Eleutherobia vinadigitaria is a species of soft coral belonging to the family Alcyoniidae. This species is found in a variety of habitats, primarily in shallow marine environments.
Description & Characteristics
Eleutherobia vinadigitaria is a soft coral with a characteristically vibrant appearance. Its polyps, which are the individual feeding units of the coral, are arranged in clusters. Each polyp possesses eight tentacles that are studded with numerous, minute, stinging cells called nematocysts. These stinging cells are used for capturing prey. The coral’s surface is often covered in a thin layer of mucus, which aids in trapping food particles.
Habitat and Occurrence
Eleutherobia vinadigitaria is a common inhabitant of shallow marine environments. It is typically found in the neritic zone, which extends from the shoreline to the edge of the continental shelf. This species favors habitats with a moderate amount of water movement, such as rocky reefs and sandy bottoms.
Taxonomy
Eleutherobia vinadigitaria belongs to the class Octocorallia, which includes all corals with eight tentacles per polyp. This coral is also classified within the order Malacalcyonacea, which comprises a diverse group of soft corals characterized by their flexible, fleshy bodies. Finally, it is a member of the family Alcyoniidae, a family that encompasses numerous species of soft corals, often referred to as “sea fans” or “sea whips.”
Feeding
Eleutherobia vinadigitaria is a carnivorous organism that primarily feeds on small plankton and other microscopic organisms. The coral’s polyps, with their stinging nematocysts, capture prey by paralyzing it and drawing it into the polyp’s mouth. Like many other soft corals, Eleutherobia vinadigitaria also derives some nutrition from symbiotic algae called zooxanthellae that live within its tissues. These algae photosynthesize and provide the coral with organic compounds, contributing to its overall energy budget.
