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.

... concept of stem and crown groups. For any given taxon with extant members, the crown group is all those species descended from the last common ancestor (LCA) of all the extant members (see figure). Note that certain fossil taxa can.
... taxa can be members of the crown group. The stem group or stem-group taxa are all those extinct taxa known by fossils that are more closely related to this particular crown group than they are to any other extant clade. The Total Group ...
