The Changeable Anemone, scientifically known as Anemonia mutabilis, is a captivating marine invertebrate belonging to the class Hexacorallia, the order Actiniaria, and the family Actiniidae. This species is renowned for its striking appearance and intriguing behavior.
Description & Characteristics
Anemonia mutabilis is characterized by its vibrant and variable coloration, which can range from deep red, orange, and brown to green, yellow, and even white. The anemone’s column, the central body, is typically cylindrical, with a smooth, fleshy texture. It is topped by a disc-shaped oral disc, which houses the mouth and tentacles. The tentacles are numerous and can retract into the oral disc when threatened. The Changeable Anemone can reach a maximum size of about 10 cm in diameter, although most individuals are typically smaller.
Habitat and Occurrence
The Changeable Anemone is a common inhabitant of the subtidal, sublittoral, infralittoral, and deep zones of the oceans, ranging from the lower limit of the intertidal zone to the shelf edge at approximately 200 meters water depth. This species is often found in neritic environments, meaning they inhabit waters over the continental shelf. These anemones prefer hard substrates, such as rocks, shells, and piers, where they can attach themselves securely.
Taxonomy
The Changeable Anemone, Anemonia mutabilis, is a member of the class Hexacorallia, a group of sea anemones known for having six or multiples of six tentacles. The order Actiniaria encompasses all sea anemones, characterized by their solitary, cylindrical bodies and their ability to retract their tentacles. Finally, the family Actiniidae, which includes the Changeable Anemone, comprises some of the most common and widely distributed sea anemones.
Feeding
Anemonia mutabilis is a carnivore, primarily feeding on small invertebrates, such as crustaceans, mollusks, and fish. The anemone’s tentacles are equipped with stinging nematocysts, which paralyze and capture prey. Once immobilized, the prey is transported to the mouth and ingested.
