Hey there, little one! Today we're going to learn about spermaceti!
Spermaceti is a waxy substance that's found in the heads of sperm whales. Sperm whales are really big animals that live in the ocean and they can dive really deep and hold their breath for a long time!
Now, the spermaceti that's inside the sperm whale's head is really special because it's able to change its shape. It can go from being a liquid to a solid and back again! Scientists think that this helps the whale control its diving depth and buoyancy.
In the past, humans used to hunt sperm whales for their spermaceti because it was really valuable. They used it to make things like candles, cosmetics, and even ointments for treating wounds!
But don't worry, little one! These days we don't hunt sperm whales for their spermaceti anymore. We've found other materials to use instead, and we want to make sure that all animals are able to live their lives safely and happily in the wild.
