多毛綱

多毛綱（學名：Polychaeta）是環節動物門下最大一個綱，目前轄下有超過80個科。

## 特點

這一綱的動物的身體一般呈圓柱狀，或背部略扁，身體分為口前葉、一般體節部分和尾節。其中體節上有成對的剛毛，神經節和後腎管。疣足（Parapodium）負責前進，甚至帶有鰓組織。有組多毛綱動物還擁有發達的感官；封閉式的血管系統。發育過程歷經螺旋卵裂和擔輪幼體（Trochophora）階段。繁殖能力強，通常為無性生殖，如裂殖生殖（Schizogamy）。

這一類動物主要為雌雄異體。雖然也有浮游的，但是大多生活在海底中，即所謂的底棲。一些品種在海底表面生活，可以自由運動。另一些則在沉積物中掘地洞。還有一些多毛綱動物行寄生生活。它們以微生物為食。目前有記錄的約有10,000種左右，體型從300µm到3m長。是環節動物最大的一個綱。

## 分類

目前生物學界普遍認同現時的多毛綱仍是一個並系群，也就是指本綱還有部分物種目前被分類到其他分類元去，以致本綱物種的演化圖仍未完整。舉例說：鬚腕動物門及螠蟲動物門的物種現時發現原來都應該放在多毛綱之下。

多毛綱物種在WoRMS大致可分成以下四大類：

- 螠蟲亞綱 Echiura
- 螠蟲目（Echiuroidea）
- Echiura 地位未定
- 足刺亞綱 Errantia
- 仙蟲目（Amphinomida）
- 磯沙蠶目（Eunicida）
- 葉鬚蟲目（Phyllodocida）：有29個科，尚可細分成五個亞目：
- 鱗沙蠶亞目（Aphroditiformia）
- 吻沙蠶亞目（Glyceriformia）及
- 沙蠶亞目（Nereidiformia）
- 葉鬚蟲亞目（Phyllodociformia）
- Phyllodocida 地位未定
- Polychaeta 地位未定
- 隱居亞綱 Sedentaria
- 頭結蟲下綱（Scolecida）：舊頭結蟲亞綱，又名尖錐蟲目。
- 小頭蟲目 Capitellida
- 管觸鬚下綱（Canalipalpata Rouse & Fauchald, 1997 non Linnaean）
- 帚毛蟲科（Sabellariidae Johnston, 1865）
- 纓鰓蟲目（Sabellida）：有六個科
- 海稚蟲目（Spionida）：有一個亞目
- 蟄龍介目（Terebellida）
- 磷沙蠶科（Chaetopteridae）Audouin & Milne Edwards, 1833
