Roughtail Skate (Bathyraja trachura)
Bathyraja trachura, also known as the Roughtail Skate, is a species of skate found all across the North Pacific Ocean. The Roughtail Skate is a higher-order predator, eating mainly crustaceans and bony fish, although specimens have been found to eat a number of worms and other, smaller animals.
The Roughtail Skate is a bottom-dweller, and can be found all over Axial Seamount and occasionally at Hydrate Ridge. This skate is typically 70 to 80 cm in length, although specimens can be found that are only 90 cm long. Juveniles are born at around 9 to 16 cm long, in distinctively oblong, horned eggs.
