Overview

The Bombay sea snake is a marine elapid associated with the coastal waters of western India, including the seas near Mumbai (formerly Bombay). It is one of several regionally described Hydrophis species from the Indian coastline.

Like other members of its genus, it is a fully aquatic snake adapted to life at sea, and its biology and distribution remain less thoroughly studied than more widely distributed sea snake species.
