The Weed Shrimp is common but its coloration is an effective disguise. The colour varies depending upon the seaweed on which it lives; solidly bright green on green algae and deep red on red algae. They are probably algal browsers freely moving among their habitat. They usually walk on their legs but can use the strong muscular abdomen and tail fan combined to reverse the shrimp quickly out of danger. This behaviour is common to most caridean shrimps.
Subtidal to 124 m depth.
Southern temperate oceans, including southern Australia.
Small claws but unlikely to nip.
