Book Description
The family includes 86 species in 17 genera. Species are characterized and most of them are illustrated. Summaries of biological studies pertinent to classification are included. Keys to genera and species are provided. Six new species and one new subspecies are described: Parmaturus manis of the western North Atlantic; P. stenseni of the Pacific continental slope off Panama; P. campechiensis from the Gulf of Mexico; Galeus schultzi from Philippine seas; G. arae antillensis from the West Indies; and two species of Apristurus from the western Atlantic, A. canutus Springer and Heemstra and A. parvipinnis Springer and Heemstra. Two populations close to Galeus arae and one population close to G. melastomus are treated here as subspecies; they are G. a. antillensis (new subspecies) and G. a. cadenati of the Caribbean region and G. m. murinum of northeastern Atlantic island slopes. Treatment emphasizes descriptive accounts thought to be useful for species identification.

Book Description
"Abstract: The catshark genus Scyliorhinus belongs to the family Scyliorhinidae, the most diverse family of sharks, and currently presents 16 valid species according to most modern accounts. The long history of taxonomic rearrangements and inaccurate descriptions of many species have contributed to misidentification of specimens and lack of information on the distributional range and diagnostic characters of its species. Species of Scyliorhinus are reviewed and redescribed here, with detailed descriptions on external morphology, neurocranium, claspers, dermal denticles, and tooth morphology provided for the first time for all species. Sixteen species are recognized as valid: Scyliorhinus boa (Goode & Bean, 1896), S. cabofriensis Soares, Gomes & de Carvalho, 2016, S. canicula (Linnaeus, 1758), S. capensis (Müller & Henle, 1838), S. cervigoni Maurin & Bonnet, 1970, S. comoroensis Compagno, 1988, S. duhamelii (Garman, 1913), S. garmani (Fowler, 1934), S. haeckelii (Miranda Ribeiro, 1907), S. hesperius Springer, 1966, S. meadi Springer, 1966, S. retifer (Garman, 1881), S. stellaris (Linnaeus, 1758), S. torazame (Tanaka, 1908), S. torrei Howell-Rivero, 1936, and S. ugoi Soares, Gomes & Gadig, 2015. The main taxonomic decisions herein taken include the resurrection of S. duhamelii (previously a junior synonym of S. canicula) and the synonimization of S. tokubee with S. torazame. Information on geographic distribution was updated for most species, especially for those with wide ranges (S. canicula, S. haeckelii, S. retifer, and S. stellaris).

Languages : en
Pages : 1128
Book Description
The Gulf of Mexico is the ninth largest body of water in the world and contains over 15 percent of all known species of marine fishes. This diverse fish fauna has been the subject of many publications, but, until now, no work has ever surveyed all known species, including the deep sea fishes and those of the southern Gulf. This book is the first of two volumes that will cover the entire fish fauna of the Gulf of Mexico. An introductory section that outlines the Gulf's geographical setting, geological origin, current patterns, tides, sediments, meteorology, ecology, and biological exploration is followed by a key for the forty-four orders of fishes known from the Gulf. Keys and descriptions are provided for families, which are arranged phylogenetically, and for the species, which are arranged alphabetically, described, and distinguished from similar species. All but a few species are illustrated.
Deep-Sea Fishes

Book Description
The deep ocean is home to some of the most unusual of all fishes. This book is the first Fish Physiology volume devoted to these bizarre undersea creatures. Practically every organ system is affected by the constraints imposed by benthic pressure, the absence of light, and the relatively scarce supply of both food and mates. Deep Sea Fishes demonstrates how these fishes living in extremely harsh conditions metabolize, behave, and evolve.
The Teeth of Non-mammalian Vertebrates

Pages : 544
Book Description
The Teeth of Non-Mammalian Vertebrates: Form, Function, Development and Growth, Second Edition is devoted to the teeth and dentitions of living fishes, amphibians, and reptiles. This book presents a comprehensive survey of the wide variety of tooth forms among non-mammalian vertebrates, based on descriptions of approximately 450 species belonging to about 170 families.This latest edition discusses the functional morphology of feeding, the attachment of teeth, and the relationship of tooth form to function, with each chapter accompanied by a comprehensive, up-to-date reference list. Following the descriptions of the teeth and dentitions in each class, four chapters review current topics with considerable research activity: tooth development; tooth replacement; and the structure, formation, and evolution of the dental hard tissues. The Teeth of Non-Mammalian Vertebrates: Form, Function, Development and Growth, Second Edition is authored by internationally recognized teachers and researchers in the field. This new edition reflects the resurgence of interest in the dentitions of non-mammalian vertebrates as experimental systems to help understand genetic changes in evolution of teeth and jaws. Features more than 650 images, including photographs from internationally recognized researchers and world class collections Offers in depth information on tooth structure, development, attachment, and replacement Provides detailed descriptions of the dentitions of all living groups of non-mammalian vertebrates Discusses the relationship between tooth form and structure to function in the feeding process
