Coral reefs represent a level of biodiversity that can rival tropical rain forests. Coral reef communities are characterized by an amazing diversity of marine creatures including: sponges, anemones, hard corals, soft corals, hydroids, worms, shrimps, lobsters, crabs, snails, scallops, oysters, octopi, squids, barnacles, sea stars, brittle stars, sea cucumbers, sea urchins, tunicates and many more. On this coral head, the brown bowl sponge first caught my attention. Their colours are so rich and they are often home to small shrimp and crabs. If you look closely you can see a small crab in between the two brown bowl sponges. How many species can you count on this coral head? This image was taken in Little Cayman in 2022.
