Antedon loveni, commonly known as the feather star, is a species of crinoid, a group of marine animals characterized by their distinctive feather-like arms. These fascinating creatures, also known as sea lilies, are part of the larger group of echinoderms, which includes starfish, sea urchins, and brittle stars. They play a vital role in the marine ecosystem, contributing to the balance of the food web and providing shelter and habitat for other organisms.
Description and Characteristics
Antedon loveni is a relatively small crinoid, with a maximum arm span of around 15 centimeters. Its body is composed of a central cup-shaped structure called the calyx, from which five arms extend outwards. Each arm is further subdivided into numerous pinnules, giving the animal its feather-like appearance. The color of Antedon loveni can vary considerably, ranging from white and pale gray to brown and reddish tones. This variation in color is influenced by environmental factors and the species’ diet.
Habitat and Occurrence
Antedon loveni is primarily found in the northeastern Atlantic Ocean, with a distribution extending from the British Isles and the Norwegian coast south to the Mediterranean Sea. This species is known to inhabit a variety of marine environments, from shallow coastal waters to deeper depths. It is often found attached to rocky substrates, seaweeds, and various types of marine debris. Antedon loveni is typically found in the neritic zone, a region extending from the shoreline to the edge of the continental shelf, where it thrives in the presence of currents and sufficient food sources.
Taxonomy
Antedon loveni belongs to the class Crinoidea, a group of echinoderms characterized by their feather-like arms. Within this class, it is further classified into the order Comatulida, which includes the most common and diverse types of crinoids. Antedon loveni is a member of the family Antedonidae, a group of crinoids known for their relatively small size and widespread distribution in various marine habitats.
Feeding
Antedon loveni is a suspension feeder, meaning it obtains its food by filtering small organisms and particles from the surrounding water. Antedon loveni utilizes its arms and pinnules to create a current that carries food particles towards its mouth, which is located in the center of its calyx. This process is essential for the survival of Antedon loveni and contributes to the overall health of the marine ecosystem by regulating the abundance of small organisms.
