Mocha Dick the sperm whale
Mocha Dick was another famous white whale. This ferocious fighter was so well-known to 19th-century whalers that he inspired Herman Melville's classic, "Moby Dick."
Mocha was an albino sperm whale that reportedly survived more than 100 encounters with whalers before he was eventually killed. He was docile when unprovoked but would turn into an aggressive fighter when attacked, using his body to smash the boats of those who sought his blubber.
He was killed in 1838 after coming to the rescue of a cow that had just lost a calf to whalers.
