Echeneid–sirenian associations, with information on sharksucker diet
Abstract:Association of the sharksucker Echeneis naucrates and whitefin sharksucker E. neucratoides with the West Indian manatee Trichechus manatus and the dugong Dugong dugon is presented and discussed. Alimentary tract-content analysis and field observations suggest that coprophagy (feeding on host faecal material) may be the primary food source for echeneids associated with sirenian hosts.
