Herman Melville's novel Moby-Dick is based on a true story about a sperm whale that attacked and sank the whaleship Essex.[5][6] Melville associated the sperm whale with the Bible's Leviathan.[6][7] The fearsome reputation perpetuated by Melville was based on bull whales' ability to fiercely defend themselves from attacks by early whalers, smashing whaling boats and, occasionally, attacking and destroying whaling ships.[citation needed]
