There’s nothing scary about pigs. That is, of course, until you equip them with the diet of an omnivore and blow them up to 4-feet or about 1.35-meters tall! The Entelodon is a nightmare pig, though it is actually believed to be more closely related to hippos and whales than to swine. During the Paleogene Period, the Entelodon inhabited much of Europe and Asia, its sheer numbers indicating that it didn’t have a large range of predators. In fact, it’s believed that the Entelodon could easily adapt to changing food sources, making it easy for them to migrate, and was also known for driving off predators from their kill to snag a meal of its own.
