A beloved albino alligator named Claude at the California Academy of Sciences in San Francisco has died at age 30. The museum announced his death on Tuesday. Claude was an unofficial mascot and appeared in children’s books and ads. He captivated visitors with his “quiet charisma” during his 17 years at the museum. Claude was born in 1995 in Louisiana. He was born with albinism, which made him appear white and his eyes pinkish-red. He recently underwent treatment for a suspected infection. The museum plans a public memorial, and people can share memories via email or post.
