are sperm whales buoyant
The spermaceti organs may also help adjust the whale's buoyancy. It is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature.The wax therefore solidifies and reduces in volume.t is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature.

Sperm whales are the largest toothed whales on the planet, and perhaps the most abundant of the great whales, but we rarely get to study them because they spend so much time underwater. Sperm whales are deep divers, holding their breath and diving thousands of feet down to feed on deep sea squid and fish.
