Swimming speed and allocation of time during the dive cycle of Antarctic fur seals
descent and ascent phases of dives with a reduction in speed near the bottom of the dive, when the seals ... were assumed to be feeding on krill. Surface interval increased as a curvilinear function of dive ... duration and was influenced by diving swimming speed. This relationship was, on average, close to that ... predicted by a model (Houston & Carbone, Behav. Ecol., 3, 255-265) which suggested that the metabolic ...
