爬行亞目
爬行亞目(學名:Reptantia)是1880年命名的十足目甲壳动物的兩個亚目之一,另一個是游泳亞目。這個亞目泛指在水裡依靠爬行而非游泳活動的十足目物種,包括有:海螯蝦科、短尾下目及其他知名的甲殼動物物種。

分類
在較舊的分類,爬行亞目連同游泳亞目是十足目兩個亞目:當中爬行亞目包括了在水裡爬行的物種;而游泳亞目包括了各種的蝦。1963年,Martin Burkenroad發現游泳亞目是並系群,而且不符合命名法則,所以把十足目重新分類為枝鰓亞目(Dendrobranchiata)及抱卵亞目(Pleocyemata)兩個亞目:抱卵亞目包含了舊有爬行亞目的所有成員,即蟹、龍蝦、螯蝦及其他,再加上真蝦下目(Caridea)及Stenopodidea[1]。儘管爬行亞目依然是個有效的单系群,但不再是亞目級,被視為不分類支序[2]。
解剖學
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.
