Sea anemones (/ ə ˈ n ɛ m. ə. n i / ə-NEM-ə-nee) are a group of predatory marine invertebrates constituting the order Actiniaria. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia.
Also, hydrostatic nature is common in marine life such as jellyfish and sea anemones. Earthworms have rings of muscles that are filled with fluid, making their entire body hydrostatic. A sea anemone has a hydrostatic head, with arms radiating out around the mouth. This structure is helpful in feeding and locomotion. [5]

Anenthemonae is a suborder of sea anemones in the order Actiniaria. It comprises those sea anemones with atypical arrangement of mesenteries for actiniarians. [1] Superfamilies and families in the suborder Anenthemonae include: [1] Superfamily Actinernoidea Stephenson, 1922. Actinernidae Stephenson, 1922; Halcuriidae Carlgren, 1918
The sea anemones are attached to the ocean floor or submarine canyons by their flexible stems. The anemones vary in size and can reach up to a foot across. How the Tentacles Capture Prey.
The internal structure of a sea anemone consists of the contracting muscles, the gonads, the acontial filaments, and the ostium. The retracting muscles consist of simple longitudinal fibers that contract to move the anemone vertically. The sphincter muscles allow the tentacles to close over the oral disk. The gonads can be found in the mesentery.
