Portunidae
Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthopelagic; depth range 0 - 100 m (Ref. 132434). Tropical, preferred 24°C (Ref. 107945); 42°N - 38°S, 79°E - 154°E (Ref. 106948)
Indo-West Pacific: from Honshu, Japan, west to eastern India and Sri Lanka, and south to New South Wales, Australia.
Length at first maturity / Size / Weight / Age
Maturity: Lm 13.1 range ? - ? cm Max length : 15.9 cm CW male/unsexed; (Ref. 125642)
Carapace tough to granulose, regions discernible; front with 3 acutely triangular teeth; 9 teeth on each anterolateral margin, the last tooth much larger than preceding teeth. Larger chela with conical tooth at base of fingers; pollex ridged. Color: carapace dull green to brown.
Minimum depth assumed from its ecology. Shallow waters up to depths of 50 m. Inhabits sandy to sandy-muddy substrates (Ref. 343). Benthopelagic predator, feeding mainly on bivalves (Lamellibranchia), benthic crustaceans, fishes and cephalopods (Ref. 117071).
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.
