Awesome footage, filmed on June 3, of decorator crabs off the coast of Indonesia using other animals, such as jellyfish, as shells. <br /><br />The video shows the strange but beautiful creatures grab other animals and use the stings and venom to defend themselves. <br /><br />The filmer later wrote online: "Stinging or poisonous critters like sea urchins or upside-down jellyfish are particularly popular. <br /><br />"It often comes to the surprise of divers, when the usually slow animals suddenly start running, and only the second view reveals they're stuck on the back of a crab."
