[00:00:00]The great white shark. The great white shark is probably the last animal you'd want to bump into in the ocean. They are huge, fast, and have super sharp senses that make them the top hunters of the sea. Don't let their giant size fool you. They are sneaky, too. With a mouthful of 300 3-in teeth that always grow back if they break, they will eat almost anything they can catch. Movies make us think they are mindless human eaters, but that's just not true. You only have a one in 4.3 million chance of getting hurt by one. They actually prefer seals, sea lions, fish, and other sharks. They can smell their next meal from miles away. So, as long as there are other fish in the sea, we aren't on the menu. The killer whale, orca. Next up, the killer whale or orca. They might look like big fish, but they are actually mammals, closer to dolphins than actual whales. At about 30 ft long, they are the biggest hunters on Earth, making them the true kings of the ocean.

[00:01:04]Because nothing hunts them, orcas eat a mix of fish, seals, sea lions, and even other whales. They are incredibly smart and hunt together in packs, showing off amazing teamwork. These guys are so big and scary to other sea life that even great white sharks run away when an orca shows up. But, don't worry, there are no records of a killer whale attacking a human in the wild. In some places like Norway, people even swim right next to them. The tiger shark. Imagine stacking two Shaquille O'Neals on top of each other. That's how long a tiger shark can be, reaching around 14 ft. But, their size isn't just for show. These hunters are not picky eaters. They are the second most aggressive shark after the great white, making them fierce and always hungry. They are sometimes called the oceans garbage can because they will eat almost anything. Turtles, fish, seals, and even actual trash. Their teeth might only be an inch long, but they have jagged edges like a steak knife and can saw through bone. They usually hunt alone, but the good news is they rarely look at humans as food. The sperm whale, meet the heavyweight champions of the ocean, sperm whales.

[00:02:23]They are the biggest toothed hunters on Earth measuring 50 to 60 ft long and weighing up to 60 tons. But they aren't just big and clumsy. They are highly smart and live in groups working together like a team of Navy commandos.

[00:02:38]They use natural sonar sending out sound waves to find their food and can hunt in the pitch black water 4,000 ft deep.

[00:02:47]They are the only animals big enough to eat giant squids. The oldest females usually lead the group and make the decisions. While they are huge, smaller killer whales sometimes attack them. And be careful, they aren't totally harmless. They have been known to crash into ships and even sink them. The bull shark. The bull shark is one of the meanest hunters in the sea right up there with the great white and the tiger shark. You can tell it apart by its chunky body. What makes it really special is where it can live. It can swim in both salty ocean water and fresh water. So, if you see a big shark in a river or a lake, it's probably a bull shark. They can grow up to 11 ft long and have the strongest bite in the shark family. Pound for pound, they can bite through flesh and bone faster than even a great white. While rare, bull sharks are responsible for a lot of shark bites on humans. So, it's best to stay far away from these meat crunching machines.

[00:03:50]The hammerhead shark. With its famous T-shaped head, the hammerhead shark looks a bit weird, but there's a great reason for it. Scientists think their wide-set eyes give them a super wide view of everything around them. Plus, their huge nostrils let them smell food from miles away. It's like having a built-in radar system. They live in warm waters all over the world and come in different sizes. The great hammerhead can grow up to 20 ft long, but most are about the size of a small car. Even though they are big, they are pretty safe to be around. Since the year 1900, there have only been 16 recorded hammerhead bites on humans, and none were deadly. The goblin shark, think of the goblin shark as the creepy cousin of the shark family. It has a face only a mother could love. Luckily, you probably won't ever see one because they live deep in the dark parts of the ocean, over 4,000 ft down, where only submarines can go. They probably evolved to look so strange because of the crazy water pressure down there. They can grow up to 13 ft long and eat deep-sea fish, squids, and crabs. If their face wasn't scary enough, their jaws can actually shoot forward to grab their food like an extending claw. The saltwater crocodile, at an average of 17 ft long, saltwater crocodiles are the closest thing we have to real-life dinosaurs. Found in Australia and Southeast Asia, they are the biggest hunting reptiles in the world. They mostly hang out in rivers and swampy waters, waiting completely hidden until an animal gets too close.

[00:05:36]Then, bam, they strike super fast and crush their meal. They have the strongest bite force in the world, 3,700 lb of pressure.

[00:05:47]For comparison, you only need 200 pounds of pressure to bite through a tough steak. They are also surprisingly fast, able to swim and run up to 18 miles per hour. Definitely keep your distance.

[00:06:01]There have been around 100 attacks on humans since the 1970s. The giant squid.

[00:06:07]Old sailor stories talk about giant sea monsters and the giant squid is like a sci-fi creature come to life. It has a 40-foot body the size of a school bus and tentacles that look like giant noodles. We rarely see them because they live way down deep, at least 3,200 feet underwater. They have the biggest eyes in the whole world, which helps them see in the dark, and a sharp beak that can slice through almost anything.

[00:06:38]They eat any deep-sea fish smaller than them. The only thing they have to fear is the bigger, stronger sperm whale.

[00:06:46]Because they live so deep, scientists still don't know a whole lot about them.

[00:06:51]The leopard seal. When the leopard seal isn't hunting baby penguins, it's going after fish. They sit right at the top of the food chain in the icy waters of the Antarctic. They are way bigger than normal sea lions, measuring up to 11 feet long and weighing around 1,000 pounds. With their rows of sharp teeth, their faces look almost like reptiles.

[00:07:16]The only animal brave enough to hunt a leopard seal is the killer whale. On land, the leopard seal is king, eating penguins, birds, and even smaller seals.

[00:07:27]They like to be alone and will fiercely protect their space. Attacks on humans are rare, but sometimes they like to play with divers or even play with their food before eating it. The mako shark.

[00:07:40]The mako shark is the sports car of the ocean. It's the fastest swimming shark in the world. If the great white is Superman, the mako is the flash. Long, pointy, and smooth, it can swim up to 45 mph thanks to its powerful tail. They aren't small, either, growing up to 15 ft long. With that speed, they can chase down squids, tuna, and other sharks.

[00:08:07]Unlike the great white, their teeth aren't jagged because they mainly eat slippery fish instead of big chunks of meat. They rarely attack humans, but because they are so fast and aggressive, it's considered too dangerous to swim near them. The blue marlin. Last but not least is the blue marlin. At 14 ft long and over 2,000 lb, it's a massive, beautiful, and lightning-fast fish. They can swim up to 80 mph, making them one of the fastest animals in the sea. They use this speed to hunt down huge groups of fish. Blue marlins are like the sword fighters of the ocean. They use their long, pointy snouts to slash right through groups of tuna and squid before eating them. Nature gave them a sword, and they definitely know how to use it.
