,840 --> 00:39:48,080 They are some of the ultimate survivors. 506 00:39:48,440 --> 00:39:53,740 240 million years ago is the upper end of when these fish started to come 507 00:39:53,740 --> 00:39:57,140 around. And these fish have persisted that whole time. 508 00:39:57,680 --> 00:40:02,920 The fact that this fish here was dodging dinosaurs, I think that's pretty 509 00:40:02,920 --> 00:40:03,920 awesome. 510 00:40:04,420 --> 00:40:09,260 According to Matt, armored plates much like the sturgeon's could be a perfect 511 00:40:09,260 --> 00:40:13,480 explanation for one of Nessie's key features as described by alleged 512 00:40:13,480 --> 00:40:14,480 eyewitnesses. 513 00:40:17,260 --> 00:40:22,820 A lot of the sightings in Loch Ness are of, like, humps on the side. 514 00:40:23,720 --> 00:40:27,840 Those could potentially be scoots, especially on a big sturgeon when the 515 00:40:27,840 --> 00:40:30,200 will be really big and the ridge will be really tall. 516 00:40:34,720 --> 00:40:39,780 Is it possible that the Loch Ness monster's famous humps along its back 517 00:40:39,780 --> 00:40:44,040 humps at all, but instead are a series of bony armored plates? 518 00:40:45,290 --> 00:40:49,610 The Atlantic sturgeon may just have provided an important clue in our 519 00:40:52,890 --> 00:40:58,110 And other members of the sturgeon family tree could offer even more useful 520 00:40:58,110 --> 00:40:59,110 information. 521 00:41:00,590 --> 00:41:05,450 Atlantic sturgeon are really just bottom feeders eating bugs, but there's a lot 522 00:41:05,450 --> 00:41:09,590 of other sturgeon species, like the belugas and the white sturgeon, that 523 00:41:09,590 --> 00:41:12,370 actually do actively prey on fish. 524 00:41:12,590 --> 00:41:14,510 And those sturgeon actually get really big. 525 00:41:15,500 --> 00:41:21,120 As you can see in this photo from 1903, beluga sturgeon have been documented at 526 00:41:21,120 --> 00:41:22,420 nearly 30 feet long. 527 00:41:24,520 --> 00:41:29,820 Considering their massive size, body shape, and ability to hide and survive 528 00:41:29,820 --> 00:41:35,200 cold, dark water, the sturgeon is one of the closest species we can study to 529 00:41:35,200 --> 00:41:38,340 determine the behavior and appearance of the Loch Ness Monster. 530 00:41:39,400 --> 00:41:44,240 Despite their 30 -foot length, beluga sturgeon can freely move between 531 00:41:44,240 --> 00:41:47,160 freshwater and saltwater while hunting their prey. 532 00:41:47,560 --> 00:41:52,340 And sturgeon have been found in both Loch Ness and in Sweden. 533 00:41:56,460 --> 00:41:57,800 Is that our answer? 534 00:41:58,840 --> 00:42:01,960 Could the monster simply be an overgrown sturgeon? 535 00:42:02,720 --> 00:42:08,180 As we're about to find out, the mystery is still far from being solved. 536 00:42:11,470 --> 00:42:16,590 Next time, there's a chance we've had physical evidence of the Loch Ness 537 00:42:16,590 --> 00:42:17,590 for centuries. 538 00:42:18,130 --> 00:42:19,130 Go! 539 00:42:19,930 --> 00:42:25,370 And if that's the case, then we may know exactly where to look for our own 540 00:42:25,370 --> 00:42:26,750 encounter with the beast. 48193
