Walrus pouting for the camera
This just reminded me of that universal pouting pose that young girls do when being photographed. It also gives a good view of their feeding mechanism for sucking the contents out of clams. They have an airtight (actually watertight) mouth and a muscular tongue (just about visible) that creates negative pressure like a piston for sucking shellfish out of their shells. But I can't work out why the lower jaw seems to have discoloured the tusk where it comes into contact. I thought that might have been the cleanest part of the tusk that is regularly "polished" by the lips, but I'm not a dentist.
