多毛纲

<image>

多毛纲（学名：Polychaeta）是环节动物门下最大一个纲，目前辖下有超过80个科。

## 特点

这一纲的动物的身体一般呈圆柱状，或背部略扁，身体分为口前叶、一般体节部分和尾节。其中体节上有成对的刚毛，神经节和后肾管。疣足（Parapodium）负责前进，甚至带有鳃组织。有组多毛纲动物还拥有发达的感官；封闭式的血管系统。发育过程历经螺旋卵裂和担轮幼体（Trochophora）阶段。繁殖能力强，通常为无性生殖，如裂殖生殖（Schizogamy）。

这一类动物主要为雌雄异体。虽然也有浮游的，但是大多生活在海底中，即所谓的底栖。一些品种在海底表面生活，可以自由运动。另一些则在沉积物中掘地洞。还有一些多毛纲动物行寄生生活。它们以微生物为食。目前有记录的约有10,000种左右，体型从300µm到3m长。是环节动物最大的一个纲。

## 分类

目前生物学界普遍认同现时的多毛纲仍是一个并系群，也就是指本纲还有部分物种目前被分类到其他分类元去，以致本纲物种的演化图仍未完整。举例说：须腕动物门及螠虫动物门的物种现时发现原来都应该放在多毛纲之下。

多毛纲物种在WoRMS大致可分成以下四大类：

- 螠虫亚纲 Echiura
- 螠虫目（Echiuroidea）
- Echiura 地位未定
- 足刺亚纲 Errantia
- 仙虫目（Amphinomida）
- 矶沙蚕目（Eunicida）
- 叶须虫目（Phyllodocida）：有29个科，尚可细分成五个亚目：
- 鳞沙蚕亚目（Aphroditiformia）
- 吻沙蚕亚目（Glyceriformia）及
- 沙蚕亚目（Nereidiformia）
- 叶须虫亚目（Phyllodociformia）
- Phyllodocida 地位未定
- Polychaeta 地位未定
- 隐居亚纲 Sedentaria
- 头结虫下纲（Scolecida）：旧头结虫亚纲，又名尖锥虫目。
- 小头虫目 Capitellida
- 管触须下纲（Canalipalpata Rouse & Fauchald, 1997 non Linnaean）
- 帚毛虫科（Sabellariidae Johnston, 1865）
- 缨鳃虫目（Sabellida）：有六个科
- 海稚虫目（Spionida）：有一个亚目
- 蛰龙介目（Terebellida）
- 磷沙蚕科（Chaetopteridae）Audouin & Milne Edwards, 1833
