This brilliant colour is caused by IIV-31 (Isopod Iridescent Virus). I've been checking hundreds of pill bugs over several years for this unusual phenomenon and my persistence finally paid off!

A green chiton attached to a half crab. We observed this alien looking commensal beast while undertaking an intertidal survey on the reefs off Hawera. It made us jump when we first turned over the rock.
