Three species, Bathynomus decemspinosus, B. doederleini and B. kensleyi （Crustacea, Isopoda, Cirolanidae）, are reported for the first time from the Parangipettai coastal waters, Southeast coast of India. Several Tri...Three species, Bathynomus decemspinosus, B. doederleini and B. kensleyi （Crustacea, Isopoda, Cirolanidae）, are reported for the first time from the Parangipettai coastal waters, Southeast coast of India. Several Trilasmis （Temnaspis） tridens （Cirripedia Thoracica, Lepadomorpha） were attached to the pleopods of some individuals. So, five bathynomid species are currently reported from India.展开更多
