Black finless porpoise
The Indian finless porpoise (Neophocaena phocaenoides phocaenoides), a finless porpoise, is one of seven porpoise species.  Throughout their range, these porpoises stay in shallow waters, up to 50 m (160 ft) deep. They live close to the shore, in waters with soft or sandy seabeds, or in estuaries and mangrove swamps, such the Indus River delta.
