Biology and Ecology
Within its range, the blackmouth catshark is one of the most abundant sharks over the upper and middle continental slope. It is nomadic in nature and may be found alone or in groups. Relatively slow, this shark swims with strong eel-like (anguilliform) undulations of its body. It often cruises just above the sea floor, perhaps taking advantage of the ground effect (a reduction in the drag on a wing when close to the ground) to save energy. It has also been seen resting motionless on the bottom. Known predators of the blackmouth catshark include the kitefin shark (Dalatias licha) and the European flying squid (Todarodes sagittatus). Parasites that have been documented from this species include the tapeworm Ditrachybothridium macrocephalum and the protist Eimeria palavensis.
