Book Description
Рассмотрены систематика и распространение живоглотовых рыб рода Pseudoscopelus. Тринадцать видов этого рода признаны валидными, из них два (P. albeolus Prokofiev et Kukuev и P. vityazi Prokofiev spp. n.) описаны как новые, хотя можно предполагать существование большего количества еще неописанных видов. P. albeolus sp. n. представляется близко родственным надвиду “P. astronesthidens”, но отличается от всех известных видов рода однотонно белесой окраской тела и фотофоров. P. vityazi sp. n. представляется наиболее близким к P. altipinnis, но отличается от всех известных видов рода наличием желобообразных полос светящейся ткани вместо серийных фотофоров. Номинальный род Myersiscus Fowler, 1934 является синонимом Pseudoscopelus, а вид P. microps Fowler, 1934 синонимизирован с P. altipinnis Parr, 1933. Обсужден статус недавно описанного P. pierbartus Spitz et al., 2007; он признан species inquerenda и nomen dubium, но, по-видимому, является синонимом P. scriptus или P. sagamianus. Рассмотрены изменчивость и диагностическая значимость признаков, важных для выделения видов Pseudoscopelus. Дан ревизованный ключ для определения видов.

Book Description
Take your knowledge of fishes to the next level Fishes of the World, Fifth Edition is the only modern, phylogenetically based classification of the world’s fishes. The updated text offers new phylogenetic diagrams that clarify the relationships among fish groups, as well as cutting-edge global knowledge that brings this classic reference up to date. With this resource, you can classify orders, families, and genera of fishes, understand the connections among fish groups, organize fishes in their evolutionary context, and imagine new areas of research. To further assist your work, this text provides representative drawings, many of them new, for most families of fishes, allowing you to make visual connections to the information as you read. It also contains many references to the classical as well as the most up-to-date literature on fish relationships, based on both morphology and molecular biology. The study of fishes is one that certainly requires dedication—and access to reliable, accurate information. With more than 30,000 known species of sharks, rays, and bony fishes, both lobe-finned and ray-finned, you will need to master your area of study with the assistance of the best reference materials available. This text will help you bring your knowledge of fishes to the next level. Explore the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships of fishes Access biological and anatomical information on more than 515 families of living fishes Better appreciate the complexities and controversies behind the modern view of fish relationships Refer to an extensive bibliography, which points you in the direction of additional, valuable, and up-to-date information, much of it published within the last few years Fishes of the World, Fifth Edition is an invaluable resource for professional ichthyologists, aquatic ecologists, marine biologists, fish breeders, aquaculturists, and conservationists.

Book Description
This book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the singlecelled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution. The book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

Book Description
This enlightening new volume details over 200 species of bioluminescent marine fishes along with their biotechnological and therapeutic applications. It delves into the chemistry, diversity, biology, and functions of these fishes. Bioluminescence, which is a type of chemiluminescence and is a "cold living light," is seen in a wide variety of organisms from bacteria to fish. The chemicals and circumstances of this phenomenon are used for biotechnological, commercial, and therapeutic applications. Bioluminescence imaging technology has provided valuable means for the monitoring of different biological processes for immunology, oncology, virology, and neuroscience. A new emerging biological technique that combines luminescence with optogenetics involves the use of light to control cells, particularly neurons, in living tissue. Bioluminescence may also be as a potential form of green energy. The author states that more than 75% of deep-sea creatures (700 marine genera within 16 phyla) have been estimated to possess this phenomenon of bioluminescence. While marine plants do not display bioluminescence, several organisms such as the dinoflagellate, cnidarian, jellyfish, ostracod crustacean, molluscan squids and lantern fish are well known for their luminescence. Bioluminescence is employed by marine organisms mainly to hunt their prey, to defend against predators and in reproduction. This scientifically comprehensive and well-illustrated book will serve as an essential standard reference for students and teachers as well as marine biologists, fisheries scientists, zoologists, and environmentalists.

Book Description
This comprehensive guide encompasses a total of 473 species of mesopelagic fishes (i.e. those fishes residing primarily between 200 and 1 000 m depth during daytime) that are known to occur in the western Indian Ocean. It aids in their accurate identification, offering dichotomous keys to all taxa. Species are treated in detail, with accounts including the scientific name, FAO common name in English (where available), other useful characters, size, a distribution map, and one or more illustrations. Captions and arrows enhance user-friendliness for to both specialists and non-specialists in the field of ichthyology. In the broader context of marine ecology, mesopelagic fishes hold a pivotal role as integral components of the marine food web, serving both as predators and prey for various species. This guide not only enriches our understanding of these fishes but also contributes to our knowledge of the western Indian Ocean's diverse ecosystem. Beyond species identification, it sheds light on the interconnectedness of marine life and underscores the importance of conservation efforts in safeguarding this delicate balance. This guide serves as an invaluable resource for in-depth exploration and research into these remarkable fishes, offering a comprehensive tool for studying their diverse characteristics, behaviours, and ecological significance, essential elements for sustainable management and conservation practices.
