Biology     Glossary (e.g. epibenthic)

The total body length of largest specimen ever recorded is 37 cm; and the total body length is 14 to 34 cm (male) and 9 to 24 cm (female); and carapace lengths of 6 to 13 cm (male) and 4 to 9 cm (female); with an average size of 21 to 28 cm (male) and 19 to 21 cm (female). The specimens from Amsterdam are slightly smaller than those from St Paul Island (Ref. 4). Occurs at depths of 0 to 60 m on rocky or gravel bottom, being most numerous in the kelp zone between 10 and 35 m (Ref. 4). Confined to oceanic islands and seamounts (Ref. 105202). It is nocturnal and feeds on plants and dead animal matter (Ref. 4). Partially vegetarian (Ref. 105260). Reported to exhibit cannibalism among its deep-water populations (Ref. 105202).
