Environment: milieu / climate zone / depth range / distribution range Ecology

Benthic; depth range 130 - 2047 m (Ref. 2704), usually 200 - 2000 m (Ref. 78375). Deep-water; 64°N - 33°S, 81°W - 7°E (Ref. 2747)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions

Southeast Pacific and north Atlantic.

Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 8 - 9.926 cm Max length : 15.5 cm CL male/unsexed; (Ref. 101417); 17.7 cm CL (female); max. published weight: 863.00 g (Ref. 2720)

Maximum length for females from Ref. 2747. This is the largest epibenthic brachyuran crab of the Family Geryonidae (Ref. 2689). Bimodal length frequency for males and unimodal for females. More males and larger individuals in shallower substratum and increasing number of females and smaller individuals in deeper substratum (Ref. 2677, 2747). This is also a target species of gillnet operators in Northeast Atlantic fisheries (Ref. 2740).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Inferred from the gonadosomatic index (GDI), presence of ovigerous females and evolution of the maturity stages, occurs in autumn and winter. This supports an annual reproductive cycle. Sexual maturity with carapace lengths from 7.3 to 9.7 cm (Ref. 2747, 2751).
