#3 – Cyclops Shark
No, this is not Mike from Monsters Inc. In 2011, a fisherman by the name of Enrique Lucero León captured a dusky shark while in the Gulf of California. It was pregnant, and when he opened the body up, he found this frightening looking creature inside. While it was initially thought to be a hoax, León brought the specimen to National Geographic scientists and it was deemed to be the real deal.
