Its not a Cuban crocodile eating the giant sloth, shoot! The Cuban crocodile used to eat the now extinct giant sloth and other mammals that lived in the olden times. They lived in a swamp in the Pleistocene era. The Cuban Crocodile eats fish, frogs, and toads, since the Giant Sloth is extinct. The Cuban crocodile today can grow to be 10-15 feet long. Did you know it is very relaxed because it is the biggest predator in the swamp . It is a fierce fighter to its preys and enemies. If you mess up it's day, it will mess up your day! Now I must go. A Cuban Crocodile is coming! Bye!
