    Marine micro- and macroorganisms are well known to produce metabolites with high biotechnological potential. Nearly 40 years of systematic prospecting all around the New Caledonia archipelago and several successive research programs have uncovered new chemical leads from benthic and planktonic organisms. After species identification, biological and/or pharmaceutical analyses are performed on. This revision attempts to bring the book taxonomically up to date as of October In addition, errors have been corrected, photos improved, new information incorporated, and several species added. -Replace Order Haplosclerida(?) with Order Dendroceratida sometimes occurs on boulders in shallow water close to shore. p. 19 HYDROIDS.

It is an almost indisputable fact that the shallow water sponge diversity is subjected to temporal variations taking place in their environments (Burton, ; Sara, ), which will be the major reason in the species variation among the Zones and seasons.

Our study also indicated the seasonal influence over the sponge populations. Shallow-water Niphatidae (Haplosclerina, Haplosclerida, Demospongiae) from the São Sebastião Channel and its environs (tropical southwestern Atlantic).

The Haplosclerida have long been recognised as a highly diverse group and this is clearly demonstrated in this study. Suggestions of the polyphyletic nature of the various taxa within haplosclerids have been appearing in various publications since [5], [9] – [11], [24], [59] with 18S, partial 28S rRNA genes and mitochondrial data.

Five species are new and two species are reported for the first time from New Caledonia. Nine previously described species were also found in this study and extra characters are reported, or additional locality and habitat records provided.

The new species belong to the Haplosclerida. This book is an outcome of the "Sponge Workshop" held at Sherkin Island Marine Station from th September, The Workshop was organized by Miss Shirley M.
