The population characteristics of three species of demosponges (Mycale sp., Verongia gigantea, and Tethya crypta) inhabiting the waters near Discovery Bay, Jamaica, are inspected, including habitat distributions, biomass densities, size-frequency distributions, growth rates, mortality rates, and reproduction. The three species are compared to show that major differences do exist in their ecological roles as well as in their strategies of energy utilization. The factors effective in limiting local distribution in sponge species are discussed with reference to the species studied here and to the members of the phylum in general.
