Range and Identity
Etheostoma thalassinum is restricted to the Santee drainage in the compiled account. The state boundary does not divide this river system into different species ranges. Conversely, another Carolina drainage needs separate occurrence evidence even when it lies nearby.
Habitat and Behavior
The documented habitat consists of rocky riffles in creeks and small to medium rivers. These shallow flowing areas differ from sheltered muddy backwaters. Recording the actual riffle and bottom material helps explain the fish’s immediate setting within a larger river landscape.
Food and Life History
The reported maximum is eight centimeters total length, with six centimeters as a common reference. The retrieved summary does not establish an independent maximum mass, detailed diet or specific spawning sequence. Similar ecology in another darter is not treated as direct evidence for this species.
Field Note
Include the tributary and larger Santee connection with a record. Basin identity can be more informative than a nearby town or the common color-based name alone.
