Comparative Morphometry, Biochemical and Elemental Composition of three Marine Sponges (Petrosiidae) from Gulf of Mannar, India

Posted on 30. September, 2010.

Sponges (Porifera) are the most ancient metazoans with ubiquitous benthic distribution. They are distributed along all latitudes from intertidal to deep-sea.  Many sponge species produce toxic substances enabling their survival in competitive marine environments. Some of the metabolites have beneficial pharmaceutical effects for humans with anti-inflammatory, cytotoxic, antitumor, antibiotic and anti-viral activities (Scheuer, 1978-1983; Faulkner, 1984; Uemura et al., 1985; Kim et al., 1998; Gunasekera et al., 1990).
