The order Notostraca comprises the single family Triopsidae, containing the tadpole shrimp or shield shrimp. The two genera, Triops and Lepidurus, are considered living fossils, having not changed significantly in outward form since the Triassic. They have a broad, flat carapace, which conceals the head and bears a single pair of compound eyes. The abdomen is long, appears to be segmented and bears numerous pairs of flattened legs. The telson is flanked by a pair of long, thin caudal rami. Phenotypic plasticity within taxa makes species-level identification difficult, and is further compounded by variation in the mode of reproduction. Notostracans are omnivores living on the bottom of temporary pools and shallow lakes.

  • I Notostraca sono un ordine di piccoli crostacei appartenenti alla classe Branchiopoda. L'ordine comprende una sola famiglia (Triopsidae) suddivisa in due generi. Gli appartenenti al genere Triops hanno due occhi composti ed un solo occhio naupliare posto fra gli altri due. La morfologia esterna apparentemente non ha subito modifiche da quella del Triops cancriformis nel Triassico 220 milioni di anni fa. Il Triops cancriformis potrebbe essere la più antica specie animale ancora vivente. I membri dell'ordine ormai estinto dei Kazacharthra sono molto simili, essendo discendenti di questo stesso ordine.
