periclimenes imperator

Hitchhiker by JimChen2 The Emperor Shrimp (Periclimenes imperator) looks really beautiful – yellow, white, purple and red colouration and its commensalism. The Emperor Shrimp can be found on several species of Sea Cucumbers and Nudibranchs. Usually they pick relatively big nudibranchs. Emperor Shrimps can be up to 30mm in size and always stay on their host.
