Actinia

Actinia is a genus of sea anemones, marine animals related to corals and jellyfish. They are soft-bodied creatures with a cylindrical shape and a central mouth surrounded by tentacles, which they use to catch small fish and plankton. Typically found attached to rocks or other underwater surfaces in shallow waters, actinia vary in color and size. They play a vital role in marine ecosystems by providing habitat and participating in the food web. Despite their delicate appearance, they are resilient and can survive in various environmental conditions.
