Range and Identity
Fundulus rathbuni is recorded from the Dan, Neuse, Cape Fear, Pee Dee and Catawba regions. The Dan belongs to the Roanoke system and the Catawba to the Santee system, so both local river and larger drainage names are useful when comparing records.
Habitat and Behavior
Adults usually occur over sand or mud in backwaters and pools of creeks and small to medium rivers. These are relatively sheltered channel settings. The presence of nearby flowing water does not mean that the fish necessarily occupies the strongest riffle current.
Food and Life History
The narrative source reports an upper length of 9.6 centimeters total length, exceeding the eight-centimeter summary header. The larger published value is retained. The species is not an annual seasonal killifish, and an independent maximum weight is not established.
Field Note
Keep the measurement convention and drainage with the record. Differences between source headers and accompanying accounts should remain visible rather than causing the larger supported size to disappear.
