Shortnose demon catshark

The shortnose demon catshark (Apristurus internatus) is a catshark of the family Scyliorhinidae found only in deep water in the East China Sea. Its length is up to 40 cm.[2] A. internatus is known only from the holotype (a 49.1-cm-total length female) and a paratype (a 40.3-cm male), both caught in the East China Sea, probably taken as bycatch in deepwater trawl fisheries. Insufficient information is available to assess this species' conservation status. The reproduction of this catshark is oviparous.[2]
