Are you a biological sciences researcher? If you are, then this book is for you. Authors Joseph S. Nelson, Terry C. Grande and Mark V. H. Wilson, have written the fifth edition of an outstanding book that is intended to provide a broad reorganization reference for fish systematics and classification. Authors Nelson, Grande and Wilson, begin by considering it desirable to maintain the fish diversity that systematists study, and systematists can play a leading role in protecting this diversity. In addition, they explain how the phylum Chordata, has been used by most modern workers to encompass members of the subphyla Urochordata, Cephalochordata, and Craniata. The authors also discuss how the notochord of cephalochordates extends to the anterior end of the body, anterior to the brain. Then, they continue by discussing how Conodonts were diminutive, eel-like animals with a dental apparatus of many distinctively shaped, phosphatic, tooth-like structures arranged in an intricate pattern of paired and unpaired elements. The authors then cover how the term cyclostome is sometimes used for the living jawless fishes; this group is considered by most paleontologists and others using morphological evidence to be paraphyletic. Next, they discuss how Hagfishes are unique among craniates in having only one semicircular canal, which is orientated so that it projects onto all three planes of rotation. In addition, the authors describe how many of the earliest vertebrate remains are known from isolated microfossils such as scales and teeth. They also discuss how Lampreys are either parasitic or nonparasitic, and both life-history types characterize individuals of closely related species. Next, the authors explain, as with many fossil groups, especially the agnathans, it must be remembered that many character states are poorly known or inferred. In addition, the authors also cover how Thelodonts are known primarily from isolated micromeric scales, important for stratigraphic correlations, although many near-complete body fossils are known. Then, they continue by discussing how the Osteostracomorphi are now considered to be the sister group to the jawed vertebrates by many researchers. The authors then cover how in the fossil record, placoderms appear in at least the mid-Silurian and acanthodians appear in the Early Silurian, but in both cases the oldest fossils are fragmentary remains; scales and denticles attributed to chondrichtyans are doubtfully reported from the late Ordovician. Next, they describe that within the Eugnathostomata, the Chondrichthyomorphi are the sister group of the Grade Teleostomi and contain one class, Chondrichthyes. In addition, the authors describe how the two classes: the Acanthodii and Osteichthyes, account for the remaining vertebrates and have often been thought to form a monophyletic group termed the Teleostomi. They also cover how the subclass Actinopterygii, one of the major vertebrate taxa, is not diagnosed by strong derived character sets, but is nevertheless thought to be monophyletic. Then, the authors continue by discussing how it is generally agreed that the neopterygian fishes, are a monophyletic group. Finally, they then explain how when an attempt is made to date phylogenetic events, the molecular studies often postulate anomalously early lineage splitting times, such as the origin of Hiodontiformes by the end of the Paleozoic.
