These crocodilians are restricted to rivers, lakes and swamps in low lying areas, especially the peat swamp forests of Borneo, Sumatra and Malaysia.
Juvenile animals will feed on invertebrates, including shrimp, and aquatic insects. Adult animals have a varied diet that can include fish, monitor lizards, monkeys, waterbirds, and turtles. There are now several records of Tomistoma killing cattle, so these crocodilians are large and powerful animals.
Tomistoma are found in low numbers throughout their range. We have very little information on historic populations, so it is difficult to assess how the population has varied over the years. Threats to the species include drastic loss of peat swamp forest habitat to logging, fires, and conversion of these areas to palm oil plantations, as well as entanglement in fishing nets, and opportunistic removal of young animals and eggs by residents and crocodile farmers.
