The article identifies the moray eel as the only known vertebrate to use a second set of jaws to both restrain and transport prey.

Not only do moray eels have the razor sharp teeth which you can see, they have double jaws and double sets of teeth! When feeding they use their outer jaws to firmly gip their prey and then the pharyngeal jaw shoots forward and bites the victim and pulls it into the throat.

The Fangtooth Moray Eel is named for its mouthful of fang-like teeth which happen to be semi-transparent. This creature is sometimes known as the Tiger Moray Eel because of its yellow and black coloration.

Most mammals have either diphyodont dentition (two sets of teeth) or monophyodont dentition (only one set of teeth), but there are a few exceptions. Elephants, kangaroos, and manatees have multiple sets of teeth that grow in the back of their mouth and migrate forward as their front teeth fall out.

You won’t have to search hard to find stomach-churning pictures of snakes swallowing large animals and family pets. In his classic book, “The Little Prince”, Antoine de Saint-Exupéry depicts a boa constrictor eating an elephant, not to be mistaken for a hat. So no, an anaconda cannot kill an elephant.

But sometimes your temporomandibular joints can get a little wonky, leading to a popping or clicking noise and sensation when you open your mouth wide. Luckily, this isn’t always a problem. Being able to pop or click your jaw is really only an issue if it causes you pain or uncomfortable symptoms like jaw stiffness.

Small, young pythons may be attacked and eaten by a variety of birds, wild dogs and hyenas, large frogs, large insects and spiders, and even other snakes. But adult pythons are also at risk from birds of prey and even lions and leopards.
