The "bayou killifish", Fundulus pulvereus, and the "marsh killifish", F.
confluentus, may turn out to be the same species once "those who decide"
look more closely. The big diffs are that pulvereus is found mostly to the
west of Mobile Bay, and confluentus is found exclusively to the east of
Mobile Bay; and, pulvereus is usually found in brackish/salty waters while
confluentus is usually found in brackish/fresh waters. But these are inexact
differences when you look closely. To me they're nearly identical in
physical appearance, but that can be deceiving.
