From the Daily What:

“E.T. the walrus was a starving orphan pup when he was discovered by Prudhoe Bay oil workers in 1982. Tacoma’s Point Defiance Zoo & Aquarium decided to adopt him, naming him E.T. because of a certain resemblance to the early ’80s movie star.

E.T., who now weighs about 3,500 pounds, just celebrated his 30th birthday.”
