The mata mata inhabits slow moving, blackwater streams, stagnant pools, marshes, and swamps ranging into northern Bolivia, eastern Peru, Ecuador, eastern Colombia, Venezuela, the Guianas, and northern and central Brazil. The mata mata is strictly an aquatic species but it prefers standing in shallow water where its snout can reach the surface to breathe.
Behavior
The appearance of the mata mata's shell resembles a piece of bark, and its head resembles fallen leaves. As it remains motionless in the water, its skin flaps enable it to blend into the surrounding vegetation until a fish comes close. The mata mata thrusts out its head and opens its large mouth as wide as possible, creating a low-pressure vacuum that sucks the prey into its mouth, known as suction feeding. The mata mata snaps its mouth shut, the water is slowly expelled, and the fish is swallowed whole; the mata mata cannot chew due to the way its mouth is constructed.
Mata mata turtles are readily available in the exotic pet trade and are quite expensive to obtain. Due to their unique appearance, they make interesting display animals. They also grow quite large. However, mata matas are not active hunters, so, like the alligator snapping turtle, they need less space than a large, active species.
As with all aquatic turtles, water quality is one of the keys to keeping this species successfully in captivity. Warm, acidic water is the best type used with a high tannin content that should be maintained all year round. Moderate to heavy filtration is recommended.
