Ophiolepis paucispina is a species of brittle star belonging to the family Ophiolepididae. It is a relatively common and widespread species found in various marine habitats.
Description & Characteristics
Ophiolepis paucispina is a small to medium-sized brittle star, typically reaching a maximum arm span of around 5 cm. Its body, or disc, is usually a pale grayish-white color, often with a faint reddish tinge. The arms are long and slender, with a distinct tapering towards the tips. They are covered in small, inconspicuous spines, hence the species name “paucispina”, which means “few spines”.
Habitat and Occurrence
Ophiolepis paucispina is a benthic species, meaning it lives on the seafloor. It is primarily found in shallow, subtidal habitats, typically inhabiting areas with coral reefs, rocky outcrops, and seagrass meadows. This species has a wide geographical distribution, occurring in the tropical and subtropical waters of the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the western Pacific Ocean. It is a common inhabitant of the neritic zone, the marine environment extending from the coastline to the edge of the continental shelf.
Taxonomy
Ophiolepis paucispina is classified within the phylum Echinodermata, which also includes starfish, sea urchins, and sea cucumbers. It belongs to the class Ophiuroidea, which encompasses all brittle stars. Within this class, it is placed in the order Amphilepidida, characterized by brittle stars with a well-developed dorsal shield and numerous spines. Finally, Ophiolepis paucispina is a member of the family Ophiolepididae, a diverse group of brittle stars known for their often bright colors and delicate, slender arms.
Feeding
Ophiolepis paucispina is a carnivorous species, feeding primarily on small invertebrates like crustaceans, worms, and algae. They use their long, flexible arms to capture prey and bring it to their mouths, located on the underside of their central disc.
