Adaptation
The site below describes the many adaptations of the Walrus. I will choose a few of the adaptations that I find most interesting.
- the walrus uses it’s tusks to battle it’s predators, to protect their babies and use them to glide across the bottom to find food
- it plows through the sediment on the ocean floor with their noses.
- object is identified with the whiskers.
- if clam, the foot of the clam is taken between the lips, and the soft parts are sucked from the shell and swallowed
- the walrus uses it’s tusks to lift itself up out of the water and onto the ice
