The Spaghetti Worm – Eupolymnia crassicornis is a marine worm belonging to the family Terebellidae. It is a common inhabitant of various marine ecosystems, particularly those in the intertidal zone and shallow subtidal areas.
Description & Characteristics
The Spaghetti Worm – Eupolymnia crassicornis is characterized by its long, slender body and numerous, hair-like appendages called “setae.” The body can reach up to 10 cm in length and is typically cream-colored, with a distinctive red or brown stripe running along its dorsal surface. The numerous setae, which resemble spaghetti strands, give the worm its common name. These setae are used for locomotion and anchoring the worm to its burrow.
Habitat and Occurrence
The Spaghetti Worm – Eupolymnia crassicornis is found in a variety of marine environments, including intertidal zones, shallow subtidal areas, and deeper waters. It is a common species in the northeastern Atlantic Ocean, the North Sea, and the Mediterranean Sea. This species prefers soft sediment substrates, often found in areas with moderate wave action and currents. The Spaghetti Worm – Eupolymnia crassicornis can be found at depths ranging from the intertidal zone to approximately 100 meters.
Taxonomy
The Spaghetti Worm – Eupolymnia crassicornis belongs to the Class Polychaeta, Order Terebellida, and Family Terebellidae. Polychaetes are a diverse group of segmented worms, characterized by their numerous bristle-like appendages. The Order Terebellida includes a variety of burrowing polychaetes, known for their distinctive tube-dwelling habits. The family Terebellidae encompasses a broad range of species, including the Spaghetti Worm – Eupolymnia crassicornis, which is distinguished by its long, slender body and numerous setae.
Feeding
The Spaghetti Worm – Eupolymnia crassicornis is a deposit feeder, meaning it obtains its nourishment from the sediment it inhabits. Its diet consists primarily of algae, foraminifers (single-celled organisms with shells), and mucus. The Spaghetti Worm – Eupolymnia crassicornis uses its tentacles to collect food particles from the surrounding sediment, transporting them to its mouth for consumption.
