Fish Classification and Characteristics

This video from Mumu Math and Science discusses the classification of fish into three main categories: jawless fish, cartilaginous fish, and bony fish. It explains the characteristics of each group, such as the lack of paired fins in jawless fish, the cartilage-based skeletons of cartilaginous fish, and the presence of paired gills and scales in bony fish. The video provides examples of each type, including hagfish and lampreys for jawless fish, sharks and rays for cartilaginous fish, and various species found in both freshwater and saltwater for bony fish. The video concludes with a call to action to subscribe and share.
