Synopsis Molluscs represent one of the largest and most diverse phyla in the entire animal kingdom. Next to the arthropods, they have the most named species in the animal kingdom. Molluscs both extinct and living compromise about 11 per cent of all animal species that have ever evolved during the entire course of earthy history. The diversity of the phylum is shown by the seven known classes, which are represented by the snails, mussels, oysters, clams, squids, octopuses and scallops. Although extremely diverse, the phylum is united by a common ground plan of anatomic and morphologic similarities. The name mollusca is derived from the Latin molluscus, meaning soft.

The book is designed so that selected parts can be used for graduate and post-graduate courses. The present book deals with the latest information about the phylum mollusca. The morphology, anatomy, reproduction and classification of the phylum is described in detail. It is expected to be a boost for the students as well as teaches and other learners.
