Pectinariidae, or the trumpet worms or ice cream cone worms, are a family of marinepolychaete worms that build tubes using grains of sand roughly resembling ice cream cones or trumpets. These structures can be up to 5 centimetres (2 in) long. The earliest pectinariid fossils are known from the Cretaceous.[1]
Pectinariids are sessile burrowing tube dwellers, which can be found in fine-grained sediment. They position the wider end of their tube downwards, and use their stout golden setae for digging while they use tentacles for sorting the particles which they ingest. Half of the particles which the worm digs through are excreted as pseudofaeces.[2]
Generaedit
The systematics of the pectinariids have been the subject of some debate. Previously, only two genera have been recognized,[3] but three subgenera have been elevated to full genera by some scholars.[4][5]
Amphictene Savigny, 1818 - sometimes included as subgenus in Pectinaria
Cistenides Malmgren, 1866 - sometimes included as subgenus in Pectinaria
Lagis Malmgren, 1866 - sometimes included as subgenera in Pectinaria
