[Dan] Does this prove that the tales 203 00:09:54,667 --> 00:09:57,500 of the real life Dracula are actually true? 204 00:09:57,500 --> 00:10:00,708 - So this chance discovery in Tokat Castle 205 00:10:00,708 --> 00:10:02,875 may actually be the connection 206 00:10:02,875 --> 00:10:07,042 that we need of the dungeons and the terror experienced 207 00:10:07,042 --> 00:10:10,667 by Vlad the Impaler that led to the inspiration 208 00:10:10,667 --> 00:10:13,458 for Bram Stoker's Prince of Darkness. 209 00:10:13,458 --> 00:10:14,667 (suspenseful music) 210 00:10:14,667 --> 00:10:16,750 -

The age of exploration opened the world's eyes 215 00:10:29,875 --> 00:10:32,708 to just how vast the planet's oceans are. 216 00:10:32,708 --> 00:10:35,750 It also opened the door to many questions, 217 00:10:35,750 --> 00:10:37,958 like just how deep are those waters 218 00:10:38,917 --> 00:10:40,875 and what the heck is down there? 219 00:10:41,250 --> 00:10:43,167 (suspenseful music) 220 00:10:43,167 --> 00:10:47,958 - In 1875, the HMS Challenger is circumnavigating the globe 221 00:10:47,958 --> 00:10:51,125 in what was really the first great oceanographic expedition. 222 00:10:52,625 --> 00:10:55,042 - Pretty big adventure here. 223 00:10:55,042 --> 00:10:57,667 They're making the first charts of the ocean, if you will, 224 00:10:57,667 --> 00:10:59,292 and this is pretty important. 225 00:10:59,292 --> 00:11:01,875 So they roll up to the area called the Mariana Trench, 226 00:11:01,875 --> 00:11:06,750 and they drop a line, and it keeps going and going. 227 00:11:07,958 --> 00:11:09,875 -

They run out of rope 231 00:11:17,708 --> 00:11:19,917 and they can't actually get the exact depth. 232 00:11:21,708 --> 00:11:24,250 - And then 76 years later in 1951, 233 00:11:25,042 --> 00:11:27,417 the HMS Challenger II goes out. 234 00:11:27,417 --> 00:11:28,875 (suspenseful music) 235 00:11:28,875 --> 00:11:31,542 -

The Challenger II measures the Mariana Trench 239 00:11:39,875 --> 00:11:41,417 to be seven miles deep. 240 00:11:41,417 --> 00:11:44,292 It is officially the deepest part of the ocean. 241 00:11:45,542 --> 00:11:48,708 - It is also the deepest place on earth. 242 00:11:48,708 --> 00:11:50,083 (suspenseful music) 243 00:11:50,083 --> 00:11:51,917 - Let's put how deep this goes in perspective. 244 00:11:51,917 --> 00:11:55,292 It's as if you stacked 25 Empire State buildings 245 00:11:55,292 --> 00:11:58,417 on top of each other, that's how deep this is. 246 00:11:58,417 --> 00:11:59,875 - [Dan] That's pretty deep. 247 00:11:59,875 --> 00:12:02,958 So deep it makes curious explorers worldwide wonder, 248 00:12:03,750 --> 00:12:05,208 can anything live there? 249 00:12:08,208 --> 00:12:10,750 - The first ones to take the plunge are oceanographers, 250 00:12:10,750 --> 00:12:14,125 Jacques Piccard and Don Walsh in 1960. 251 00:12:14,125 --> 00:12:16,417 - And they get in this thing called the Bathysphere 252 00:12:16,417 --> 00:12:18,792 that descends underwater. 253 00:12:18,792 --> 00:12:20,125 (suspenseful music) 254 00:12:20,125 --> 00:12:22,208 - These guys get down to the bottom, 255 00:12:22,208 --> 00:12:24,875 they see what appears to be a barren landscape. 256 00:12:24,875 --> 00:12:26,083 The pressures are so great, 257 00:12:26,083 --> 00:12:29,042 there's no light to support photosynthesis. 258 00:12:29,042 --> 00:12:30,792 But when they look more closely, 259 00:12:30,792 --> 00:12:32,417 they see that there 260 00:12:32,417 --> 00:12:33,750 actually is life. 261 00:12:33,750 --> 00:12:36,833 (suspenseful music) 262 00:12:38,583 --> 00:12:40,708 -

[Dan] After a three hour ascent, 267 00:12:49,542 --> 00:12:52,000 the divers return to tell their tale, 268 00:12:52,000 --> 00:12:54,208 but now there are new questions. 269 00:12:54,208 --> 00:12:56,583 How many creatures are down there 270 00:12:56,583 --> 00:12:59,000 and how on earth do they survive? 271 00:12:59,000 --> 00:13:02,083 - Most of the life that we see in the ocean lives 272 00:13:02,083 --> 00:13:04,625 within the first 600 feet where the waters are warmer 273 00:13:04,625 --> 00:13:07,167 and there are kind of thriving ecosystems based on the sun. 274 00:13:07,167 --> 00:13:09,125 Below that, you enter the twilight zone 275 00:13:09,125 --> 00:13:11,042 where not a lot of light filters down 276 00:13:11,042 --> 00:13:12,833 and the ecosystems are kind of different. 277 00:13:12,833 --> 00:13:15,667 Below that, it's pitch black, 278 00:13:15,667 --> 00:13:17,208 (suspenseful music) 279 00:13:17,208 --> 00:13:20,208 and you get into alien worlds like something out of space, 280 00:13:20,208 --> 00:13:22,875 but they're happening right here below the ocean. 281 00:13:24,125 --> 00:13:26,417 - The creatures that live down there 282 00:13:26,417 --> 00:13:29,792 sound like creatures of darkness, vampire squid, 283 00:13:29,792 --> 00:13:32,708 zombie worms, goblin sharks. 284 00:13:32,708 --> 00:13:35,167 - One of my favorites is the dragon fish. 285 00:13:35,167 --> 00:13:36,708 And the coolest thing about them 286 00:13:36,708 --> 00:13:38,875 is that because it's so dark down there, 287 00:13:38,875 --> 00:13:40,417 they don't really use their eyes that much, 288 00:13:40,417 --> 00:13:43,250 but they've evolved to use bioluminescence. 289 00:13:43,250 --> 00:13:45,542 And so along their face and their jaw, 290 00:13:45,542 --> 00:13:47,583 they have these little spots 291 00:13:47,583 --> 00:13:48,792 that light up in different colors. 292 00:13:48,792 --> 00:13:50,875 And that actually attracts smaller fish, 293 00:13:50,875 --> 00:13:52,792 which when they approach the mouth of that animal, 294 00:13:52,792 --> 00:13:53,792 become a meal. 295 00:13:54,958 --> 00:13:56,375 (suspenseful music) 296 00:13:56,375 --> 00:13:58,750 - [Dan] To say the trench's temperatures fluctuate 297 00:13:58,750 --> 00:14:00,458 is an understatement. 298 00:14:00,458 --> 00:14:03,125 It can range anywhere from a chilly 34 299 00:14:03,125 --> 00:14:06,375 to a scalding 700 degrees Fahrenheit. 300 00:14:06,375 --> 00:14:07,375 - At those depths, 301 00:14:07,375 --> 00:14:10,000 there are also vents into the Earth's crust 302 00:14:10,000 --> 00:14:12,208 that release boiling hot water. 303 00:14:13,375 --> 00:14:15,708 And believe it or not, there are actually creatures 304 00:14:15,708 --> 00:14:17,000 that are also evolved 305 00:14:17,000 --> 00:14:19,875 to survive in those extreme conditions as well. 306 00:14:21,000 --> 00:14:23,042 - I'd say that the coolest thing about the trench 307 00:14:23,042 --> 00:14:26,417 is that it still remains largely unexplored. 308 00:14:26,417 --> 00:14:29,250 We've landed more people on the surface of the moon 309 00:14:29,250 --> 00:14:32,042 than we have in the depths of the Mariana Trench. 310 00:14:32,042 --> 00:14:34,708 So there is so much more there to find. 311 00:14:34,708 --> 00:14:36,500 There are more surprises to come, 312 00:14:37,792 --> 00:14:40,083 and more evil, deadly creatures to discover. 313 00:14:41,125 --> 00:14:43,542 (suspenseful music) 314 00:14:43,542 --> 00:14:46,917 - Just off the coast of Japan dwells a creature legend calls 315 00:14:46,917 --> 00:14:49,625 both evil and deadly, 316 00:14:49,625 --> 00:14:51,208 one that lies hidden 317 00:14:51,208 --> 00:14:54,542 deep beneath these treacherous waters. 318 00:14:54,542 --> 00:14:57,542 (suspenseful music) 319 00:14:59,875 --> 00:15:02,208 - There's this area of the Pacific Ocean 320 00:15:02,208 --> 00:15:04,208 that's between Japan, Taiwan, 321 00:15:04,208 --> 00:15:07,042 and Yap Island that could give the Bermuda Triangle 322 00:15:07,042 --> 00:15:08,208 a run for its money. 323 00:15:08,208 --> 00:15:10,208 It's called the Devil's Sea, 324 00:15:10,208 --> 00:15:13,375 and it has a ton of shipwrecks and disappearances, 325 00:15:14,458 --> 00:15:16,667 - [Dan] But according to Chinese legend, 326 00:15:16,667 --> 00:15:18,542 it's not the ocean that's to blame. 327 00:15:18,542 --> 00:15:21,208 - 3000 years ago, Chinese sailors tell stories 328 00:15:21,208 --> 00:15:25,042 of this huge undersea dragon pulling ships underwater 329 00:15:25,042 --> 00:15:26,375 and feasting on their crews, 330 00:15:26,375 --> 00:15:28,667 which is how the area gets its other name, 331 00:15:28,667 --> 00:15:30,125 the Dragon's Triangle. 332 00:15:31,250 --> 00:15:32,958 - [Dan] The Dragon's Triangle continues 333 00:15:32,958 --> 00:15:35,458 to claim countless victims over the years, 334 00:15:35,458 --> 00:15:39,667 including a hoard of fearsome 13th century warriors. 335 00:15:39,667 --> 00:15:42,042 - The conqueror, Kublai Khan, 336 00:15:42,042 --> 00:15:45,708 who is the grandson of Genghis Khan, 337 00:15:45,708 --> 00:15:48,542 decides to invade Japan. 338 00:15:48,542 --> 00:15:49,958 And according to records, 339 00:15:49,958 --> 00:15:54,375 lost 40,000 sailors to shipwrecks 340 00:15:54,375 --> 00:15:57,875 and determined to discontinue his planned invasion 341 00:15:57,875 --> 00:16:01,250 and to stay away from the Dragon's Triangle. 342 00:16:01,250 --> 00:16:03,583 The place is considered too dangerous. 343 00:16:05,542 --> 00:16:07,042 (suspenseful music) 344 00:16:07,042 --> 00:16:10,208 - [Dan] So what actually destroys Kahn's massive armies? 345 00:16:10,208 --> 00:16:13,875 Some say a typhoon, others say the gods, 346 00:16:13,875 --> 00:16:17,042 but Khan himself thinks something different. 347 00:16:17,042 --> 00:16:19,250 - Kublai Khan and and his advisors believed 348 00:16:19,250 --> 00:16:22,250 that their navy was swallowed by a sea dragon. 349 00:16:22,250 --> 00:16:24,583 Even one of history's most fearless warriors 350 00:16:24,583 --> 00:16:26,583 was rattled by these waters. 351 00:16:26,583 --> 00:16:28,083 (suspenseful music) 352 00:16:28,083 --> 00:16:30,667 -

He's pretty indignant about this, 366 00:17:07,875 --> 00:17:10,042 because when he mentions it, 367 00:17:10,042 --> 00:17:12,250 people think, "Have you been drinking a little bit? 368 00:17:12,250 --> 00:17:14,250 Or maybe you're mistaking it for a submarine." 369 00:17:14,250 --> 00:17:16,917 And he's like, "I know exactly what I saw. 370 00:17:16,917 --> 00:17:19,708 It's 150 feet long, this thing is a monster, 371 00:17:19,708 --> 00:17:22,250 it's a dragon in the water." 372 00:17:22,250 --> 00:17:23,583 (suspenseful music) 373 00:17:23,583 --> 00:17:25,375 - [Dan] The pilot's warning is brushed aside. 374 00:17:25,375 --> 00:17:28,083 But after nine more ships vanish in the Devil's Sea 375 00:17:28,083 --> 00:17:31,208 between 1946 and 1951, 376 00:17:31,208 --> 00:17:32,292 the Japanese government 377 00:17:32,292 --> 00:17:33,667 can no longer ignore 378 00:17:33,667 --> 00:17:35,125 that what's happening 379 00:17:35,125 --> 00:17:36,792 here could be fishy. 380 00:17:38,625 --> 00:17:42,250 -

In the early 2000s, geologist Heinrich Frank 408 00:18:53,125 --> 00:18:56,542 is driving in Novo Hamburgo in southern Brazil. 409 00:18:56,542 --> 00:18:59,125 And he passes a construction site, 410 00:18:59,125 --> 00:19:01,583 and something catches his eye, something weird. 411 00:19:02,958 --> 00:19:07,375 He sees this tunnel. It's a hole about 15 feet wide. 412 00:19:07,375 --> 00:19:10,000 This is a Friday afternoon and he has to keep driving. 413 00:19:10,000 --> 00:19:12,625 But Frank thinks about this all weekend. 414 00:19:13,625 --> 00:19:14,292 I mean, what is it? 415 00:19:14,292 --> 00:19:15,708 Is it a tunnel? 416 00:19:15,708 --> 00:19:16,958 Who made it? 417 00:19:16,958 --> 00:19:17,875 Where does it go? 418 00:19:17,875 --> 00:19:18,833 Why is it there? 419 00:19:20,208 --> 00:19:21,750 - He can't stop thinking about it. 420 00:19:21,750 --> 00:19:22,583 So a few weeks later, 421 00:19:22,792 --> 00:19:23,833 he goes back to the 422 00:19:23,833 --> 00:19:25,375 site to investigate. 423 00:19:25,375 --> 00:19:28,167 He goes up to this tunnel that is leading underground 424 00:19:28,167 --> 00:19:33,208 and he starts walking into this giant 15 foot hole. 425 00:19:34,250 --> 00:19:35,417 - And right away he notices something weird. 426 00:19:35,417 --> 00:19:37,083 Remember, he's a geologist, 427 00:19:37,083 --> 00:19:39,750 he knows that earth shaped by water 428 00:19:39,750 --> 00:19:42,958 is not gonna create a perfectly round opening. 429 00:19:42,958 --> 00:19:45,000 So this is an odd thing. 430 00:19:45,000 --> 00:19:47,750 - As he walks into this tunnel, the deeper he gets, 431 00:19:47,750 --> 00:19:49,125 he looks up at the ceiling, 432 00:19:49,125 --> 00:19:53,042 and he's noticing these giant claw marks. 433 00:19:53,042 --> 00:19:54,375 - [Dan] Even as a geologist, 434 00:19:54,375 --> 00:19:57,208 Frank now understands the chilling reality. 435 00:19:57,208 --> 00:20:00,208 He's standing in the home of something very big 436 00:20:00,208 --> 00:20:01,708 and very deadly. 437 00:20:01,708 --> 00:20:04,542 -
