Description

The Izu stingray is a stingray (Dasyatidae) from shallow sandy and coastal water of the northwest Pacific around Japan. The species reaches about 50 cm across the disc and has a diamond-shaped, flat, brown disc and a long, whip-like tail. Half-buried in sand it searches for molluscs, crustaceans and bottom fish. In its tail it carries a venomous, serrated spine that gives a very painful wound; it stings only in defence when stepped on.
