A population of Cordylophora caspia was studied during a number of years in interconnected waters of different salinity and pollution. The distribution pattern of the colonies is only partly accounted for by these properties of the water. Part of it is also due to the availability of suitable substratum. Evidence is given that colonies of Cordylophora grow and survive on stones along the banks, but flourish during the summer on free-floating water-lily stalks.
