Astropecten vappa is a species of starfish belonging to the family Astropectinidae. This species, commonly known as the “five-rayed starfish,” is a captivating inhabitant of the marine environment, showcasing unique characteristics and an intriguing lifestyle.
Description & Characteristics
Astropecten vappa, like other members of the Astropectinidae family, possesses a characteristic five-pointed star shape. Its arms are typically slender and slightly elongated, giving it a graceful appearance. The dorsal surface, or upper side, of the starfish is covered in small, granular ossicles, providing a rough texture. The ventral surface, or underside, features a series of ambulacral grooves that house the tube feet, used for locomotion and feeding. The maximum size of Astropecten vappa can reach up to 10 centimeters in diameter.
Habitat and Occurrence
Astropecten vappa typically inhabits the sandy bottoms of the intertidal and subtidal zones, primarily in the neritic zone. This marine zone extends from the shoreline to the edge of the continental shelf, making it a prevalent presence in these aquatic ecosystems. Astropecten vappa is known to be found in various regions, including the Mediterranean Sea, the Atlantic Ocean, and the Indian Ocean.
Taxonomy
Astropecten vappa belongs to the Class: Asteroidea, Order: Paxillosida, and Family: Astropectinidae. This classification places it within the broader group of starfish, highlighting its evolutionary relationships and shared characteristics with other members of the class.
Feeding
Astropecten vappa is a carnivorous predator, primarily feeding on a variety of invertebrates. This starfish uses its tube feet to capture prey and bring it to its mouth, located on the underside of its central disk. Its diet consists of small mollusks, crustaceans, and other benthic organisms that it encounters on the seabed. Astropecten vappa plays an important role in the marine ecosystem as a predator, contributing to the balance and regulation of populations within its habitat.
