Its range is very wide, taking in coasts of the Andaman and Nicobar Islands, Bangladesh, India (from Gujarat through Kerala and Tamil Nadu to West Bengal), Sri Lanka, South-east Asia, southern China, Japan and Papua New Guinea (Wikipedia, general species account).

It has also been reported from Australia and several Pacific island groups. The account used here is mostly a range list and gives no information on appearance, diet or breeding.
