Biology

Sand shrimps differ from all other caridean shrimps in having flat short chelipeds ending in a finger fitting across an oblique palm (rather than having two extended opposing fingers). All sand shrimps live on sandy sediments offshore but are so well disguised that they are rarely seen. This is the most common sand shrimp species encountered in sheltered environments such as Port Phillip Bay and Western Port.

Distribution

Southern temperate oceans, including southern Australia.

Habitat

Subtidal and bay sediments, to 42 m depth.
