Also known as the giant butterfly ray, the spiny butterfly ray is a species of butterfly ray native to shallow waters in the Atlantic. Like other rays the spiny butterfly ray feeds mostly on fishes, crustaceans, squid, and other molluscs. The spiny butterfly ray will rapidly strike its prey with the edges of its pectoral fins to stun the prey before it captures it. To withstand this the spiny butterfly ray has a high mass of muscle in the edges of its fins to deliver a harder blow. Currently the spiny butterfly ray is listed as vulnerable as fishing and trawling have caused their populations to decline.
