 At least one fatality off southern California has resulted from the long , venomous tail spine of the diamond stingray . However , it is not aggressive and will usually flee given the opportunity . This ray is not found off the United States in sufficient numbers to be economically important . Elsewhere in its range , it is caught in substantial numbers for human consumption , both intentionally and as <unk> ; the pectoral fins or " wings " are sold fresh or <unk> and salted . The International Union for Conservation of Nature ( IUCN ) notes that the diamond stingray 's low reproductive <unk> renders it susceptible to population depletion , but currently lacks enough biological and fishery data to assess it beyond Data <unk> overall , or in the U.S. , Central , and South American parts of its range .
