Triops
Triops, from Ancient Greek (), meaning "three", and (), meaning "face" or "eye", is a genus of small crustaceans in the order Notostraca (tadpole shrimp). The long-lasting resting eggs of several species of Triops are commonly sold in kits as pets. The animals hatch upon contact with fresh water. Most adult-stage Triops have a life expectancy of up to 90 days and can tolerate a pH range of 6 to 10. In nature, they often inhabit temporary pools.

背甲目（学名：Notostraca），其下单科鲎虫科（学名：Triopsidae），俗称“恐龍蝦”、“蝌蚪虾” 或“盾虾” ，其下鲎虫属（Triops）和冷鲎虫属/鳞尾虫属（Lepidurus）两属，自三叠纪以来在外形上都没有发生过显著的变化，均被视为活化石。鲎虫有着宽阔、平坦的背甲，甲下埋藏着鲎虫的头部，头上有一对复眼。鲎虫的腹部很长，呈节状，生有多对扁平足。尾节（英语：telson）的两侧是一对细长的尾叉。群间的表型可塑性（英语：Phenotypic plasticity）及繁殖模式的變異性導致種間辨識困難。鲎虫性杂食，生活在暂时性水池（英语：temporary pool）和浅塘的底部。

== Relatives and fossil record == The genus Triops can be distinguished from the only other living genus of Notostraca, Lepidurus, by the form of the telson (the end of its 'tail'), which bears only a pair of long, thin caudal extensions in Triops, while Lepidurus also bears a central platelike process. Only 24 hours after hatching they already resemble miniature versions of the adult form.
