Golfingiidae
The Golfingiidae are a family of marine worms, belonging to the phylum Sipuncula, commonly known as peanut worms. These soft-bodied invertebrates are distinguished by their unique body structure and burrowing lifestyle.
Characteristics
Golfingiidae are characterized by their cylindrical, unsegmented bodies, which taper at both ends. They have a retractable introvert, which is a fleshy proboscis that can be extended for feeding and retracted for protection. The introvert is covered in numerous tentacles, which are used to capture food particles. Golfingiidae also possess a distinctive horseshoe-shaped ring of muscles around the anus.
Environments
These worms are found in a variety of marine environments, including sandy beaches, mudflats, and rocky shores. They are typically found burrowed in the sediment, where they feed on detritus and microorganisms. Some species may also be found in association with sponges or other marine organisms.
Common Names
Golfingiidae are often referred to as peanut worms due to their resemblance to peanuts when contracted. They may also be called "sipunculids" or "peanut worm sipunculids" to distinguish them from other members of the Sipuncula phylum.
