Matamata

1 Overview

The matamata (Chelus fimbriata) is a bizarre South American side-neck with a flattened, leaf-like head, tubercle-covered shell, and fleshy neck fringes that camouflage it among leaf litter. It is a sit-and-wait ambush predator.

SOURCE NOTE: the source spelled it ‘Chelus fimbriatus’; the correct binomial is Chelus fimbriata.

2 Appearance

The carapace is rough and brown, mimicking bark; the triangular head is flat with a long snout, and the neck bears skin flaps. Adults reach 40-50 cm.

3 Care & Temperament

Needs a large, deep, well-filtered aquarium with a soft substrate and dim light; it is stationary and shy. Shell rot and skin issues follow poor water.

It strikes live fish underwater by creating a vacuum – feed accordingly.

4 Habitat & Environment

Slow blackwater rivers and flooded forest. Keep warm, clean, soft-bottomed water with a basking option.

5 Diet & Feeding

Carnivorous: live fish are the natural staple; some accept thawed prey. Feed in water and avoid handling the delicate neck.
