Tusky

Tusky, also known as Tusky the Walrus, is a fictional... well... you know... a walrus. He appears in comic books and related media produced by DC Comics. He is associated with the Aquaman line of comic book titles.

Tusky is a male walrus with a brown pelt. He is a pet companion of Aquaman, as well as his junior sidekick, Aqualad. Tusky has accompanied the undersea duo on many of their adventures, and has often eagerly helped them out against various threats whenever he could. Tusky has the unbelievable ability to not only survive underwater for an indeterminate amount of time (he is a mammal after-all), but can apparently hang out at the depths of the ocean floor without suffering any undue strain from the pressure. Friggin' mutant walrus.
