Fourth segment (merus) of larger claw (cheliped) with serrated tooth and ridge on lower margin; fifth segment (carpus) in male shorter than broad; sixth segment (propodus) excavate and with minor tooth in gape; fixed finger straight; last segment(dactylus) irregularly dentate, more so in male. Tail fan (telson) longer than wide, as long as uropods. Body white, tinged with red, up to 8 cm long.
All ghost shrimps are burrowers, either making complex tubular branching burrows in muddy and sandy sediments or living in crevices under rocks and corals. This burrowing behaviour make them an important part of the marine environment. During feeding and burrow construction, they are continuously processing the sediment causing mixing and transportation of particles and gases. Each species creates a unique burrow plan which in turn has a different effect on the sediment and nutrient dynamics of the system. The presence of burrows ultimately increases the oxygen content of the sediment leading to a healthier system.
Intertidal and shallow subtidal mudflats and sandy beaches, to 13 m depth.
Southern temperate oceans, including southern Australia.
