Ocellaris anemonefish (Amphiprion ocellaris) hidden in a magnificent sea anemone (Heteractic magnifica) on a coral reef. Anemonefish, also called clownfish, 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. Photographed in the Andaman Sea, Thailand.
