Thermoregulation and energetics of fin and sei whales based on postmortem, stratified temperature measurements
It has been postulated that large whales have uniform body temperatures and may experience heat stress in warm waters or when active in colder water. Postmortem (approximately 15 min), stratified body-core temperature measurements of fin and sei whales (Balaenoptera physalus, B. borealis), taken fro...
