The animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the subject of volume 3 in this series. It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproductive system and its components, is the subject of Part A. Part B deals with complementary topics: testes, sperm, and sperm competition; endocrinology of reproduction; pheromones and reproduction; copulatory structures: taxonomic overview and the potential for sexual selection; sexual selection: signaling and courtship; adaptation and evolution of reproductive mode in copulating cottoid species; fertilization; sex determination; parental care; reproduction in relation to conservation and exploitation of marine fishes; Cryopreservation of Gametes; Embryogenesis and Development; and Molecular Genetics of Development.

Richards
The book, part of the series Reproductive Biology and Phylogeny, is organized into 13 chapters, each written by respective experts. The chapters reflect a range of biological perspectives, including development, endocrinology, conservation, aquaculture, and ecology, and the different points of view create an overall appreciation for the utility of these animals in science and society. … This volume will be most useful to evolutionary ecologists, as it collects together excellent chapters on parental care, sexual selection, and sperm competition that both review and synthesize the literature.This evolutionary ecology focus is complemented by a deeper understanding of the physiological aspects of reproduction from several other chapters.
