pacu
Testicle-eating fish. Big fish related to piranha family, native to Southern America. Naturally it feeds on plant seeds and nuts, but can mistake hanging ballsack for edible fruit.
The pacu is not normally dangerous to people but it has quite a serious bite, there have been incidents in other countries, such as Papua New Guinea where some men have had their testicles bitten off
