Terebellidae

Terebellidae, commonly known as spaghetti worms or spaghetti tube worms, are a family of marine polychaete worms. They are found in all oceans, from the intertidal zone to the deep sea, and inhabit a variety of substrates including sand, mud, and coral reefs. These worms are characterized by their numerous, long, slender feeding tentacles, which they extend from their burrows or tubes. These tentacles are ciliated and coated with mucus, used to capture food particles from the surrounding environment. The body of a terebellid is typically segmented and can vary in size from a few millimeters to several centimeters in length. They construct tubes made of secreted mucus and sand or shell fragments, providing shelter and protection. Terebellids are deposit feeders, meaning they consume organic matter that settles on the seabed. Their feeding tentacles play a crucial role in this process, gathering detritus and small organisms. Reproduction in terebellids is generally sexual, with external fertilization being common. Larvae are planktonic before settling to the seafloor. While not typically exploited by humans, terebellids are an important part of marine benthic ecosystems, serving as a food source for various invertebrates and fish. Their presence and abundance can also be indicators of sediment quality.
