Rocky fish look like eels or snakes, up to 35cm long. They have no jaws but have a round mouth like a disc, full of sharp teeth, according to Mother Nature Network. This species usually lives on the Atlantic coast of Europe and North America, in the Western Mediterranean and the Great Lakes.

Rocky grouper is also known as vampire due to parasitic life, sucking blood and body fluids of other fish species. Adult fish bite into the body of the prey, sticking with their teeth and tongue, sucking the animal's blood until it is full. Many fish die after being sucked by bloodfish, but most cases continue to live.

In fact, very few people see this fish with their eyes. They are born in fresh water, then swim into the ocean as adults. By the breeding season, they swim back to their birthplace.

Leather turtle

Leather turtles are the largest sea turtles in the world. The largest known individual has a length of 3 meters, weighs 916kg. On average, a turtle consumes about 73% of its body weight per day.

The sharp spines in the turtle's mouth have an inverted, sharp and sharp cone. They act like teeth, helping leather turtles to keep food in their mouths. The main food of turtles is slow moving jellyfish.

Leather turtles have a specially designed digestive system that helps them consume a lot of food, but they cannot distinguish jellyfish and other floating plastic trash in the water. This restriction causes the garbage to become stuck in the throat and endanger the turtle.

Pacu fish

Fish Pacu is a freshwater fish that lives in South America, which is related to carnivorous piranhas. They live by eating nuts and fruits falling into the water. The straight, cubic teeth of pacu fish make many people confused with human teeth.

Pacu fish can grow to four times the size of adult feet and weigh up to 25kg.

The hippopotamus is a herbivorous mammal, half-watered half-terrestrial in African rivers, lakes and swamps. They possess large, sharp, and sharp teeth that can open wide. The hippopotamus jaw can crush one or two crocodiles about 3 meters long.

The hippopotamus is plump, almost hairless. Although the average weight is up to 1.5 tons, but hippos are capable of running at a speed of nearly 50 km / h. They become especially aggressive when the territory is violated.

Goblin sharks

Leprechaun sharks are deep-sea creatures about 1,200 meters deep and have a rather bizarre body, including a flattened muzzle containing long, sharp teeth. Their jaws can openly reach the nose like the sword above.

Adult males are about 2.4 to 3.1 meters long, females are 3.1 to 3.5 meters long. The largest individual was found to be 3.9 meters long, weighing 210kg. Interestingly, 25% of this fish's body weight is liver.

In the deep sea, the red rose of goblin sharks becomes black, so they can easily catch prey and avoid enemies without being detected.

Hagfish fish

Hagfish is one of the most exotic jaws, living in the deep and cold waters of the world. They possess double teeth with sharp, sharp teeth like combs, perfecting the function of tearing meat.

The hagfish have a slippery layer of black skin, a body diameter of about 4cm, and a length of 30 - 40cm. They usually eat prey by biting a hole to reach the internal organs, then consume prey from the inside out.

Vampire fish

Vampire fish is a freshwater predatory fish. They own two fangs up to 15cm long protruding from the lower jaw, used to pierce the prey. The special structure of the skull with two upper jaws allows the vampire fish to hide their fangs in the mouth and prevent them from stabbing themselves.
