Sharks - What are sharks?","","A children’s nonfiction book introducing sharks, their body structures, diversity, and habitats. It explains how shark skeletons are made of cartilage instead of bone, highlights that there are more than 450 types of sharks with varied shapes and sizes, and describes specific examples such as spinner sharks, angel sharks, and pygmy sharks. It also places sharks in deep time, noting their presence in seas for hundreds of millions of years before dinosaurs and discussing early shark
