Probably other animals I guess. Now that not many hookers/escorts and other very sexually active people have pubes they may be an endangered species. Maybe we should start a Save The Crabs organization. We could get someone like Madonna to be our spokesperson.
Science claims that you cannot get crabs from other animals. Thus, they are a human condition. With no human pubic forest to hide in, they may very well become endangered. But, I doubt it. My guess is there are plenty of folks who still sport pubes....likely, most people don't shave their nether regions.

phthirus pubis (crabs) are basically just lice.
