Unlike us humans, Gray whales have a flexible rib cage. When diving to deep depths, it easily bends under pressure without breaking. The tail is made up of two large flukes with a notch in between them. The flukes are controlled by a massive muscle system in the peduncle. These muscles account for a third of the whale’s total body weight.

The rib cage and lungs of the whale are actually adapted to collapse under pressure, squeezing all the air the lungs contain into a small space. When the sperm whale dives, the concentration of oxygen containing molecules in the blood and muscles—hemoglobin and myoglobin—are increased to hold more oxygen in the tissues.
