 The diamond stingray is found in the eastern Pacific Ocean from southern California to northern Chile , as well as around the Galápagos and Hawaiian Islands ; it is very abundant around Baja California and in the Gulf of California . At the northern and southern extremes of its range , it is generally only present during periods of suitably warm water brought about by El Niño . There is a record of this ray from off British Columbia , which is unconfirmed and would be highly anomalous as it is known to be a tropical and warm @-@ temperate species .
