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.

The tadpole larvae of tunicates possess gill slits, dorsal hollow nerve cord, notochord, and a muscular, unsegmented tail; the adults are usually sessile filter feeders and usually lack the preceding features.
... the urochordates): notochord present (at least in embryo), a dorsal tubular central nervous system, paired lateral gill slits (at least in embryo), postanal tail, hepatic portal system, and endostyle (homologous with the thyroid).
... vertebral centra never present (only the notochord); gills covered with endoderm and directed internally; gill arch skeleton fused with neurocranium, external to gill lamellae; gills opening to surface through pores or a single pore ...
... external gill openings; adenohypophysis with undifferentiated cellular elements, not divided into distinct regions (unlike in vertebrates); hypoglossal nerve absent (represented by separate, segmentally arranged, anterior spinal ...
The external nasohypophyseal opening is terminal, and it is through this opening that respiratory water passes ... Subfamily Eptatretinae Efferent branchial ducts open separately to the exterior with 5–16 external gill openings.
