Buoyancy Regulation and the Energetics of Diving in Dolphins Seals, Sea Lions and Sea Otters.
We examined swim speed and ascent descent rates in sea lions and elephant seals in order to make comparisons in their diving strategies and how these may be effected by different strategies of buoyancy regulation. We experimentally examined the relationship between buoyancy and diving behavior in Ju...
