The Slender Ragwormpelagic, Clam Worm, scientifically known as Nereis pelagica, is a marine worm belonging to the family Nereididae. It is a common and widely distributed species, found in various marine environments.
Description & Characteristics
Nereis pelagica is characterized by its slender, elongated body. It can reach a maximum size of up to several inches in length. The worm possesses numerous bristle-like structures called setae along its body, which aid in locomotion. The body is segmented, with each segment bearing a pair of parapodia, fleshy appendages used for swimming and burrowing.
Habitat and Occurrence
Nereis pelagica is typically found in shallow coastal waters, including intertidal zones, estuaries, and bays. They are often associated with sandy or muddy substrates. The Slender Ragwormpelagic, Clam Worm exhibits a preference for environments with ample organic matter, making it a common inhabitant of seagrass beds, kelp forests, and other areas rich in detritus. This species is distributed across various marine zones, including the neritic zone, which refers to the shallow waters extending from the coastline to the edge of the continental shelf.
Taxonomy
The species Nereis pelagica belongs to the Class: Polychaeta, Order: Phyllodocida, and Family: Nereididae. Polychaeta, a class within the phylum Annelida, encompasses a diverse array of marine worms. The Order Phyllodocida comprises worms possessing well-developed parapodia, characterized by their flattened shape. The Nereididae family, within the Phyllodocida order, is known for its numerous members, including various species of marine worms like Nereis pelagica.
Feeding
Nereis pelagica is an omnivorous species, meaning it feeds on a wide range of food sources. Its diet includes bacteria (bacterioplankton), detritus, and smaller invertebrates. This diverse diet makes it an important part of the marine ecosystem, contributing to nutrient cycling and food web dynamics.
