Fish is a cold-blooded aquatic vertebrates usually having scales and breathing through gills. This specie is used for the study of the flexible behaviour of the vertebrates. For example- Zebra fish are used in the studies of gene expression.

According to the Ichthyology (branch of zoology that studies fishes), modern fishes are divided into three classes: 1. Agnatha (the jawless fishes); 2. Chondrichthyes (jawed fishes that possess skeletons made of cartilage; and sharks, rays, skates and ratfishes); 3. Osteichthyes (jawed fishes that have skeletons made of bone).
