Nudibranch (Risbecia tryoni) - PNG

Risbecia tryoni is often found "tail-gating" one another whereby one individual follows the mucous trail of another. The 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
