How diving marine mammals manage decompression.

ScienceDaily (Dec. 21, 2011) — Any diver returning from ocean depths knows about the hazard of decompression sickness (DCS) or “the bends.” As the diver ascends and the ocean pressure decreases, gases that were absorbed by the body during the dive, come out of solution and, if the ascent is too rapid, can cause bubbles to form in the body. DCS causes many symptoms, and its effects may vary from joint pain and rashes to paralysis and death.

But how do marine mammals, whose very survival depends on regular diving, manage to avoid DCS? Do they, indeed, avoid it?
