生物學特性     字彙 (例如 epibenthic)

Usually found in eelgrass beds (Ref. 128717). Maximum carapace width: 7.7 cm; commonly 5 cm wide. Inhabits shallow water from the intertidal area down to 200 m. Lives under stones, on muddy or muddy sand bottoms, or hard bottom, etc. Also inhabits brackish lagoons (Ref. 2779), and eelgrass beds (Ref. 128717).

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚

Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833). Berried females migrate from littoral areas to more saline and deeper water (8-10 m) until hatching of eggs; afterwhich, they go back to moult and copulate (Ref. 128197). Larger females can breed twice or thrice annually (Ref. 128203).
