Ladies and Gents, meet the “the Jaws of 1850ies: Moby-Dick”. Herman Melville tells the tale of a ship captain’s quest for revenge on a whale that bit off his leg in his book “Moby-Dick; or, The Whale”. Fast forward to 1975, and we have a shark in Jaws to replace the whale.
When Melville wrote his book, people used to hunt whales for... wait for it... oil. The oil was initially used to make candles, light lamps, and make soap. Eventually, its use evolved to oiling machinery. And then, gladly, we almost learnt to leave the whales in peace.
This whale species is called the sperm whale, and it can grow as large as 20 meters (that’s about 4-5 cars put one after another) and dive to 2km (imagine 6-7 Eiffel Towers on top of each other).
