Clownfish (Amphiprion ocellaris)
The Clownfish, immortalised by the cartoon Nemo, from the movie "Finding Nemo", has a mucus membrane that protects him from the poison spikes of the anemones. So, this species of fish uses the anemones for shelter and protection, hiding between their tentacles. Although the clownfish start their life as males, as they grow older, some of them change sex and turn into females that end up dominating the group.
