Figure 9.4 A group of resting Weddell seals on the summer sea ice of McMurdo Sound, Antarctica.
These animals can face winter air temperatures in this region as low as −50°C, before factoring in
the effects of convection, or wind chill. (Photo by D. Uhlmann, NMFS 1034–1854.)

water of McMurdo Sound, Antarctica. (Credit to H. Kaiser, NMFS 15748.)
Figure 9.3 An infrared image reveals the hot (red) and cold (blue) surface temperatures on the face
of a Weddell seal pup. Most of the pup surface remains cool, with the exception of the un-insulated
eyes, lightly insulated head, and highly vascularized muzzle. (Photo by J. Mellish, NMFS 15748.)
