The Pond mud snail (Omphiscola glabra) is typically found in soft, nutrient poor waters with few other aquatic animals or plants. These include freshwater marshes, small ditches, temporary pools or seepages that dry up or significantly diminish in summer. These water-bodies are challenging habitats, which in the past were regarded as inferior wildlife habitats and were typically converted into productive agricultural land or improved visually for landscape reasons. Historically, this species was widespread throughout acidic lowland areas of England, Wales and Scotland, as far north as Perth. A recent survey has shown that this species has been lost from 64% of historical sites in Scotland.
