It is 10-25 centimetres in length. Its body is elongated and divided into 100-600 small segments. The head has two fans of feathery tentacles arising from fleshy, semi-circular lobes. The body is mostly grey-green while the tentacles are brown, red or purple with darker bands.
The worm lives inside a smooth tube of fine mud or sand particles held together with mucus. The tube stands upright with the lower end attached to stones and the upper end protruding from the sea bed. When covered by water, the worm extends its tentacles out of the tube to feed by filtering out small food particles.[1] At low tide or when disturbed, it withdraws back into the tube.
