The tadpole shrimp (Triops) is a well-known ‘living fossil’ whose fundamental morphology has been unchanged for over 170 million years. Thus, tadpole shrimps are suitable subjects for the study of morphological stasis. We were able to obtain samples of three species ofTriops(T. granarius, T. longica...
