20.000 legues under the sea

Twenty Thousand Leagues Under the Seas (French: Vingt mille lieues sous les mers) is a classic science fiction adventure novel by French writer Jules Verne.

Its depiction of Captain Nemo's underwater ship, the Nautilus, is regarded as ahead of its time, since it accurately describes many features of today's submarines, which in the 1860s were comparatively primitive vessels.

During the year 1866, ships of various nationalities sight a mysterious sea monster, which, it is later suggested, might be a gigantic narwhal. The U.S. government assembles an expedition in New York City to find and destroy the monster. Professor Pierre Aronnax, a French marine biologist and the story's narrator, is in town at the time and receives a last-minute invitation to join the expedition; he accepts. Canadian whaler and master harpooner Ned Land and Aronnax's faithful manservant Conseil are also among the participants.
