An anemone is a small sea creature that looks like an underwater flower but is actually an animal. Sea anemones attach themselves to rocks or coral on the ocean floor, waving their colorful, finger-like tentacles in the water. Those tentacles contain tiny stinging cells that help the anemone catch small fish and plankton for food. If you've seen the movie Finding Nemo, you've seen anemones: clownfish like Nemo live safely among anemone tentacles because they're immune to the sting.

There's also a land flower called an anemone that got its name because its petals seem to dance in the wind.

Sea anemones are fascinating because they seem to blur the line between plant and animal. They stay in one spot like plants and they look like flowers, but they're definitely animals because they eat other creatures, they can move (very slowly), and they don't make their own food through photosynthesis like plants do. Some species live for decades or even centuries, patiently waiting in the same spot for prey to swim within reach of their stinging tentacles.
