Range and Identity
Menidia extensa is the retained identity for the Waccamaw Silverside. The compiled range centers on Lake Waccamaw, rather than every lake containing a small silver fish. Other silversides require their own identification and should not supply additional locality or size records automatically.
Habitat and Behavior
Adults commonly form large schools near the surface over dark sandy bottom. Surface skipping has been observed and interpreted as predator avoidance. That interpretation should remain distinct from a direct observation of a particular predator pursuing every skipping fish.
Food and Life History
The reported upper length is eight centimeters total length, with 4.8 centimeters as common. Age evidence indicates spawning after the first winter, with relatively few fish surviving through a second winter. This is a population observation, not an exact lifespan for every individual.
Field Note
Record schooling behavior and an identifiable individual when possible. A whole-school image can document surface activity well while leaving the fine features needed for species identification unresolved.
