British photographer Dale Morris captured a marine iguana on the Galápagos island of Fernandina with a bright red crab around its neck that looks just like an elegant bow tie. The photos instantly went viral on the Internet. Other photographs by Morris show how several crabs clung to the reptile at once, creating the effect of an unusual "live costume". In nature this is not an accident at all, but a classic example of reciprocity. Mutually beneficial cooperation between two different species. For the Crabs "Grapsos", the iguana serves as a source of reasonable and nutritious food, they work as a personal spa team. Crabs fearlessly crawl on the body of a giant lizard and completely eat mites, parasites and scales carved from the surface of the skin, and the reptiles, in turn, receive a free hygienic cleaning. This is how they live :).
