Risk level of the species

Risk level of the species critically endangered


They live in lowland tropical regions in southeast Asia. Their aquatic lifestyle has led to them having eyes and nostrils that jut out from the top of the head. The body is covered with brownish scales with a large snout, indicative of a generalist feeding strategy. They prefer fish, although they can also capture reptiles, amphibians and small mammals. The young feed on arthropods, insects, crabs and amphibians. Like other crocodiles, they cannot chew, so that they have to shake the prey in order to break it up into pieces with their teeth.
Of medium size, although males can reach lengths of almost 4 metres, they are generally not considered dangerous to humans.
The reproductive period takes place during the wet season. Females build a type of nest some metres away from the water, where they lay 20 to 50 eggs. The nest is shaped like a monticle, forming a barrier of earth, leaves and other plant material, ending up with diameters of some 150 cm and heights of 30 cm. The female regularly visits the nest until the eggs hatch and then transports the babies in her mouth to the water.
It is one of the most endangered crocodiles in the wild, although there are many in captivity, as they are bred to obtain their valuable skin. Besides the animals in captivity, there have been some introduced into the wild, where they had been practically exterminated. Their main threats are the transformation of their habitat into farming land and hunting to obtain their skin. In many regions of their distribution area, the local population protects them, considering them sacred animals.
