Marine Flatworms

The intriguing and colourful world of Polyclads - free-living marine flatworms.

Marine flatworms are some of the ocean's most beautiful of those creatures that can be encountered by divers, snorkelers or simply lovers of marine life under water or in the intertidal zone. They are relatively simple animals with soft flat bodies. In this book we will focus on the free-living highly diverse marine flatworms of the order Polycladida. Often confused with nudibranchs, they are falling under the completely different phylum platyhelminthes (Platyhelminthes, Greek "platy": flat; "helminth": worm.) The book covers the region from the Red Sea, East and South Africa to Hawaii, Marshall Islands and Guam. Inside the book: •Over 1300 full color photographs of 580+ species; • Particular attention was paid to color variations; • Live photo of hundreds of species have never before appeared in field guides or popular books; • Convenient pictorial guide at the beginning and index at the end of the book. • The book contains photographs of most of the recently described Indo-Pacific flatworms, some of them are represented by holotypes.

This practical and interactive CD-ROM is an essential resource for those who wish to identify the hundreds of species of conspicuous and colourful marine polyclads.

A layman's guide to identifying and understanding the marine life while scuba diving.

Nudibranchs of the Coral Triangle became the only guide to nudibranchs on the market with an up-to-date 2022 taxonomy after its major update (November 2022) This book is a field guide, an assistant for the identification of nudibranchs species in the region. It is designed for divers, underwater photographers. The book presents 1060+ species nudibranchs that can be found and photographed in depths and regions accessible to recreational diving. Photographs, showing color variations and age differences are included. A lot of species covered by this guide have never before appeared in field guides or popular books. Compact text blocks provide information about Common name, Latin name, family, geographic distribution, size, and the most distinctive features. An extensive photo index at the beginning of the book helps you to find the right group of nudibranchs, especially for readers who have not yet mastered their names. Nudibranchs or sea slugs occur throughout the world’s oceans and are present in many marine habitats. The greatest diversity of species is found in the Indo-Pacific tropics with a concentration of species within the Coral Triangle (CT), encompassing the waters of six Southeast Asian countries: Indonesia, Papua New Guinea, Philippines, Malaysia, Timor-Leste and Solomon Islands. This global epicenter of marine biodiversity covers only 1.6 percent of the planet’s oceanic area, but attracts an increasing number of divers and underwater photographers, including nudibranch lovers.

Marine Life of the Maldives is an identification guide for divers, snorkellers and beachcombers in the Maldives and wider Indian Ocean region. It includes all the main marine invertebrates, marine plants, mammals, reptiles and birds. The update of this popular book has been carried out by the associate authors after the death of author Neville Coleman in 2012. It includes a full revision of scientific and common names as well as a revision of the Phylum Cnidaria (Stingers), which includes the Stony corals. A comprehensive introduction outlines the main changes to the marine environment since the book was first published in 2000. Beneath the warm, clear waters of the Maldives lies a wonderful world of extraordinary sea creatures. In Marine Life of the Maldives – Indian Ocean this truly magnificent spectacle is captured in 344 pages of vivid photographs with authoritative text by one of Australia’s leading Marine Naturalists. Although this book is based on scientific classification, its primary function is to encourage greater awareness among divers on a level that everyone can understand. The text is informative and educational and illustrates almost every major group of marine invertebrates. It is supported by a full Glossary to explain references to scientific terms. By using this book as a guide, divers can recognize and understand more about the many creatures seen on the reefs and participate in their discovery. It provides the reader with an opportunity to explore previously unknown life forms and opens a whole new adventure into the world of marine invertebrates. Marine Life of the Maldives also provides teachers of marine biology with a useful reference for conducting marine courses and ecological surveys. First published in 2000 as Marine Life of the Maldives. Reprinted with corrections in 2012 as Marine Life of the Maldives, Divers and Snorkellers Guide. Published again in 2019 as Marine Life of the Maldives, Indian Ocean.

This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.
