Now you're probably thinking, 'Dumbo Octopus? This thing's an idiot!' So first of all, the reason they call this octopus 'Dumbo', is because he swims with his ears! Isn't he cute. Disgusting. But the thing I like about this creature is that it swallows its food whole. The 20 cm Dumbo Octopus eats worms, crustaceans, and bivalves of the sea. It lives about 7000 meters under the surface of the ocean. Pretty deep.
