Description
The blackspotted topminnow has an elongate body up to 9.7 centimeters long. It is brownish yellow to olive green on its upper side and has a wide, dark lateral band and distinct dark spots. The male has longer fins than the female and the fins of the male may take on a yellowish color during breeding. This species is very similar to the blackstripe topminnow (Fundulus notatus), which also has a dark lateral band. It can be distinguished from F. notatus by its darker, more numerous spots. The two may hybridize. In Fundulus olivaceus, the gill slit extends the dorsal to the uppermost pectoral fin ray. The distance from the origin of the dorsal fin to the end of the hypural plate is less than the distance from the origin of the dorsal fin to the preopercle or occasionally about equal to that distance. The mouth is sightly supraterminal.
