The Florida Fundulus From Tony

I received a package of preserved fishes from Tony, finally delivered to me through campus mail on Tuesday. The one individual from the apparent intergrade creek really does look exactly intermediate between the F. lineolatus and F. escambiae also in the package, variously from SC and FL. The specific locale is just to the east of the Appalachicola River which is a famous biogeographic boundary between very similar species to the east and west, so the fact that this intergrade killifish population seems to exist is no real surprise. But we still have to get decent DNA sequences from it, so we'll see.
