Caribbean coral reef
Baby reef in shallow water on Red Sea / Lahami Bay. The Red Sea is a rich and diverse ecosystem. More than 1200 species of fish have been recorded in the Red Sea, and around 10% of these are found nowhere else. This also includes 42 species of deepwater fish. The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline; these fringing reefs are 5000–7000 years old and are largely formed of stony acropora and porites corals. The reefs form platforms and sometimes lagoons along the coast and occasional other features such as cylinders (such as the Blue Hole (Red Sea) at Dahab). These coastal reefs are also visited by pelagic species of Red Sea fish, including some of the 44 species of shark.

A Skunk Anemonefish Clown fish (Amphiprion ephippium) is in a Magnificent Sea Anemone (Heteractis magnifica). The Anemone has stinging venom coated polyps, which the Anemone fish has the ability to cover its body with and use as protection from predators.  In return, the Anemone fish constantly eats parasites from the Anemone, keeping it clean.  A perfect demonstration of a symbiotic relationship in nature.  The location is Phi Phi islands, Andaman Sea, Krabi Province, Thailand.
