爬行亚目
爬行亚目(学名:Reptantia)是1880年命名的十足目甲壳动物的两个亚目之一,另一个是游泳亚目。这个亚目泛指在水里依靠爬行而非游泳活动的十足目物种,包括有:海螯虾科、短尾下目及其他知名的甲壳动物物种。

分类
在较旧的分类,爬行亚目连同游泳亚目是十足目两个亚目:当中爬行亚目包括了在水里爬行的物种;而游泳亚目包括了各种的虾。1963年,Martin Burkenroad发现游泳亚目是并系群,而且不符合命名法则,所以把十足目重新分类为枝鳃亚目(Dendrobranchiata)及腹胚亚目(Pleocyemata)两个亚目:腹胚亚目包含了旧有爬行亚目的所有成员,即蟹、龙虾、螯虾及其他,再加上真虾下目(Caridea)及Stenopodidea[1]。尽管爬行亚目依然是个有效的单系群,但不再是亚目级,被视为不分类支序[2]。
解剖学
The name Reptantia means "those that walk", and contains those 十足目s whose primary mode of locomotion is to walk along a surface using the pereiopods rather than swimming through the water with the pleopods. Despite this, many reptants are able to propel themselves through the water, and many non-reptants can and will walk.
