Thirty species of snapping shrimp in the genus Alpheus live off the Isthmus of Panama, the land bridge that connects North and South America. Morphological and genetic data group these shrimps into 15 pairs of species, with the members of each pair being each other’s closest relative. In each case, one member of the pair lives on the Atlantic side of the isthmus, while the other lives on the Pacific side.  Shrimp Panama.jpg What type of speciation likely led to this distribution of species? Did the land bridge predate the snapping shrimp living in this region or did the shrimp predate the land bridge?
