Crab walks around with Jellyfish on its back to protect it from predators

These #jellyfish Cassiopea (upside-down jellyfish) partake in a symbiotic relationship with photosynthetic dinoflagellates and therefore, must lay upside-down in areas with sufficient light penetration to fuel their energy source. Where found, there may be numerous individuals with varying shades of white, blue, green and brown.

Sometimes this jellyfish is picked up by the #crab Dorippe frascone and carried on its back. The crab uses the jellyfish to defend itself against possible predators.
