Description

The bluntnose stingray is a stingray of the family Dasyatidae from the western Atlantic. The species has a rhomboid, brown body (disc) and a long, whip-like tail with a serrated, venomous spine, and can reach about 1 m across. It lives in shallow coastal waters, estuaries and the surf, where it feeds on the bottom on fishes, clams, worms and shrimps. The species is livebearing. Because it often lies buried in the sand, it regularly causes puncture wounds to bathers and waders.
