Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 2.0 cm TL male/unsexed; (Ref. 80376); 1.75 cm TL (female)
Maximum depth from Ref. 97531. Found on rubble (Ref. 97531). Lives in reef edges near tide level and associated with rocks and coral, e.g., Pocillopora and Porites (Ref. 79713), Acropora, Siderastrea and Mussismilia spp. (Ref. 80376). Specifically found in nodules and cavities of calcareous algae, in sponges, in branching dead and living portions of corals in reef edges near tide levels (Ref. 79713). Capable of excavating cavities using its major claw and can excavate tunnels into the coral Mussismilia or into coral's epibiotic growth consisting of coralline algae, ascidians and bryozoans (Ref. 80376). Lives in male/female pairs (Ref. 79713).
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.
