ANDHRA PRADESH : Visakhapatnam (Waltair)— Ganapati & Rao (1967) , Rao & Ganapati (1968a) ; ODISHA ( Orissa ): Puri—Rao (1989); ANDAMAN & NICOBAR ISLANDS : Mayabandar—Rao (1975, 1980b); LAKSHASDWEEP: Agatti, Bangaram—Rao (1991); WEST BENGAL : Medinipur—Sanyal (2012); GENERAL RECORD—Rao (1972), Naidu & Rao (2004) , Rao (2005) . Habitat (as in Indian records). Coarse sand with fine shell gravel and a little detritus in the intertidal zone near half tide level. Distribution. Widespread species, recorded from numerous areas and localities outside the type locality (off Castel dell’Ovo, Naples, Italy ); these include West and East Mediterranean Sea, North Europe, British Islands, Bermuda , USA (Atlantic and Gulf coasts of Florida ), Caribbean Sea, Brazil , Red Sea, Maldives , Somalia (as U. cf viviparus ) and India . Remarks. The species has been found at different depths (from littoral to 33 m ) and in sediments of various grain size in general rich in organic detritus. A recent phylogenetic analysis of the genus Urodasys based on a molecular genetic data found specimens of U. viviparus from geographic distant populations (e.g., Cayman islands and Brazil ) clustering together, testifying to their common origin (Atherton & Hochberg 2015 ).
