It is found from the Eastern Bering Sea and Alaska to Baja California and the Gulf of California. The longnose skate is found at depths of 9–1,069 m (30–3,507 ft) and often deeper than the big skate.[2][3] The longnose skate has only recently been associated with the genus Beringraja, having been previously included in Raja until genetic evidence supported reclassification.[4][5] This issue has not be completely resolved and the scientific name "Raja rhina" is still in widespread use.[2][1]
