This catalogue, which integrates nearly 35,000 records of benthic marine algae from the Indian Ocean into a taxonomic classification comprising 3,355 specific and infraspecific taxa in 629 genera, will greatly facilitate future work in this region. The bibliography of 4,000 references is the largest list of phycological literature ever published. The extensive taxonomic and nomenclatural notes are of paramount importance.

This guide, illustrated by more than 1,500 underwater photographs, presents nearly 1,200 species of fish in the Indian Ocean and Red Sea. The reference work dedicated to enthusiasts of the undersea world, more especially divers, will also be of interest to a wide audience that is curious about Nature and its riches.
