Imagine the look on biologist Gerhard Scholtz's face when he looked down at this crab in New Zealand's Hoteo river, only to find three eyes looking back at him. Was this the result of a freak nuclear accident? An alien invasion? A mean trick? Nope. It's just Blinky.

The Amarinus lacustris crab, Scholtz would later conclude in an academic paper, is actually two crabs—conjoined twins. However, the only evidence of the twin is the extra set of eyes, one of which developed right between the normal pair and another grew on the back of its head like an antenna. Blinky's brain is also deformed, so it's kind of a miracle that he was alive when Scholtz pulled him out of the river back in 2007. It just makes you wonder: What other freaks of nature are hiding in that water?
