In the Galapagos Islands, a photographer managed to photograph a marine iguana that "wears" crabs as an accessory. In fact, there is a mutually beneficial relationship between these animals: the crabs climb on the iguanas and eat organic waste from their skin. And the iguanas, in turn, get free cleaning. In the end everyone is satisfied, so they treat each other calmly. You may think you're infinitely cool, but you'll never be cooler than this iguana.
