Question

Sharks are the only species to have cartilage.


false


true

Answer 1

False. While sharks are well-known for having a skeleton made of cartilage instead of bone, they are not the only species with cartilage. Many other animals, including rays, skates, and some other fish species, also have cartilaginous skeletons. Additionally, cartilage is present in various forms in many other vertebrates, including humans (for example, in the nose and ears).
