We dive back in time and into the oceans over a half a billion years ago. Just, you know, because we can. Whoa, watch out! It's not Megalodon or giant sea reptiles you need to look out for a year. It's a bizarre, unearthly-looking creature called Enamelokaris.

1:00The name means unlike any other shrimp. And I think you'll agree. It looks like a nightmarish cross between a shrimp and a modern-day centipede. Two tentacles protruding from its face, each lined with razor-sharp teeth. Oh yeah! And this thing was about the size of your leg. With a wave-like movement of the flaps on each side of its body, it was graceful for a terrifying creature. It was also more advanced than any other life on this planet at the time. Especially those huge eyes. You have only one lens in each of yours. This giant shrimp had 16,000. That's four times more than a common house fly. And you know how good their vision is. Good enough to dodge that swatter every time. All this allowed Annie to become one of the first animals on this planet to feed on others. Yep, here it is. Earth's first hunter. Its favorite meal? Trial ofites. Hey, try a bite. Those are the ancient ancestors of crabs.

2:01Some of their fossils have marks on them in the same shape as the monster shrimp's mouth parts. Terrorism of the past like this got to be so giant thanks to more oxygen in the atmosphere. A perfect example of this, Megan Naropsis. Imagine a dragonfly. Now make it as big as a cat. And with a wingspan longer than your arm. Megan, the monster sized dragonfly, could easily grab other insects or even small animals. And she ruled the air with quick movements. Back then there were still no large birds or other airborne enemies for this behemoth bug. So it was safe and free to grow as large as this planet would allow. Piranhas of the past were also jumbo sized. Mega piranha was about three times the size of the river terrors we have today. Protein is now at Starbucks and it's never tasted so good.

Its bite force was about the same as a tiger's. And those striped kitties bite down two times harder than lions. That means it probably not only dined another fish and any land creatures that, you know, got too close to the water. But it could also easily crunch down on large turtles and other unlucky shell creatures. And fun fact. Modern day piranhas bark like dogs when they're about to enter a confrontation.

4:06It actually says more like a frog's ribbit. But make you wonder, what did this mega sized ancient cousin sound like? A bear roaring? How about giant sea scorpions the size of your bed? Go back about 460 million years and you'd see them swimming under you and watch out for that tail. Scientists still don't know if these creatures could use it to inject venom like your standard land scorpion. But something tells me I wouldn't want that thing anywhere near me. Then there's this guy, Therazino Sores. Terry looks sort of like a goose with long arms. Oh, and did I mention this goose dino is about two stories tall and longer than a bus? Yeah. Its arms make the T-Rexes look even more bite-sized. Each 8 feet long almost triple the length of T-Rexes. And on the end razor sharp claws the size of your whole arm.

5:06Now don't worry about those lengthy claws too much though. Terry probably used them to cut through giant termite nests. So this huge reptilian goose was more interested in eating bugs and plants. Another mega monster for you? Megatherium. The giant ground sloth could look a giraffe straight in the eye and weighed as much as a hippo. It moved mainly on its hind legs and used its massive tail as support. It had huge paws with colossal knife-sized claws. The sloth could use them to defend itself from enemies and to bend tree branches in search of food. But the biggest danger to the giant ground sloth wasn't dinosaurs or saber-tooth tigers. It was our own species. Yup, human showed up just in time to meet this fellow. And to eat them up. Titaniboa was a terrifying 50 foot snake. As long as the great megalodon itself. It was also more than two times heavier than the heavyweight champion among snakes today.

6:10The green and the condom. Crocodiles were irregular on this serpent's menu. Titaniboa could swim three times faster than the fastest Olympic swimmer our species has ever seen. It was quicker and more dangerous than the water than outside it. And don't forget the boa part of the snake. This massive snake wasn't venomous. Instead, it liked to squeeze. Remember that giant shrimp from earlier? Well, opabinia looks like its teeny tiny finger-sized cousin. And instead of two toothy tentacles, this thing had a vacuum hose coming out of its face. On the end of that trunk, it looks like a single crab claw. Add five eyes and a mouth under its head. And you've got a recipe for something not of this planet. Only it is. This creature uses trunk like an elephant does. Its claw grabbed food from the bottom of the ocean and brought it up to its mouth. This thing is so weird looking that, apparently, when the scientists who discovered it-

7:14is unpredictable. But you can flare less with epglysss. A once-monthly treatment for moderate to superior eczema. After an initial four-month or longer dosing phase, about four and ten people taking epglysss, achieved itch relief and glare are almost glare skin at 16 weeks. And most of those people maintain skin that's still more glare at one year with monthly dosing. Epglysss, LibriKizumap, LBKZ. A 250-milligram-per-two-milliliter injection is a prescription medicine used to treat adults and children 12 years of age and older, in a way at least 88 pounds or 40 kilograms with moderate to severe eczema. Also called atopic dermatitis that is not well controlled with prescription therapies used on the skin, or topicals, or who cannot use topical therapies. Epglysss can be used with or without topical corticosteroids. Don't use if you're allergic to epglysss. Allergic reactions can occur that can be severe. Eye problems can occur. Tell your doctor if you have new or worsening eye problems. You should not receive a live vaccine when treated with epglysss. Before starting epglysss, tell your doctor if you have a parasitic infection. Ask your doctor about epglysss and visit epglyss.lily.com or call 1-800-LilyRX or 1-800-545-5979. Presented his findings to an audience, they all laughed as if he were joking.

8:18Now, a real-life monster, the Tully Monster. From a distance, it looks a bit like messy. At long neck and teeth line jaws, but get closer and you'll see it's more like a long nose with a mouth attached at the end, like a mosquito. Its eyes are further back, sticking out of tubes all snail-like. Tully was an ancient mollusk about the size of your forearm. It probably dined on jellyfish and shrimp 300 million years ago. Thylacus smileus will put a smile on your face, as long as you don't get too close. No, it's not a relative of the saber-toothed tiger. It was a marsupial, making it more related to a kangaroo than anything. And if you compare them to body size, its fangs were actually longer than the saber-toothed tigers. And they grew continuously. As for that beard on its chin, that's actually all chin. The lower jawbone grew down to a point under the mouth.

9:19Those fangs were rooted to the skull, going way back to its eyes. When the mouth was closed, that bony beard protected the long sharp teeth from breakage. Stag andapolis, not to be confused with Minneapolis, might look like a big crocodile with a squished-in snout, but it was mostly harmless. Its small head and very few teeth meant the reptile didn't have much to work with when protecting itself. That's what all those armored scales were for. And no need for huge fangs or long rows of razor-sharp teeth when you're a plant eater. That beak-like tip on its nose allowed the stag to dig up plants. So, really, this reptile was more like a 10-foot-scaly pig than a crock. Basilosaurus was a type of ancient whale that lived on our planet about 45 million years ago. Not quite as long as a blue whale, but this guy was still big enough to munch down on other whales and even sharks. Some people believe these monsters could still exist today.

10:21Eyed witnesses claim to have seen a giant sea dragon and Basilosaurus fits the description. Plus, 90% of our oceans are unexplored. There's plenty of space to hide a sea monster. But scientists haven't found any fossils of this ancient whale younger than 3.7 million years. So, this myth is busted. Stegosaurus is one of the most recognizable dinosaurs that ever lived. It can easily be distinguished by those huge spikes on its tail and the bony plates on its back. It was twice as long as a giraffe and nearly five times heavier. But, compared to its body size, it had the world's smallest brain. It was no larger than a dog's. Pelagornus had the largest wingspan of any bird ever discovered. It was twice the size of the largest bird today, the wandering albatross. Such huge wings made it hard for the bird to take off. It could only do so by jumping off cliffs.

11:23And when it finally spread its wings, this giant could only go about 40 miles per hour. The fastest bird today can reach speeds five times that. New Year, new me? Cute!
