Abstract

A spent Gonatus antarcticus female (mantle length 340 mm) was caught in Falkland Islands waters by a fishing vessel in November 2010. Squid genus Gonatus spawn at depths of >2000 m and findings of such females are rare all over the world. It is the third capture of a mature female of this species, and the shallowest capture for adult squids of the genus. Another G. antarcticus, an immature female, of the record size of 470 mm (mantle length) was caught in June 2011 in Falkland Islands waters, also by a pelagic fishing vessel.
