Question

Sharks are the only species to have cartilage.


true


false

Answer 1

False. Sharks are not the only species to have cartilage; many other animals, including rays and skates, also have cartilage instead of bones. In fact, all members of the class Chondrichthyes, which includes sharks, rays, and skates, have skeletons made of cartilage. Additionally, some other species, such as certain types of fish and amphibians, also have cartilaginous structures at various stages of their development.
