Definition
"Order Actiniaria" is a group of marine invertebrates consisting exclusively of sea anemones. These animals are solitary polyps, meaning they exist as individual organisms, unlike colonial corals. They are characterized by a cylindrical body topped with a ring of tentacles surrounding a central mouth. Think of them as underwater flowers that pack a sting. They use these tentacles to capture prey. They're generally sessile, but can slowly move. 🌷
