无螯下目(Achelata),也称无螯虾下目,是十足目抱卵亚目下的一个下目。
描述
[编辑]无螯下目得名于其下的虾没有螯这一事实,“Achelata”来自希腊语,其中α-即a-为“没有”之意,χηλή即chela为“螯”之意。它们拥有扩大的触须,幼体则为特殊的叶形幼体。[2]
分类
[编辑]无螯下目包含龙虾科和蝉虾科这两个现存科,[3] 另外还有坎虾科和三脊虾科这两个已灭绝科。[1]
- 龙虾科 Palinuridae Latreille, 1802
- 蝉虾科 Scyllaridae Latreille, 1825
- †坎虾科 Cancrinos Beurlen, 1930
- †三脊虾科? Tricarina Feldmann et al., 2007
两个现存科的化石记录都可以追溯到白垩纪。[4][5] 另外两个化石科都只有一个属,[6] 其中坎虾科生活于侏罗纪至白垩纪之间。[5] 也有人认为无螯下目的化石记录可以追溯到3亿4100万年前。[7]
