Snappers are a highly aquatic species. They can be found in almost any types of habitat where there is a permanent water sources, such as ponds, lakes, and slow moving rivers or streams. They are omnivores eating a variety of plants as well as fish, amphibians, invertebrates, aquatic insects and carrion. They are ambush hunters who sit motionless in the water waiting for unsuspecting prey to swim by. They eat while they are submerged under water this allows the water pressure to aid them in swallowing.
Snappers are crepuscular, which means that they are most active at dusk and down. In the water they are usually shy and will retreat from any danger, although they have very few predators in the wild. Approximately each June female snappers leave the water in search of a place to lay her eggs. This is one of the few times that you can find snappers on land. When they are out of the water snappers are very foul tempered and can be quite dangerous. Since they can not retreat back into their shell, the way that many other turtles do, they defend themselves by lunging forward and biting with their very powerful jaws. Although they are slow while on land they can still strike very quickly their neck stretching out around half of the distance of their shell.
