1Anaconda

The jaws of anacondas are held together with stretchy ligaments so they can open wide enough to swallow prey whole. With their large size, anacondas kill their prey by wrapping their bodies around and suffocating their prey. Their menu consists of birds, fish, pigs, rodents, deer, and other reptiles like turtles; there is no record of them eating humans.

The one main feature that an anglerfish is famous for is its fleshy growth that glows in the dark. They use their luminescent mini lamp to lure the prey before capturing the poor thing with their large mouth. This type of fish is able to distend its jaws and stomach with ease thanks to the flexibility of its bones. In fact, anglerfish are capable of eating things twice their own size. Scary look and all, they make a fascinating actor in the animated movie Finding Nemo. This one is one ugly kind.

3Argentinian Horned Frog

With a rounded body and huge mouth, Argentinian Horned Frog aka Pacman is one interesting species to know. They are also very popular pets as well at some point.

With that large mouth, they are not afraid to swallow meals like mice, small reptiles, or even large spiders. If threatened, these bold animals can deliver a painful bite from their odontoid projections along their bottom and top jaws.

These sharks have remarkable mouth sizes yet with personalities of docile creatures that are super kind to divers.

The fascinating thing about this large shark is that they mainly feed on plankton, yes they are not predators. On top of that, the sharks usually swim with its mouth open and catch whatever it goes through. They normally feed near the ocean surface where and when plankton is abundant, and they don’t use their teeth at all.

6Hippopotamus

The mouth of an adult hippo is roomy enough for 36 teeth including tusks, and they can open that mouth at a 180-degree angle. Guess what, that is a good way to impress females while deterring the competing males. Just so you know, hippopotamuses are very aggressive and they are not afraid to attack humans at all.

Doing so allows them to determine which one is larger, and that establishes dominance.
