Ecology
Benthic; depth range 180 - 750 m (Ref. 106911), usually 400 - 500 m (Ref. 106911). Tropical, preferred 26°C (Ref. 107945); 3°S - 33°S, 31°E - 46°E (Ref. 4)
Southwest Atlantic and Indo-West Pacific: from Kenya to Natal.
Length at first maturity / Size / Weight / Age
Maturity: Lm 4.9, range 3 - ? cm Max length : 20.5 cm TL male/unsexed; (Ref. 122061); 20 cm TL (female)
It has a maximum total length of 20.5 cm (male) and 20 cm (female); and carapace lengths of 4.5 to 8.8 cm (male) and 3.7 to 8.3 (female). Minimum depth range from Ref. 122059. Occurs at depths from 200 to 750 m, but most common between 400 and 500 m (Ref. 4). Occurs along the edge of the continental slope on soft muddy substrata (Ref. 106911).
