Mata Mata

Chelus fimbriata

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The mata mata is one of the strangest turtles in the world: a rough shell bristling with ridges, a triangular, flattened head covered in flaps of skin, and a broad, flexible neck that makes it look like submerged leaf litter. It does not chase its prey: it stays motionless on the bottom and swallows them by suction, opening its mouth all at once and creating a vacuum that drags the fish in.

Fun facts

  • It neither chews nor bites: it opens its mouth all at once, expanding its throat, and generates a suction so abrupt that the fish is dragged in with the water in a fraction of a second; it then pushes the water out through the sides.
  • Its camouflage is total: the flaps of skin on its head and neck mimic rotting leaves, and the algae growing on its shell make it indistinguishable from the bottom.
  • Its snout ends in a narrow tube that it uses as a snorkel: it can breathe without moving the rest of its body, staying submerged and motionless for hours.
