Preliminary observations on the influence of water movement on population structure in Ancorina corticata (Carter) (Choristida: Demospongiae).

The influence of water movement on sponge population structure was investigated in the marine sponge Ancorina corticata (Carter) from Westernport Bay, Victoria, Australia. Population characteristics studied were dispersion, population density, biomass and size-frequency distributions. Strong continuous water movement facilitated the growth of the sponge but no effects were found on the dispersion patterns of the population
