Abstract
    Previous studies on sponges and other invertebrates have suggested that acid mucopolysaccharides (AMPs) may be of possible use in taxonomy. Thus Stempien (1966) suggested that the composition and localization of AMPs within sponge tissues may be of use in resolving some of the complex taxonomic problems within this group. More recently,. rahemtulla and Lovtrup (1975 b) have suggested that the distribution of particular AMPs within various invertebrate phyla may be used as a basis for establishing phylogenetic relationships. With these earlier studies in mind, the nature and cytological localization of AMPs within a wide range of Demospongiae were examined in detail in an attempt to establish a firm basis for any possible role of AMPs in taxonomy within this class of sponges. Analysis of AMPs by the electrophoretic and histochemical procedures employed in this more extensive study, however, failed to yield evidence supporting the existing hypotheses. The type and localization of AMPs are thus not considered to be valid taxonomic parameters within the Class Demospongiae.
