Hypothesis

Is the critically endangered limpet Rhodacmea filosa still extant in the Mobile River Basin?

Conclusion

Rhodacmea filosa is not extinct and persists in a Coosa River tributary.

Supporting Evidence

  • Rhodacmea filosa was rediscovered in a tributary of the Coosa River.
  • Genetic analyses confirmed the taxonomic validity of Rhodacmea filosa.
  • Three surviving populations of Rhodacmea represent distinct evolutionary lineages.

Takeaway

Scientists found a freshwater limpet thought to be extinct still living in a river, which is great news for its survival.

Methodology

The study involved genetic and morphometric analyses of limpets from different populations.

Limitations

The sample size was small, limiting the ability to perform more detailed statistical analyses.
