FEEDING PREFERENCES AND RATES OF THE SNAIL, IANTHINA PROLONGATA, THE BARNACLE, LEPAS ANSERIFERA, THE NUDIBRANCHS, GLAUCUS ATLANTICUS AND FIONA PINNATA, AND THE FOOD WEB IN THE MARINE NEUSTON
On the afternoon of November 5, 1965 during strong north-northwest winds, Porpita, Velella, Physalia, G!aucus, Lepas, Fiona, and three species of Ianthina were blown onto the north beach of the Seto Marine Biological Laboratory. In the Laboratory with an ample supply of running sea water, many of these animals lived for several days and I was able to observe their feeding preferences and rates. On the basis of these obervations and the reports of other workers it is possible to construct a preliminary diagram of the neuston food web.
