Zebra crab (Zebrida adamsii) on a sea urchin. This crab lives in a number of species of urchins. Here, it is on a false fire urchin (Astropyga radiata). The crab hooks itself in place with a pair of modified legs and feeds on the detritus from the urchin's round anus (partially seen at right). Photographed in Lembeh Strait, off Sulawesi, Indonesia.
