That's Correct!
It's Wrong!
The correct answer is "Shark". Sharks possess skeletons made of cartilage, which is a flexible and lightweight material. Cartilage is also found in human noses and ears, while bones are rigid structures. This cartilaginous skeleton gives sharks advantages in buoyancy and flexibility in their aquatic environments. In contrast, whales, which are classified as mammals, have bony skeletons.
