Anemone on Seagrass Blade

Seagrasses don't just provide shelter for free-swimming animals, but also are a habitat for non-moving organisms, such as this sea anemone. Sessile animals attached to blades are called epibionts, while algae, bacteria and diatoms are called epiphytes. Epibionts live on many surfaces—even the shells of sea turtles!
