They are distributed from off northern Baja California around Coronado Island and Cortes Bank, north to the Bering Sea, and west to Japan.

This was the first record of the Deepsea Skate being found in the tropical eastern Pacific Ocean.

The tail is moderately long, narrow, and tapering, terminating in a small, low-set caudal fin.

The egg cases are oblong capsules with stiff, pointed horns at the corners, deposited on sandy or muddy flats.

Deepwater skates feed on benthic organisms, including annelid worms, cephalopods, tanner crabs, shrimps, and bony fishes.
