Sponges are among the simplest of multicellular animals and are often described as the most primitive of all. Study of sponge lipids is as important as other secondary metabolites and has been well documented in a series of extensive reviews by Berge and Barnathan, Rod′kina, etc. [1,2]. Regular research into lipids of sponges began in the 1970s  and continues till today because they have the greatest diversity of fatty acids, sterols etc. Studies on fatty acids and sterols as lipid components of sponges and other organisms have been elaborately taken up by a number of investigators [4,5].
