The ‘platypus’ of crabs

With its adorable big eyes, this predator seemed more Disney than deadly.

A crab roughly the size of a quarter was found in the waters of what is now Colombia 95 millions years ago. It was known for stalking its unsuspecting victims from the dark before gracefully chasing down its prey.

Today, most adult crabs are largely known as bottom-dwellers who have to scavenge and scurry across the sea floor because of their tiny, almost useless eyes. But this long-extinct crab, dubbed Callichimaera perplexa, had unique physical features that made it an agile swimmer that likely zoomed through the water to catch whatever was in its sight.
