Abstract

In March 2018, an immature female sharpnose sevengill shark Heptranchias perlo was caught by a commercial bottom trawler in the Ibiza Channel. This represents the first substantiated record of the species around the Balearic Islands (GSA05) and the second record from off the Spanish Levantine coasts. This paper includes a review of the records of H. perlo in the Mediterranean as an aid to future conservation assessments.

Keywords: Chondrichthyes; Heptranchias perlo; bycatch; deep-sea shark; shark morphometry; symphyseal tooth.
