Dolphin Skeleton (Gliding Joint)
Observations The dolphin has a very long backbone and tail that helps it move well under water along with protective ribs.
Explanations The dolphin is built to be sleek. Its body is made of almost entirely backbone (a gliding joint) which makes it very flexible under water. The ribs protect the inner organs of the dolphin and the tail beats from side to side, thrusting the animal forward.
