Copidaster cavernicola is a species of starfish belonging to the family Ophidiasteridae. It is a relatively small starfish, known for its distinctive morphology and interesting habitat preferences.
Description & Characteristics
Copidaster cavernicola is characterized by its compact, rounded body, typically reaching a maximum size of 5 cm in diameter. The starfish’s upper surface, or aboral side, is covered in numerous, small, granular ossicles, giving it a rough texture. The color of Copidaster cavernicola can vary depending on the individual and its environment, ranging from a pale cream to a reddish-brown hue.
Habitat and Occurrence
Copidaster cavernicola is primarily found in the Indo-Pacific region, inhabiting a wide range of marine ecosystems. This species is often encountered in shallow, sheltered areas, particularly in rocky crevices and coral reefs. Copidaster cavernicola is also known to inhabit caves and overhangs, where it finds shelter and protection from predators. Its preference for these habitats has earned it the common name “Cave Starfish”.
Taxonomy
Copidaster cavernicola belongs to the Class: Asteroidea, which encompasses all starfish species. Within this class, it falls under the Order: Valvatida, an order characterized by its star-shaped morphology and the presence of pedicellariae (small pincer-like appendages) on the surface of the body. Copidaster cavernicola is further classified within the Family: Ophidiasteridae, a family known for its diverse array of species, including many that exhibit a colorful appearance.
Feeding
Copidaster cavernicola is primarily a carnivorous starfish, feeding on a variety of small invertebrates, such as crustaceans, mollusks, and worms. It captures its prey using its tube feet, which are covered in adhesive mucus. Copidaster cavernicola is an important member of the marine food web, playing a role in regulating populations of smaller invertebrates and contributing to the overall health of the ecosystem.
