Shrimp are found in association with many hosts (sponges, anthozoans, mollusks, echinoids, ascidians and fish). At present, few published records exist concerning association of crustaceans with jellyfish. Jellyfish was carrying shrimp in subumbrellar surfaces. Only a few species of the genus Periclimenes have previously been observed in association with scyphozoan jellyfishes.Shrimps are rarely found associated with jellyfish and their interaction is poorly known. The association IS facultative commensalism, since the shrimp gain protection and probably feed on mucus produced by the jellyfish.
