The Trumpet Anemone, scientifically known as Aiptasia mutabilis, is a small, hardy anemone commonly found in tropical and subtropical waters. It is a popular choice for beginner aquarists due to its relatively easy care and adaptability. Its trumpet-shaped body with a distinctive oral disc and tentacles make it an intriguing addition to any marine tank.
Description & Characteristics
The Aiptasia mutabilis is a relatively small anemone with a maximum size of around 2 inches (5 centimeters) in diameter. It features a cylindrical body that tapers towards the base, resembling a trumpet. The oral disc, which is located at the top of the body, is surrounded by a ring of tentacles. These tentacles can vary in number but typically range from 20 to 40. Their color can vary, ranging from green and brown to orange and red, with some individuals displaying multiple colors. The presence of symbiotic algae called zooxanthellae within the tissues of the Aiptasia mutabilis contributes to its vibrant coloration.
Habitat and Occurrence
The Trumpet Anemone, Aiptasia mutabilis, is often found in the Supratidal (Supralitoral) zone, the spray water area (splash water area) above the tidal influence where the influence of the sea clearly outweighs that of the land. This zone is characterized by its exposure to both seawater and air, and the Aiptasia mutabilis has adapted to survive in this harsh environment. It prefers rocky shores, rock crevices, and rock coasts, providing a stable substrate and protection from strong currents.
Taxonomy
The species Aiptasia mutabilis belongs to the Class: Hexacorallia, Order: Actiniaria, and Family: Aiptasiidae. Hexacorallia is a class of cnidarians, a group of aquatic invertebrates, that possess radial symmetry and stinging cells called nematocysts. Actiniaria encompasses the order of anemones, known for their solitary lifestyle and lack of a hard skeleton. The family Aiptasiidae includes several species of anemones, characterized by their small size and adaptability.
Feeding
The Trumpet Anemone is a carnivore and feeds primarily on a variety of small invertebrates, including brine shrimps, copepods, Daphnia salina, krill, mysis, and smelts. Its tentacles are lined with stinging cells that paralyze prey, allowing the anemone to bring its food to its mouth. However, the Aiptasia mutabilis also derives nutrition from zooxanthellae, symbiotic algae that live within its tissues. These algae photosynthesize, providing the anemone with energy through the process.
