Crossing Paths With A Narwhal | The Magical Aquatic World with Philippe Cousteau


– A narwhal’s horn is
actually an enlarged tooth and not a horn at all. And today, we’re talking about narwhals, unicorns of the sea. Nice shirt. – Thanks. (light piano music) – My grandfather, Jacques Cousteau, studied and explored the Earth’s ocean. I do too. And our submarine is in arctic waters, searching for the narwhal. (errr, errr, er, er) Oh, he’s a beauty. Now, narwhals can grow
up to 17 feet in length, and their front tooth can
grow up to 10 feet in length. It’s the only straight tusk in the world. But typically, these
are only found on males and are actually full of up
to 10 million nerve endings, helping the narwhal detect
pressure, salt levels and even temperature in the water. Here’s an interesting fact, a narwhal tusk is flexible. It can bend about one
foot in any direction, without breaking. It was originally thought that these tusks were for dueling. But a new theory suggests,
they’re for attracting a mate. Narwhals don’t migrate
like other whale species. They spend their entire
lives in icy, arctic waters hunting squid, fish and crab. If you want to see one live, you’ll have to come up north because narwhals don’t
thrive in captivity. Rather, they die. Some animals, we humans just can’t tame.
