This review concentrates on the physiological responses, and their control, in freely diving
birds and mammals that enable them to remain submerged and sometimes quite active for …

The number of scientific papers resulting from biologging instruments deployed on marine
mammals is increasing as improved technologies result in smaller devices and improved …

Famed in story as" the great leviathans," sperm whales are truly creatures of extremes.
Giants among all whales, they also have the largest brains of any creature on Earth. Males …

Sexual segregation in foraging is predicted from the great size disparity of male and female
northern elephant seals, Mirounga angustirostris. Our aim was to test this prediction by …

1. Empirical testing of optimal foraging models for breath-hold divers has been difficult. Here
we report data from sound and movement recording DTags placed on 23 short-finned pilot …

The largest of all seals, elephant seals rank among the most impressive of marine mammals.
They are renowned for their spectacular recovery from near-extinction at the end of the …

The diet of adult and juvenile Weddell seals (Leptonychotes weddellii) in McMurdo Sound,
Antarctica, was determined from both scat and stable isotope analyses, to ascertain if …

Although diving birds and mammals can withstand extended periods under water, field
studies show that most perform mainly short, aerobic dives. Theoretical studies of diving …

Species that maintain aerobic metabolism when the oxygen (O2) supply is limited represent
ideal models to examine the mechanisms underlying tolerance to hypoxia. The repetitive …

Establishing where and when predators forage is essential to understanding trophic
interactions, yet foraging behavior remains poorly understood in large marine carnivores …
