Snapping turtles are the oldest reptiles in existence, and one of the largest freshwater turtles in the world. They are known as the king of freshwater animals. They are divided into two categories, commonly known as predators and crocodiles. The predator is also known as the true snapping turtle (produced in the southeastern part of the United States in North America), and the small alligator is also known as the pseudo snapping turtle. There are four subspecies, namely North America, Florida, South America, and Central America. Common ones are North America and Florida, of which Florida is more expensive due to some man-made reasons. Due to its large size and aggressiveness, it has fewer natural enemies except for alligators. Once lost its habitat due to human hunting, it was listed as a vulnerable species by the World Conservation Union.
The tongue of a true snapping turtle has a bright red and bifurcated worm-like fleshy process, which is connected to the tongue by a circular muscle in the middle. Both ends can freely stretch and move, and the tongue is shaped like a worm, used to lure fish.
