Coleman's shrimp pair on a fire urchin

Coleman's shrimp pair on a fire urchin, originally uploaded by echeng.

Coleman’s shrimp (Periclimenes colmani), a beautiful commensal shrimp that lives in pairs on fire urchins (Asthenosoma varium), are fairly common in Ambon. Fire urchins are typically found here at depths of 60-90 feet, and about one out of 20 will have at least one of three kinds of commensal crustacea living on them.

Using the INON insect eye lens (Underwater Micro Semi-Fisheye Relay Lens UFL-MR130 EFS60), I was able to capture two Coleman’s shrimp in a valley of fire urchin spines. Shots taken with traditional lenses cannot capture the colorful environment in which these shrimp live.
