A note on the obligate symbiotic association between crab Zebrida adamsii White, 1847 (Decapoda: Pilumnidae) and Flower Urchin Toxopneustes pileolus (Lamarck, 1816) (Camarodonta: Toxopneustidae) from the Gulf of Mannar, India

The association of Parthenopid crab Zebrida adamsii and flower urchin Toxopneustes pileolus is reported for the first time from Gulf of Mannar. The Parthenopid crab Zebrida adamsii has been found to be associated exclusively with these sea urchins and this obligatory association has been studied by introducing another host sea urchin Salmacis virgulata to understand host preferences.
