Their range is northwest India to southeastern China, Malay peninsula, southern India, Sumatra, Java, and Borneo.
They inhabit rivers, creeks, estuaries and coastal waters.
60 to 64 days
While solitary individuals may be observed, they usually live in loose family groups of about 12 individuals. They have vocabularies of 12 or more calls in addition to basic instinctive cries. These diurnal animals will only occupy areas with a permanent body of water and some tree cover. They live in large, underground burrows with a ventilation shaft leading to the surface and an exit tunnel opening about 3 feet under water.
Using their sensitive fingers to find clams in shallow water, they bring them to shore and pile them up, and after a few hours in the sun the clams open and the otters eat them. They spend much of their time playing in the water, and will fall to water when danger approaches. When they hunt in rice fields they aid farmers by ridding the fields of crayfish that damage crops. Like raccoons, they sometimes "wash" their food before eating it. If captured young, these otters make intelligent and charming pets. Malayan fisherman have even trained them to drive fish into nets for them.
Females have an estrous cycle of 24 to 30 days with an estrus of 3 days. They may produce two litters in a year. The young do not open their eyes until about 40 days, and they first swim at 9 weeks. Solid food is first taken after about 80 days. The male brings food for both the mother and the young, and helps in raising the pups. Males and females appear to mate permanently.
