On November 20, 1820, the Nantucket whaling ship Essex was rammed and sunk by huge sperm whale. Another sperm whale attack occurred the same year Moby-Dick was published. After Melville's death, Moby-Dick was reprinted and, this time around, critics started to take it more seriously. Scientists named a newly discovered sperm whale fossil Livyatan melvillei in 2010. Though roughly the same length as a modern sperm whale, L. melvillei had way bigger teeth.
