Adiël Klompmaker explores the taxonomy and population distribution of the mud shrimp Glypturus. These shrimp are commonly found in Miocene and Holo-Pleistocene deposits on both Atlantic/Caribbean and Pacific coasts of Panama, but today they are absent on the Pacific side. Klompmaker has found two new shrimp species, one of which is from Panama. Come see him this afternoon at poster booth 256!
