摘要

Cephalopod molluscs possess a variety of reproductive organs and display diverse sexual behaviours, justifying their nickname as ‘oceanic intellectuals’ (Boyle & Rodhouse, 2005). However, while courtship and mating of shallow-water cuttlefish, octopuses and squid have been filmed and well documented by divers and remotely operated vehicles (Sauer et al., 1997; Hanlon, 1998), what happens during mating of deep-water cephalopods remains largely a mystery (Nesis, 1995), apart from one observation of possible mating behaviour in Brachioteuthis beanii (Roper & Vecchione, 1996).
