ALIEN SHARKS: Return to the Abyss: A program dedicated to exploring the deepest depths of the ocean in hopes of not only viewing the rarest shark species out there, but also discovering entirely new species of sharks. This is absolutely amazing - how is it that we are STILL discovering new creatures? The ocean floor is one of the least explored and understood parts of the wide world - less is known about our oceans and what is out there than space. Think about that for a minute. We live on earth and still know less about it than we do about what's NOT. ON. EARTH. FREAKY.
The expedition, set 1200 miles off the tip of Africa to plumb the depths of the Southwest Indian Ridge in the Indian Ocean, was searching for one shark in particular - the Big Eye Ragged-Tooth Shark, one of the rarest sharks on the planet. This is, apparently, the "holy grail" for shark biologists. Unfortunately, this illusive specimen didn't turn up, but in the meantime, what did we find?? LOTS-O-SHARKS:
Gulper Shark - Named for their mouths, lined with rows and rows of very sharp teeth, these sharks have the lowest reproduction rate of any shark on planet. Their reflective eyes have been evolving since Jurassic period! | Giant Pacific Sleeper Shark - One of largest sharks in the deep (can grow up to 20 ft long) with eyes that roll back into their heads for protection while they flush out prey along ocean floor. These sharks (and the Gulper) have adaptive, reflective eyes. | Barreleye Fish - Hides its large eyes IN its TRANSPARENT head to avoid becoming prey. Its nostrils, on the outside of its head, look like eyes. Its actual eyes can rotate upward or forward, which helps it to hunt and avoid getting stung by deep sea jelly fish. |
Fetal Dusky Shark - Easily the creepiest fish seen on the program. It was only discovered in 2011 AND it's a CYCLOPS shark!!! | Kitefin Shark - Has huge reflective eyes and sphericals on its head that let it breathe even when it lies completely still (not all sharks can do that). | Wobbegong Shark - This is an ambush hunter, a camouflaged shark that uses "tassels" on the front of its face to draw prey close to jaws. |
NEW shark discovered - a NEW species of Chimera / Ghost Shark - It has big eyes with large, drifting pectoral fins which it uses to propel itself through the water. It has grinding plates in its mouth used to eat shell fish and a razor sharp spine that is loaded with poisons (a haunting relic from 400 million years ago when fish with jaws FIRST appeared in the ocean). I've said it before and I'll say it again. REAL. LIFE. DINOSAURS. Just call him Littlefoot and call it a day. | Frill Shark - Named for its bright red gills. Thought we've known about this shark for over 100 years, it has rarely been seen in its natural habitat. It looks like an alien, with 300 teeth shaped like tiny pitchforks, and it can actually distend its mouth and eat things half its length! It is entirely possible that myths and legends of sea serpents are based on sightings of the Frill Shark. | Lantern Shark - Bioluminescence highlights its spine, which lights up to ward off predators. This is one of only three types of shark that can produce its own light, the result of a chemical reaction within its skin cells (can generate a blue green belly light that allows it to vanish from site if swimming over a predator). |
Goblin Shark - Has ability to distend its jaw in front of its body and then snap it back into place to catch its food - clearly one of the freakiest deep sea sharks there is. It has a "ghoulish" nose called a rostrum peppered with sensors to allow it to scan the sea floor for prey. In fact, it can use those sensors to detect the faintest electrical impulses given off by living creatures. | Saw Shark - Has up to 21 razor sharp spikes on each side of snout, making it quite deadly. Only one other animal on the planet has a snout like this - the much larger Saw Fish. These guys evolved independently and yet developed this same rostrum - WTF! The Saw Fish is actually a giant ray and is, sadly, one of the most endangered fish in the world. | The Crepidater (aka, Longnose Velvet Dogfish) - This guy lives as deep as 7000 feet below the surface (where there is absolutely no light). This shark is the undisputed "king of the deep" and gets its name from its bite - once it finds its prey, it latches on, shaking its head back and forth to tear it, like a dog. |
This island was once a whaling center, and some believe that the whale blood in the water created the perfect feeding ground for some of the biggest (and most aggressive) Great Whites in the world. In fact, the indigenous tribes tell tales of a shark known as the Mango Taniwha - a supernatural, shark-like being said to be as big as a whale. Jeff and Andy aim to get to the bottom of this "shark tale." Yep, I went there. FUN FACT: Andy is one of the only photographers willing to get in the water with these extra-aggressive New Zealand White Sharks...so you know it's going to be good viewing.
Andy immediately starts the expedition off by jumping in with a pack of Great Whites SANS-cage, quickly realizes that was a bad move, and then gets into a cage no bigger than he is...and which looks just as flimsy. While in there, he is surrounded by a gang of circling sharks, just looking for the right moment to snag him. He survives (phew!), but the crew hears about an old, nearby shipwreck thought to be the stomping ground for many Great Whites. Is anyone else picturing the shark gang from Finding Nemo? Because I'm having trouble picturing anything else.
At this point, they drop a shark spy camera down into the water and see a massive shark approach. They miss the opportunity to track that guy, but they hatch a plan to MANUALLY place a fin cam on the dorsal of another Great White so they can track him to the shark hideout. To place the camera on the shark, Jeff and Andy get into a dinghy - a boat smaller than most of the sharks they are luring in - and Andy manages to finagle the camera onto one of the sharks.
They then track the big boy to an area with some underwater caverns, so Andy and "Kina" (a local shark expert and enthusiast) dive INTO the caves. It's a nail-biter, but they escape unscathed, only to then drop a cage into the middle of a feeding frenzy where they are continually pummeled by a pack of Great Whites! The pack suddenly disperses to make way for the Alpha - he's HUGE. He bombards the cage until Andy and Kina yell "uncle" and get the team to pull them up. The sheer size of the shark encountered proves that the legend of Mango Taniwha isn't that far-fetched, and that an even BIGGER shark may be out there.
Dun Dun DUUUUUUUUN.
That's it for day 3 - great programs tonight, DC. I'm impressed.
