Triops is a genus of small crustaceans in the order Notostraca (tadpole shrimp). Some species are considered living fossils, with a fossil record that reaches back to the late Carboniferous, . One species, Triops longicaudatus, is commonly sold in kits as a pet.
Yet the truth is the that these living fossils are nothing more than creatures that God created on day one or their recent micro-evolutionary (not macro) relatives. They are still alive today because the Earth is Young and so is mankind!
