Scaling of insulation in seals and whales
We describe scaling of morphological variables that influence total insulation in eight species of marine mammals ranging in average size from 35 to 30000 kg. We also calculate total heat loss and the partitioning of heat loss through the body surface and appendages. For the eight species investigat...

We describe scaling of morphological variables that influence total insulation in eight species of marine mammals ranging in average size from 35 to 30000 kg. We also calculate total heat loss and the partitioning of heat loss through the body surface and appendages.
