| Often found "tail-gating" each other. One individual follows the mucous trail of another. Reason for "tail-gating" is unknown, however, maybe a method of finding prey or a prelude to mating. Variation in colour and distribution of spots can differ between individuals The tube-like appendix is the animals sexual organs; exposed here before copulation Often found with Imperial Shrimp (Periclimenes impertor) which feeds on parasites and mucous whilst obtaining protection from predators.
