 The typical hunting strategy of the diamond stingray is to cruise just above the sea floor , landing atop any prey encountered . It then quickly <unk> its body up @-@ and @-@ down with its disc , producing negative pressure to extract the prey from its burrow . This ray has also been known to excavate large pits by undulating its disc and spitting jets of water , so as to uncover buried prey . Diamond stingrays are frequently trailed by smaller fishes , including Mexican <unk> ( <unk> <unk> ) , <unk> <unk> ( <unk> <unk> ) , <unk> <unk> ( <unk> <unk> ) , spinster <unk> ( <unk> <unk> ) , and long @-@ spine <unk> ( <unk> <unk> ) , which take advantage of the invertebrates stirred up by the ray 's activities . Known parasites of this species include the <unk> <unk> <unk> , A. <unk> , A. <unk> , and A. <unk> , <unk> <unk> , <unk> <unk> , and <unk> <unk> , the <unk> <unk> <unk> and <unk> <unk> , and the <unk> <unk> <unk> .
