| Abstract |
The particular difficulties of the taxonomy of calcareous sponges are due to their great plasticity and their capacity for adaptation which obscure the natural limits of species. An attempt was made to define the natural populations of the Mediterranean species of the generaClathrina andAscandra through a study of their ecological distributions. The populations not connected by the transitory forms were defined by their ecological preferences, and, as they are found in a close cohabitation, were treated as having the specific values. The variability of different morphological features is discussed, the features significant for taxonomy are pointed out and the morphologically close species are defined. |
