Description
Ahlam Mohamed-Benhamu studies in 2025 what caffeine does to a freshwater snail at levels found in real waterways. Caffeine is a widespread stimulant and a growing pollutant in fresh water. The snail, Physella acuta, was exposed at a few set levels, and both adults and embryos were checked over a day and over a week.
Low levels sped up adult movement and exploring in the short term, but longer exposure pulled those behaviors back down. The highest level cut movement and feeding throughout. Embryos showed a dose linked rise in heart rate and formed faults at higher levels. The findings feed into ecological risk work, showing that a common drug like compound can shift both behavior and early development in a small water animal at levels already present in nature.
