👉 Echinocereae is a family of marine invertebrates, commonly known as sea anemones. These animals are characterized by their large, flattened bodies and numerous arms or tentacles that can extend from the base of the body to form a series of spirals or tubes called "cilia." Echinocereae are often found in the open ocean, but they can also be found in freshwater environments such as seashells, mud, and even coral reefs.
