Do dolphins have backbones?
Largely because of the buoyancy of the water, dolphins do not require strong limbs for support. The backbone is very flexible, due to the reduced interlocking of individual vertebrae and the development of large fibrous discs between them, to allow powerful undulations of the tail for swimming.
Do sharks have backbones?
The simple answer to the question do sharks have vertebrae is yes. Sharks are classed as vertebrates because they have a spinal column just like a human, but there’s nothing in the definition that says it must be made of bone. The primary role of the vertebrae is to protect the spinal cord.
What characteristics are common among animals with backbones?
Vertebrates have certain features in common: (1) a vertebral column made out of bone or cartilage; and (2) a hollow dorsal nervous system.
