In some species the part immediately below the oral disc is constricted and is known as the capitulum. The column or trunk is generally more or less cylindrical and may be plain and smooth or may bear specialised structures these include solid papillae (fleshy protuberances), adhesive papillae, cinclides (slits), and small protruding vesicles. Some species burrow in soft sediment and lack a basal disc, having instead a bulbous lower end, the physa, which anchors them in place. Some are very large Urticina columbiana and Stichodactyla mertensii can both exceed 1 metre (3.3 ft) in diameter and Metridium farcimen a metre in length.

Most are from 1 to 5 cm (0.4 to 2.0 in) in diameter and 1.5 to 10 cm (0.6 to 3.9 in) in length, but they are inflatable and vary greatly in dimensions.

Sea anemones are sometimes kept in reef aquariums the global trade in marine ornamentals for this purpose is expanding and threatens sea anemone populations in some localities, as the trade depends on collection from the wild.ġ.

PharynxĪ typical sea anemone is a sessile polyp attached at the base to the surface beneath it by an adhesive foot, called a basal or pedal disc, with a column-shaped body topped by an oral disc. Sea anemones also breed asexually, by breaking in half or into smaller pieces which regenerate into polyps. The resulting fertilized eggs develop into planula larvae which, after being planktonic for a while, settle on the seabed and develop directly into juvenile polyps. Sea anemones breed by liberating sperm and eggs through the mouth into the sea. Some species of sea anemone live in association with clownfish, hermit crabs, small fish, or other animals to their mutual benefit. In many species, additional nourishment comes from a symbiotic relationship with single-celled dinoflagellates, with zooxanthellae, or with green algae, zoochlorellae, that live within the cells. They are armed with cnidocytes (stinging cells). The tentacles can be retracted inside the body cavity or expanded to catch passing prey. The polyp has a columnar trunk topped by an oral disc with a ring of tentacles and a central mouth. Unlike jellyfish, sea anemones do not have a medusa stage in their life cycle.Ī typical sea anemone is a single polyp attached to a hard surface by its base, but some species live in soft sediment, and a few float near the surface of the water. As cnidarians, sea anemones are related to corals, jellyfish, tube-dwelling anemones, and Hydra. Sea anemones are classified in the phylum Cnidaria, class Anthozoa, subclass Hexacorallia. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. Nemona will Terastallize her starter at the first opportunity.Sea anemones are a group of predatory marine invertebrates of the order Actiniaria. The player's Pokémon will not gain any experience during this battle. First battleĭuring this battle, both the player's and Nemona's Pokémon are prevented from scoring critical hits. She is also implied to have more Pokémon that are unseen by the player, as she became a Champion prior to her first battle with the player and repeatedly mentions needing to select a perfect team for her battles, and the official website for Pokémon Scarlet and Violet claims that Nemona uses Lechonk and Smoliv, even though she is never seen using either of these Pokémon. As shown in the game's opening cutscene, she also owns a Combat Breed Paldean Tauros, but she is never seen using it elsewhere. Nemona uses the starter with a type disadvantage to the one the player chooses. Nemona also participates in the Academy Ace Tournament, although she has to manage the admin work when it is held for the first time, she can be battled as a random opponent in subsequent Academy Ace Tournaments. She, along with the player, is enrolled in the general studies track of the academy, with her homeroom teacher being Jacq. However, she's not as good at throwing Poké Balls. She has an energetic personality, and loves Pokémon battles, which she excels at. Nemona is a Champion-ranked Pokémon Trainer and serves as a reliable guide for the player.
