The matamata turtle, Chelus fimbriatus, is a species of freshwater turtle with spiky ridged scales. It has very specific physical features compared to other turtles.
Profile
Lifestyle
The matamata turtle does not move around much and is capable of remaining motionless for hours on end. Hidden away on the muddy bottom of swamps, it is invisible with its shell covered in bumps and algae.
To breathe without coming up to the surface, it stretches out its long neck and pokes out a short snorkel-like snout where its nostrils are located. In murky waters, the two sensory barbels around its mouth enable it to detect its prey.
Distinctive features
With its spiny scales and rocky-looking head, this turtle is the queen of camouflage. It may weigh more than 10 kg as an adult, but it has no trouble blending in with the muddy riverbeds of the Amazon basin.
Anecdote
In turbid waters, the two sensory barbels around its mouth enable it to detect its prey more easily. Carnivorous, it feeds mainly on small fish.
