Description

Also known as Crustaceans, Carid Shrimps, Commensal Shrimp, Fire Urchin Shrimp, Sea Urchin Shrimp and Toxic Urchin Shrimp.

Found usually in pairs exclusively on the fire urchin -Asthenosoma varium, which in turn is known as the toxic sea urchin. The larger one is the female. The host urchin's spines do not harm the shrimp, but they usually clear an area on the urchin where they perch.
They feed on parasites, algae and plankton.
Length - 2cm
Depth - 5-30m
Widespread West Pacific

Often if a divers hand is near to a cleaner shrimps, they will hop on board and perform a manicure!
Not that I would recommend doing that with this shrimp!!

Carid shrimps occur worldwide in almost every habitat, from sea water to fresh water and can be found all over the reef.
They are generally respected by other creatures, often sharing burrows and holes and working as housekeepers.
They will wave their antennae around to attract customers, they then proceed to clean outside and inside the creatures mouths, gills etc,. Ref: http://aquaviews.net/explore-the-blue/marine-life-identification-types-of-shrimp/
