Description

The blackmouth catshark is a slender deep-sea catshark of the family Scyliorhinidae reaching about 75 cm. The brownish body bears a row of dark saddle blotches and spots on the back, and the inside of the mouth is strikingly black, giving the species its name. It lives along continental slopes of the eastern Atlantic and the Mediterranean, usually between about 200 and nearly 2000 metres. On and above the bottom it hunts crustaceans, squid and small fish. The species is egg-laying and deposits eggs in horny capsules throughout the year. It is harmless to people and is landed mainly as bycatch of deep-sea fisheries.
