Biology     Glossary (e.g. epibenthic)

Carapace width: 9.2 cm (Ref. 435). Sublittoral, typically burrows in inshore soft bottoms (Ref. 106272). Also burrows in sand at depths of 13 to 400 m, common at depths of 30 to 150 m (Ref. 435). Found on a variety of bottoms -- sandy, shell grit, hard rocks and coral (Ref. 106272). Reported on upper to middle slope as well as in a seamount (Ref.106167). Infaunal feeder preying on bivalves and foraminiferans (Ref. 52384).

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.
