Pacu Fish ! Nature#4

This fish is my favorite animal on this list in regards to how bizarre is its unique body part. Pacu fish is well-known around the world for having teeth that strongly resemble human teeth. These fish are actually a close relative of piranhas, which isn’t that surprising really. They also live in the waters of South America like piranhas do. At least getting bitten by a pacu fish isn’t so painful as getting bitten by a piranha.
