Through Worm
The Canalipalpata have no teeth or jaws. Most are filter feeders. They have grooved palpi, which are covered in cilia. These cilia are used to transport food particles to the mouth. However, the cilia and grooves have been lost in the Siboglinidae family.
Fossil record
The earliest known member of the Canalipalpata is Terebellites franklini, which was found in the Clouds Rapids Formation of Newfoundland, and dates from the mid Cambrian (St David's series).
