Macrodactyla fautinae is a species of sea anemone belonging to the family Actiniidae. It is a relatively common and well-studied species, known for its distinctive appearance and behavior.
Description & Characteristics
Macrodactyla fautinae is characterized by its cylindrical body, which can reach a maximum size of around 50 millimeters in height. The column, or body, of the sea anemone is often smooth and can be various colors, including shades of green, brown, and orange. Its most distinctive feature is its long, slender tentacles, which can extend outwards from the oral disc, giving the anemone a distinctive appearance. The tentacles are covered in stinging cells called nematocysts, which the anemone uses to capture prey.
Habitat and Occurrence
Macrodactyla fautinae is typically found in the intertidal zone, the area between high and low tide. It prefers rocky substrates, often found in tide pools or amongst seaweeds. This makes it a prevalent presence in the nearshore environment, especially in areas with strong tidal currents. This species is also known to occur in the subtidal zone, extending down to depths of around 20 meters. This species is found in the marine zones ranging from the infralittoral to the circalittoral zone.
Taxonomy
Macrodactyla fautinae is classified within the Class: Hexacorallia, which encompasses a diverse range of corals and anemones. It belongs to the Order: Actiniaria, which includes all solitary sea anemones. This species is part of the Family: Actiniidae, a large family of sea anemones that are commonly found in a variety of habitats.
Feeding
Macrodactyla fautinae is a carnivorous animal that feeds primarily on small invertebrates such as crustaceans, polychaetes, and other small organisms. Its stinging tentacles paralyze prey, which is then transported to the mouth by the tentacles and ingested. The anemone’s feeding habits are influenced by the availability of prey in its environment, and it is often observed actively hunting for food.
