Metabolic heat loss in southern elephant seals ( Mirounga leonina ) differs with stage of moult and between habitats
The moult in southern elephant seals ( Mirounga leonina ) represents an especially energetically demanding period during which seals must maintain high skin temperature to facilitate complete replacement of body fur and upper dermis. In this study, heat flux from the body surface was measured on 18...

The moult in southern elephant seals ( Mirounga leonina ) represents an especially energetically demanding period during which seals must maintain high skin temperature to facilitate complete replacement of body fur and upper dermis.
