Is there a lot of variation in body shape, color, or other characteristics between the different fundulus species found throughout the U.S.? For example I have seen Northern, Southern, and - I believe - Eastern variants of the fundulus dispar.
I understand that the spawning behavior/time/environment could be different between the locations. Northern species would be adapted to the freezing winters whereas the Southern wouldn't be.
Is the spawning characteristic the only real difference between the fundulus species in different locations?
