This crocodile only reaches 2,2 m in length. It has four well-developed legs, the hands have 5 fingers while the feet only 4, they have a very robust and laterally flattened tail, which they use to propel their swimming.

The eyes and nostrils are above the waterline, which allows them to stalk their prey while remaining hidden in the waters where they live.

Among their adaptations to life in water we find a type of valve in the nostrils and ears, which when closed prevents the entry of water during immersion.

They are the only reptiles with a secondary palate, which allows them to eat their food in water without it drowning them. Their eyes have a transparent third eyelid that protects them.
