Clownfish and AnemonesColorful clownfish swim among an array of sea anemones. Anemones appear in an enchanting variety of shapes and colors, but these simple invertebrates are essentially tubelike animals. One end of an anemone’s body is attached to or dug into the seafloor, while the other hosts a mouth surrounded by tentacles.
