Les Nudibranches ou Limaces de Mer se retrouvent dans tous les océans du monde et dans de très nombreux habitats marins. La plus grande diversité des espèces prolifère sous les tropiques de la région Indo-Pacifique, le "Triangle de Corail" (TC) comprenant les eaux territoriales de six pays d'Asie du Sud Est: l'Indonésie, la Papouasie, les Philippines, la Malaisie, Timor-Leste et les Iles Solomon. Cet épicentre global de la biodiversité marine ne couvre que 1,6% de la surface des mers de la planète mais elle attire un nombre toujours croissant de plongeurs et de photographes pratiquant ce sport sous-marin, parmi lesquels les amoureux des nudibranches. Ce livre est un guide de terrain, un assistant pour l'identification des espèces de Nudibranches de la région, spécialement publié à l'intention des plongeurs et des photographes en milieu sous-marin. On y trouve la référence de plus de 1060 espèces à découvrir et/ou à photographier dans les profondeurs et régions accessibles aux plongeurs et photographes pratiquant ce sport. Les photographies ont été prises à différents stades de maturité des espèces et mettent en valeur la variation des couleurs. Les noms des spécimens ont été vérifiés suivant le "World Register of Marine Species (WoRMS)".

Seashell or sea shells are the hard exoskeleton of mollusks such as snails, clams, chitons. For most people, acquaintance with mollusks began with empty shells. These shells often delight the eye with a variety of shapes and colors. Conchology studies the mollusk shells and this science dates back to the 17th century. However, modern science - malacology is the study of mollusks as whole organisms. Today more and more people are interacting with the ocean - divers, snorkelers, beachgoers - all of them often find in the seas not empty shells but live mollusks - living shells, whose appearance is significantly different from museum specimens. This book serves as a tool for identifying such animals. The book covers the region from the Red Sea to Hawaii, the Marshall Islands, and Guam. Inside the book: - Photographs of 1500+ species, including one hundred cowries (Cypraeidae) and more than one hundred twenty allied cowries (Ovulidae) of the region;- Live photo of hundreds of species have never before appeared in field guides or popular books;- 2600 full-color images;- Convenient pictorial guide at the beginning and index at the end of the book.It is designed for divers, underwater photographers, snorkelers, shell collectors, beachcombers, and nature lovers. Photographs, showing color variations are included. The validity of species names was checked with the help of the World Register of Marine Species (WoRMS).
