“The Pacu fish are actually native to the Amazon, and were introduced to Papua New Guinea only about 15 years ago. Traditionally vegetarian, the fish used their molar-like sharp teeth to crack open nuts (no pun intended) and seeds. When veggie food wasn’t available in their new surroundings, they had to resort to eating meat. I suppose this is when they discovered a particular liking towards the meat of human testicles.” w/ photo + video
