What was the name of Captain Nemo's submarine in "20,000 Leagues Under the Sea"?

The story behind the answer

The correct answer is The Nautilus—Captain Nemo’s pioneering, electrically powered submarine in Jules Verne’s 1870 novel Twenty Thousand Leagues Under the Sea. Verne named it after the spiral-shelled sea creature and Robert Fulton’s early real-world submarine, grounding his fiction in plausible science.

To remember it, think “Nautilus” ≈ “nautical,” the perfect name for a vessel that roams the oceans. Aboard the Nautilus, Nemo and crew battle a giant squid and tour the world beneath the waves, while Verne famously anticipates technologies like electric lighting and scuba gear. The Nautilus returns in The Mysterious Island, sealing its status as literature’s quintessential submarine.
