Environment: milieu / climate zone / depth range / distribution range
Ecology
Reef-associated; depth range 0 - 95 m (Ref. 96667). Tropical
Indo-Pacific: South Africa to Hawaii.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 8.0 cm CW male/unsexed; (Ref. 343)
Carapace distinctly broader than long, surfaces very smooth; anterolateral margin with 5 lobiform teeth (first 2 teeth never spine-tipped). Chelae very long in adults, reaching or almost reaching maximum width of carapace. Color: quite variable, from dark grey to reddish brown, often with a patchwork of grey and dark brown. One of the most distinctive memebers of the genus because of its very broad and smooth carapace with lobiform anterolateral margins, and the elongate chelipeds.
Occurs from the intertidal zone to a depth of about 20 m (Ref. 343). Subtidal on rocky areas (Ref. 801). Inhabits reefs especially on disturbed reef flats (Ref. 343) or in areas exposed to currents (Ref. 801). Found between crevices or under rock fragments (Ref. 132434).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
