Actinothoe modesta is a species of sea anemone, a fascinating and diverse group of marine invertebrates known for their colorful and often striking appearance. This particular species is characterized by its relatively modest size and is a common inhabitant of certain coastal regions.
Description & Characteristics
Actinothoe modesta typically reaches a maximum size of a few centimeters in diameter. It is distinguished by its slender, cylindrical body with a smooth, fleshy texture. Its coloration can vary, often displaying shades of brown or gray with lighter, sometimes translucent areas. The tentacles, which are numerous and arranged in rows around the mouth, are relatively short and possess a slightly tapered shape.
Habitat and Occurrence
Actinothoe modesta is primarily found in intertidal and shallow subtidal zones, often inhabiting rocky areas and tide pools. Its distribution extends along the coasts of the northeastern Atlantic Ocean, including the British Isles and the European mainland. This species is particularly well-adapted to the fluctuations in salinity, temperature, and water flow that are common in these coastal habitats.
Taxonomy
Actinothoe modesta belongs to the Class: Hexacorallia, Order: Actiniaria, and Family: Sagartiidae. This classification reflects its shared characteristics with other sea anemones, including the presence of six-fold radial symmetry and a central mouth surrounded by tentacles.
Feeding
Actinothoe modesta is a carnivorous animal and relies on a diet of small invertebrates, such as crustaceans and polychaete worms. The tentacles of this species are covered in stinging nematocysts, which are used to capture and paralyze prey. Once immobilized, the prey is transported to the mouth and ingested.
