ANDREA AND ANTONELLA FERRARI have spent years amassing the photographs and information contained in A Diver's Guide to Reef Life, and it shows.
With 1200 tropical species, ranging from coral polyps, gorgonians, sea squirts, sponges, nudibranchs and all of the main fish groups, this is a truly comprehensive work, and probably the only reef guide most divers will need to take with them on a trip.
Covering the Red Sea, Indo-Pacific and many Caribbean species, the book comes in a handy, almost square format with just three species per page, allowing good-sized images of high quality.
The authors describe each species carefully, and where possible give information on behaviour to assist with identification. For example, the reader learns that the orangeband surgeonfish (Acanthurus olivaceus) 'can switch its main body colour from dark olive to tan to dark blue in seconds' and that there are 40 different species of triggerfish. One section shows juvenile specimens of some of the commonest fish, demonstrating how unlike their adult forms they can be.
Photographically, Reef Life is excellent, with every shot a genuinely representative view of the animal or fish described. The book also contains a good general introduction to coral-reef ecology, and titbits of information are spread throughout the text: '94 million tonnes of fish are now taken globally each year, compared to 19 million tonnes in 1950.'
The Ferraris also produced the Macrolife Guide to Underwater Malaysia, in my opinion the best of its kind. Now they have created an indispensable companion volume that will serve every diver well.
