Feeding strategies and diet composition of four Antarctic cnidarian species
8 pages, 6 figures, 1 table The diet of four species of Antarctic cnidarians, two hydroids and two anthozoans, was investigated. One hydroid, Tubularia ralphii, and one anthozoan, Anthomastus bathyproctus, seem to basically consume zooplankton whereas the other hydroid species, Oswaldella antarctica...
