Known as ambergris, the excrement of sperm whales, which is rumoured to be a by-product of the whale trying to digest indigestible items, used to be very popular in perfumes. It has a sweet smell once it ages, which is why it is used in perfumes even now. But since it led to the hunting of sperm whales, it is now made synthetically.
