Blackgill catshark
The blackgill catshark is a deepwater catshark known from very few specimens, found on or near the bottom on the continental slope, at off the coasts of China and Japan. Specimens can attain a total length of at least, but nothing else is known of its biology. This shark is a potential bycatch of deepwater bottom-trawl fisheries operating within its range, but no specific information is available.
