Ambergris

Do you know what ambergris is? I've heard of it before, and all I knew was that it was a vaguely nautical substance that's mentioned in sea-fairin' tales and the like. I found out recently that it's really expensive, so expensive, in fact, that if you find a chunk of it on a beach, you can use the proceeds to buy a house or two.

Ambergris has been used as an ingredient in perfume for ages due to its unique odor and properties. It comes only from sperm whales. Because the whales eat lots of giant squid, a substance forms in their digestive tracts that protects them from the squid's sharp beaks. After this substance collects inside a whale for some time, the whale will belch out a big ball of it into the water.

However, at this point, the ball of stuff is just smelly and disgusting and repellent. In order for it to achieve the texture, fragrance and chemical properties that make it more valuable, it has to float around in the ocean.

For TEN YEARS.

Oh wait, I forgot to mention that it's believed only one percent of sperm whales actually produce this substance.

So keep your eyes peeled.

Oh, one more thing, it's illegal to posses it in the US because of the Endangered Species Act of 1978.

Nighty night.
