"Pelagic Snails" is a book that I acquired infrequently after it became unavailable in print. The book serves as a comprehensive biological study, focusing on the 140 known species (at the time of publication) of these remarkable mollusks. Unlike other gastropods we are familiar with, these snails spend their entire lives drifting on or near the ocean's surface, nourishing themselves with plankton. To adapt to their unique environment, they have developed several distinctive traits not observed in other mollusks. The book is well-written and offers in-depth insights into the biology of these peculiar creatures. Additionally, it features numerous photographs, showcasing several species for the first time. With a total of 99 half-tone illustrations, 55 line drawings, 16 color photographs, and 25 descriptive tables and text, the book provides a visually rich and informative experience.
The copy I possess is from a library and is in excellent condition. The book's body appears new, and its dust jacket is safeguarded by a clear plastic cover. It bears a library catalog number on the spine, a card pocket on the back flyleaf, and a barcode label on the inside back cover. Furthermore, the edges of the book are stamped with the originating library's name.
