Canalipalpata are an order of the marine polychaete worms. Species in this order are mostly filter feeders owing to a lack of teeth. Within the known 31 families are some quite remarkable species, including the Pompeii worm that can withstand temperature gradients of 60C (140F) and the multicoloured and spiraled Christmas tree worms which are found burrowing in coral around the world's tropical oceans.
Scientific name: Canalipalpata
Canalipalpata, also known as bristle-footed annelids or fan-head worms, is a subclass of polychaete worms, with 31 families in it including the Sabellida (tubeworms, fanworms, and feather duster worms) and the Alvinellidae, a family of deep-sea worms associated with hydrothermal vents.
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.
