>>112745217Butanethiol, also known as butyl mercaptan, is a volatile, clear to yellowish liquid with a fetid odor, commonly described as "skunk" odor. In fact, butanethiol is structurally similar to several major constituents of a skunk's defensive spray but is not actually present in the spray.
You'd think predators would have evolved which didn't mind. The problem is, once sprayed, you can't stalk/hunt anything. It's like waving a flag. So you starve to death.
