Common clownfish in a sea anemone, Raja Ampat Islands, Indonesia

Sea anemones may look like underwater flowers, but they"re actually animals—close relatives of jellyfish and corals. Anchored to rocks or reefs, they use a sticky base and a crown of waving tentacles armed with tiny stingers to capture passing prey. Those stings can paralyze small fish, yet one famous neighbor is immune.
