Canalipalpata ( German )

provided by wikipedia DE

Canalipalpata ist der Name einer Ordnung meist sessiler und röhrenbauender, als Filtrierer lebender Vielborster (Polychaeta) in der Unterklasse Palpata, die in Meeren weltweit zu finden sind.

Merkmale

Die Canalipalpata besitzen weder Zähne noch Kiefer. An ihren am Prostomium sitzenden Palpen befindet sich eine Wimpernrinne mit zahlreichen Cilien, mit denen aus dem Wasser aufgefangene kleine Nahrungspartikel, meist Detritus, zum Mund transportiert werden. Durch die Wimpernrinne haben die Palpen einen u-förmigen Querschnitt. Lediglich bei den Siboglinidae, die sich ausschließlich über eine Symbiose mit Bakterien ernähren und deshalb keine Nahrung von außen benötigen, fehlen diese Wimpernrinnen.

Verbreitung, Lebensraum und Lebensweise

Die Spionida sind in Meeren weltweit verbreitet und leben sowohl auf weichen als auch auf harten Substraten, wo sie ihre Wohnröhren bauen und so als sessile Tiere leben. Sie ernähren sich als Filtrierer von Detritus und Phytoplankton, das sie mit ihren Palpen aus der Meeresströmung auffangen und durch Wimperntätigkeit an den Palpen zum Mund transportieren.

Systematik

Die Ordnung Canalipalpata bildet laut der Systematik nach Rouse & Fauchald von 1998 mit ihrer Schwestergruppe, den Aciculata, die Unterklasse Palpata.

Laut dieser Systematik gehören zur Ordnung Canalipalpata die Unterordnungen Sabellida, Terebellida und Spionida mit nachfolgenden Familien:

Sabellastarte magnifica, magnificent feather duster worm

Canalipalpata, also known as bristle-footed annelids or fan-head worms, is an order of polychaete worms, with 31 families in it including the suborder Sabellida (families Serpulidae (tubeworms) and Sabellidae (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.[1] 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.[2]

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).[3]

Use in aquaria

Many species of Canalipalpata are visually attractive. Fanworms and Christmas tree worms (a type of serpulid) are recommended as species for beginners to keep in a marine aquarium.[4]

Canalipalpata ( Portuguese )

provided by wikipedia PT

Canalipalpata G.W.Rouse & K.Fauchald, 1997 é uma ordem de anelídeos da classe Polychaeta (poliquetas) que inclui 31 famílias de filtradores, maioritariamente marinhos, agrupadas em 3 subordens, entre as quais Sabellida (com os anelídeos com penacho branquial em forma de leque Serpulidae e Sabellidae) e Alvinellidae (uma família que inclui espécies de águas profundas associadas às fontes hidrotermais).[1]

Descrição

As espécies que integram o taxon Canalipalpata não apresentam maxilares ou dentição,[1] sendo na sua grande maioria animais filtradores dos fundos marinhos. Apresentam palpos sulcados e recobertos por cílios que são utilizados para transportar as partículas de alimento até à boca. Contudo, os cílios e os sulcos não estão presentes na família Siboglinidae.[2]

O registo fóssil mais antigo conhecido de membros do grupo Canalipalpata é um fóssil da espécie Terebellites franklini, encontado na Formação Clouds Rapids da Terra Nova, datado do Cambriano médio (série St. David).[3]

Muitas espécies de de Canalipalpata são visualmente atractivas, em especial as poliquetas-leque do grupo Sabellida e da espécie Spirobranchus giganteus (um Serpulidae), sendo utilizadas em aquariofilia e recomendadas para a decoração de aquários marinhos.[4]

A ordem Canalipalpata inclui as seguintes subordens e famílias:
