Coral Reef Poster
Under the picture it says:
In clear, shallow tropical seas, corals build vast, stony reefs whihc nurture thriving communities of marine life, dazzling in their beauty and diversity. Here corals, fishes, shrimps, crabs, urchins, sea stars, sponges and countless other animals and plants interact in intricate and dynamic dramas as they compete for food and living space on the reefs. Cooperative relationships between species enable some small fish and shrimp to establish cleaning stations, where larger fish are rid of parasites and the cleaners get a tasty meal. Small anemonefish and cardinal fish find safe haven among an anemone's stinging tentacles or sharp urchin spines. Because of their stripes and spots many brightly colored animals blend in with their background. Other, like lionfish, advertise their dangerous spines to keep predators away.
