Triops cancriformis

Along with T. longicaudatus, and L. apus, this is the most widespread and common of the triops.  Next to T. longicaudatus, it is the most studied.  It also shares the honor of being considered a rice crop pest with T. longicaudatus. Notable in that it is probably the “proto-triops” from which all the others have evolved in the past 200 or so million years, it is also the oldest known living species of any animal.
