A specimen of angular roughshark (Oxynotus centrina) has been kept successfully in captivity for the first time. Over a period of 24 months, the specimen preyed exclusively on the contents of elasmobranch egg cases, suggesting a specialized trophic niche.
Angular roughshark is a deep-water shark occurring in theeastern Atlantic Ocean and Mediterranean Sea. Biological knowledge of this rarely caught species is limited and it is listed as vulnerable (globally) and critically endangered (Mediterranean Sea) by the IUCN.
