Golfingia (Golfingia) margaritacea is a species of marine worm belonging to the phylum Sipuncula, commonly known as peanut worms. These burrowing invertebrates are characterized by their unique body shape, resembling a peanut when retracted.
Description & Characteristics
Golfingia (Golfingia) margaritacea is a relatively small species, typically reaching a maximum size of approximately 5 cm in length. Their bodies are typically cylindrical, with a distinct anterior end, known as the introvert, which can be extended and retracted. The introvert is equipped with a mouth surrounded by tentacles, which aid in feeding. The body wall is typically smooth and may exhibit a variety of colors, including white, pink, or brown.
Habitat and Occurrence
Golfingia (Golfingia) margaritacea is a common inhabitant of the intertidal and subtidal zones, frequently found in sandy or muddy sediments. This species prefers environments with moderate levels of salinity and oxygenation. The species has a wide geographic distribution, being found in the northeastern Atlantic Ocean, the Mediterranean Sea, and the North Sea.
Taxonomy
Golfingia (Golfingia) margaritacea belongs to the phylum Sipuncula, commonly known as peanut worms. It is classified within the order Sipuncula and the family Golfingiidae. These worms are characterized by their lack of segmentation and their unique ability to retract their introvert, which is a specialized structure for feeding and locomotion.
Feeding
Golfingia (Golfingia) margaritacea is a deposit feeder, meaning it obtains its food by consuming sediment and filtering out organic matter. They use their tentacles to collect sediment and then bring it to their mouth, where it is processed and digested. The ingested material is then expelled as waste through the anus, located at the posterior end of the body.
