‘Hitchhiker’ polynoid polychaetes in cold deep waters and their potential influence on benthic soft bottom food webs
Abstract We describe a new association for Antarctica, involving an holothuroid host, Bathyplotes bongraini Vaney, 1914, and a parasitic polynoid polychaete, Eunoe opalina McIntosh, 1885, which lives on the host body. Both species have never been recorded in the study area, the Ross Sea. The ecologi...
