Transcription: Fish are vertebrates, animals with a backbone, that are completely adapted for life in water. They breathe underwater and have a streamlined body for swimming. They have fins to propel, balance, and steer themselves. Fish are found in both freshwater and marine habitats. Sharks and rays belong to an ancient group of fish that existed 200 million years before dinosaurs. They are called cartilaginous fish because they have skeleton made of cartilage, a kind of gristle. Their big oily liver helps them float and they have a skin with tooth-like scales.
