As environmental stressors continue to amplify, Lucania parva, or Rainwater Killifish, are expected to outlast other species in unpredictably fast changing environments, as they are unique in their ability to tolerate multiple salinities. The objective of this research is to understand what affects L. parva’s ability to tolerate salinity and discover the limitations the species might have to tolerating it. Understanding this fish’s biology will help with the conservation of aquatic ecosystems in Florida. Preliminary data and early trends suggest that during early larval stages, L. parva are plastic but the extent of their plasticity is limited as they cannot survive as well in extreme salinities.
