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.

There have also been revolutionary findings concerning phylogenetic relationships, such as the hypotheses that extinct placoderms may be paraphyletic, that the Holostei are again monophyletic, that elopomorphs rather than ...
The taxa are always intended to be monophyletic (i.e., clades), but in many cases future research may show that they are not, and the classification must be modified accordingly. The categories used, and their endings in parentheses ...
Among extant taxa, the Cephalochordata and Craniata form a monophyletic group according to most authors (e.g., Cameron et al., 2000; Halanych, 2004) but some (e.g., Lowe et al., 2015) place Urochordata closest to Craniata.
However, there is an alternative hypothesis, termed the “cyclostome hypothesis,” which holds that lampreys and hagfishes are monophyletic together and sister groups to each other. The latter grouping is an old idea that was discarded by ...
(vertebrates). The following taxa, placed within six superclasses, are recognized here in the Vertebrata following Donoghue et al. (2000). This monophyletic group contains members possessing or inferred to be derived from ancestors with.
