Clownfish

Nemo's real-life doppelganger with a taste for anemone rent-free living/Marine Life

The clownfish (Amphiprioninae) is one of the few fish that can live among the stinging tentacles of sea anemones without being harmed, thanks to a protective mucus coating. They are sequential hermaphrodites — all are born male, and the dominant fish in a group becomes female. The largest individual in a colony is always the female, proving that size really does matter in fish politics.
