钵水母纲

钵水母纲（学名：Scyphozoa）是刺胞动物门的一个纲。例如水母、海蜇、海月水母、霞水母等。

这类水母早在寒武纪就已出现，直到现在。

## 语源

钵水母纲的学名Scyphozoa源于古希腊语的skyphos（σκύφος），意思就是杯状的物品。

## 特征

一类不具缘膜的大型水母。伞缘缺裂呈瓣状，胃腔中有满生刺细胞的胃丝。

一般有营裂体的无性生殖世代（附着的水螅体钵形，构造近似海葵）和雌雄交配的有性世代（游泳的水母体伞形，由其内胚层产生生殖细胞）交相更迭的世代交替现象。

## 分类

钵水母纲有：

- †目 Byroniida
- 冠水母亚纲 Coronamedusae
- 冠水母目 Coronatae
- 圆盘水母亚纲 Discomedusae
- 旗口水母目 Semaeostomeae
- 根口水母目 Rhizostomeae

锥石目（Conulariida）是一个化石分类单元，可能也是钵水母纲的成员，但其从属具广泛争议。

## 下属分类

本纲包括以下目：

Coronatae Rhizostomeae Semaeostomeae

目的地位未定的科：

Carinachitidae Circonulariidae Conulariellidae Conulariidae Conulariopsidae Corumbellidae Hexangulaconulariidae Kimberellidae Olivooidae Pomoriidae Rhizostomitidae
