Species Profile
The dense hydrobe, scientific name Aphaostracon pycnum, is a species of small freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Cochliopidae.
Dense Hydrobe faces significant threats from habitat degradation and water pollution in its freshwater environments. Urban development and agricultural runoff have contaminated many of the clean, well-oxygenated waters this species requires for survival. Climate change is also altering water temperatures and flow patterns in its native range.
Key Facts
