Editor's note: This hefty marine mammal stars in two cultural icons, one of which influenced the other: Lewis Caroll’s poem “The Walrus and the Carpenter,” which inspired John Lennon to write the hit Beatles tune “I Am the Walrus.” If you happen to be a walrus, you weigh over a ton, have an air sac on your throat that blows up like a pool toy and helps you float, and are smarter than most people realize. If you’re not a walrus, compensate with some cool Walrus wallpapers!
