Vertebrate evolution has led to the convergent appearance of many groups of originally terrestrial animals that now live in the sea. Among these groups are familiar mammals like whales, dolphins, and seals. There are also reptilian lineages (like plesiosaurs, ichthyosaurs, mosasaurs, thalattosaurs, and others) that have become sea creatures. Most of these marine reptiles, often wrongly called "dinosaurs", are extinct. This edited book is devoted to these extinct groups of marine reptiles. These reptilian analogs represent useful models of the myriad adaptations that permit tetrapods to live in the ocean. Key Features * First book in more than 80 years devoted exclusively to fossil marine reptiles * Documents the most current research on extinct marine reptiles * Prepared by the world's most prominent experts in the field * Well illustrated

A comprehensive marine life identification guide on the Maldives in particular, and the Indian Ocean in general, with over 1000 colour photographs. It covers a wide range of the most commonly seen invertebrates and illustrates the extraordinary diversity and colour of the natural environment of the Maldives. It should be useful as a reference for scuba divers, reef walkers and snorkellers, as well as for aquarists and students of marine biology and natural history.
INTRODUCTION TO MARINE BIOLOGY distinguishes itself from other texts at this introductory level by taking an ecological approach to the study of marine biology, by providing succinct coverage of key topics, and through the use of the best illustrations and photos currently available. In this edition two co-authors have joined George KarleskintJames Small from Rollins College in Winter Park, Florida, and Richard Turner from the Florida Institute of Technology. Their experience in coastal environments nicely compliments Karleskint's clear, concise student-friendly writing style. Users will also discover that the level of the text has been broadened with additional coverage of plant, microbial, planktonic, and animal biology. In support of this emphasis, new "In Perspective" summary tables have been added to each of the marine organism chapters to provide a summary of important ecological and biological aspects of various marine organisms. Even with this broadened emphasis, this edition of INTRODUCTION TO MARINE BIOLOGY remains exceptionally readable. The textual material has been broken into small paragraph sections with more headings for ease of navigation, and "In Summary" statements have been added to the end of each main heading within the chapter, making it easy for students to check their understanding before reaching the end of the chapter. Furthermore, the authors have added more words to the glossary, many new illustrations, and over one hundred new photos. This second edition also boasts an increased "ecological focus" through the addition of discussions on "ecological roles and relationships."
This comprehensive introduction to the history of life on Earth explores the basic principles and processes, the rich history of past life forms -- marine and terrestrial -- and the major events that shaped this history. Emphasizes the complexity and diversity of life through time. Considers the causes for major events in Earth history --and weighs various interpretations. KEY TOPICS: Some of the many topics covered are: the organization of life, rocks and fossils, origins of the earth, oceans, atmosphere, and life, organic evolution and extinction, .marine predators, .early and advanced consumers on land. The book minimizes the use of technical terms, while providing to the reader short chapter-end lists of important key words and defines each term in a glossary.
