Red Sea clownfish (Amphiprion bicinctus) and diver. This is a clownfish pair with corals and their host anemone (lower left). Clownfish, also called anemonefish, live in association with anemones. Both partners benefit in a mutualistic association. Slime on the fish's skin prevents the anemone's stinging cells from damaging it. The fish sleeps, evades danger, eats, and lays its eggs between the poisonous tentacles. The anemonefish cleans the anemone and also ensures a supply of food detritus for the anemone to feed on. This fish can reach a length of 14 centimetres. It is found in the western Indian Ocean and the Red Sea. Photographed on Egypt's Red Sea coast.
