| Polar bear cubs learn to freeze and remain still while
their mother hunts. If they move, the mother disciples them,
with a whack to the head. |
Female polar bears would rather build their dens in
"old snow" from previous years rather than the freshly
fallen snow. |
Some female polar bears deviate from the one room
den. They build dens with multiple rooms and even a ventilation
system in the roof. |
