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.

Nelson was cautious, especially about new taxa. His compromise was to discuss what he considered to be a radical proposal, such as that of the Neoteleostei by Rosen (1973), but not incorporate it into his classification.
Taxa (singular taxon) are groups of organisms recognized in a classification and given biological names (e.g., Salmoniformes, Salmonidae, Oncorhynchus, Oncorhynchus nerka). A category is the level or rank at which the taxon is placed ...
However, we can answer many critical questions of interrelationships of higher taxa only with the assistance of the fossil record and not, conclusively at least, from extant material only. Many important fossil taxa are ranked along ...
The following are examples of major taxa that are part of the classification but for which no formal rank is assigned: Vertebrata, Neoteleostei, and Acanthomorpha. This edition, like earlier editions, adopts a simplified classification ...
In some larger taxa, we use the term “basal” or “most basal” when referring to the lineage, usually of low diversity, that is sister to all others in the group. Some call these more basal lineages “early-branching lineages.
