Sharks do not have any bones in them. They have skeletons made of cartilage. Some sharks are always moving. They never stay in the same place for long. If sharks stop moving they suffocate and dye because they take up all of the oxygen. They have great hearing and can hear a fish up to 500 meters. Some sharks lay eggs rather than live birth.
