Fatty acid composition and the classification of the Porifera

Investigation of the fatty acid profiles of 55 species of Porifera has confirmed the occurrence of high percentages of both long chain fatty acids (C 24-C 30) and polyunsaturated acids. These features of the fatty acid profile in conjunction with the content of branched chain acids and the dominance...

Summary:Investigation of the fatty acid profiles of 55 species of Porifera has confirmed the occurrence of high percentages of both long chain fatty acids (C 24-C 30) and polyunsaturated acids. These features of the fatty acid profile in conjunction with the content of branched chain acids and the dominance of particular acids in different species allow some systematic discussion. The Dictyoceratida, Clathriidae, Halichondrida, Homoscleromorpha and Calcarea are distinguished by aspects of their fatty acid profiles. The diversity in number and type of sponge fatty acids exceeds that of any other phylum. Environmentally induced variation in fatty acid content is such that percentage compositions alone have little taxonomic informational value.
