The academy plans to have cake, party hats and songs for Claude's birthday on Wednesday. Academy officials say the animal, which has a mutation that makes it white, is a big draw and can also be used to teach people about the environment and evolution.
He weighs 181 pounds and measures 8 feet 5 inches long. He could live to be 80 years old.
Claude and another alligator shared a tank for several months before that alligator was sent back to Florida when it bit Claude on his right front foot.
