During regular suwey and inonitoring work on the jellyfish swanning along the Palk Hay coast of Pampan in 20 1 7, huge jellyfish species Rhopilo~zahisyidu~~z (Modachori in tanzil) were observed during sunln~er months and upon closer inspection of the specimens, there were numerous brittle stars associated with the oral side of the jellyfish, These speciinens were further studied taxoiloinically and identified as Ophiocnenzis n z a ~ ~ ~ z o r a t ~ .  Aniong the ten jellyfishes sampled, about 100 to 150 brittle stars were found in each jellyfish. This kind of association by the brittle stars is attributed for getting food, protection and a dispersal strategy by the brittle stars with jelly fishes. Interestingly, bsittle stars are particle feeders and steal the planktonic material available on the oral gelatinous side of the jellfish arid feed, This kind of relationship is tenned as 'Kleptoparasitism'. Brittle star an echinoderm was found to have association with jellyfish in the wild.
