This worm is commonly seen on sand bars at the low water mark and
on stones on the mid water mark, usually near seagrasses. The thin
tubes of large numbers of the worm form shaggy rugs that people often
overlook and simply step on!
The tubes are thin, 1-2mm in diameter. The thin, brown tubes are often
mistaken for seagrass roots or stems. Densely packed together, the
tubes look like a hairy rug left on the shore. Sometimes, a colony
can cover several metres. The actual animals are thin and long, thus
described as thread-like.
What does it eat? It is a deposit feeder, eating sediments
and digesting the organic, edible bits.
Role in the habitat: The worms
and their tubes might play a role in keeping sediments down and creating
mounds that trap pools of water at low tide for small creatures to
shelter in. Seagrasses and seaweeds often grow among the mat of tubes.
