Range and Identity
Lucania parva occurs along Atlantic and Gulf waters into Mexico and can ascend inland, including the Rio Grande and Pecos region of Texas and New Mexico. Coastal and inland records should retain their salinity when known. The common name alone does not establish freshwater-only occurrence.
Habitat and Behavior
Fish occupy quiet water near vegetation and can occur in mangrove settings. The immediate plant cover and water movement are useful observations. A broad estuary label may conceal the sheltered margins actually occupied, while an inland record can represent a different set of local conditions.
Food and Life History
Copepods, insect larvae, worms and mollusks are recorded foods. The maximum reference is seven centimeters total length. This is a nonannual killifish, so obligatory annual adult disappearance is not part of the described life cycle. No maximum mass is calculated from the upper length.
Field Note
Record measured salinity when available rather than infer it from the name of the water body. This species’ coastal and inland records can involve quite different conditions.
