Imagine using your front teeth to pull yourself out of the pool after a long swim. That is what the walrus does.
Imagine using your upper lip to search around on the floor to find your favorite food, lets say pepperoni, because the lights are off. That is what the walrus does.
Imagine holding your breath for 10 minutes and diving to 300 feet. That is what the walrus does.
Imagine being able to sleep while swimming. That is what the walrus does.
Imagine being in freezing water, 8 inches of ice separating you from the air you need to survive. What do you do? Just slam your head into the ice and use your teeth to make an air hole. That is what the walrus does.
The walrus lives in isolated places (cold Arctic regions), so most of what is known about them has been observed from walruses in captivity. This means there is still much to learn about these graceful swimmers who spend two thirds of their lives in the ocean.
What is evident is they are mysterious and pretty bad ass. How many species of animal have a Beatles song about them?
