who is the guy that got killed by a stingray

Manta ray Mantas evolved from bottom-dwelling stingrays, eventually developing more wing-like pectoral fins.[8] M. birostris still has a vestigial remnant of a sting barb in the form of a caudal spine.[9] The mouths of most rays lie on the underside of the head, while in mantas they are right at the front.[10] Manta rays and devil rays are the only ray species that have evolved into filter feeders.[3]
