What are facts about sea creatures?

A Clown Fish can Live in the Sea Anemone and not be stung because it is covered with a thick layer of mucas. Basically, it is immune to the sting. It's a win-win situation too because the Sea Anemone munches on the Leftover Food Scraps by the Clown Fish. Other than that, I have NO idea what some interesting facts about Sea Anemones. That's why I was on this Website in the First Place!
