| Synonyms: Pettancylus petterdi (Johnston, 1879), Pettancylus australicus (Tate, 1880), Ferrissia wautieri (Mirolli, 1960), Ferrissia clessiniana (Jickelli, 1882) |
| Common name: fragile ancylid, freshwater limpet |
| Taxonomy: |
| Family: Ancylidae |
| Order: Basommatophora |
| Class: Gastropoda |
| Phylum: Mollusca |
| Native range: North America |
| Date of introduction/first record: First recorded in August 2007 (Semenchenko and Laenko 2008). |
| Vector: Semenchenko and Laenko (2008) argue that shipping from the territory of Ukraine is the most likely vector of invasion of F. fragilis into waterbodies of Belarus. |
| Records in Belarus: Several localities along the Pripyat River (Semenchenko and Laenko 2008). |

| Potential ecological impacts: Smith (1967) wrote that “Wherever found, they [ancylid snails] are likely to outnumber all other gastropods, and thus undoubtedly exert an appreciable effect on the ecology of trematode parasites in a given locality”. In its native range in North America, F. fragilis serves as intermediate host for many trematodes, including such taxa as Diplodiscidae (Megalodiscus temperatus), Strigeoidea, Spirorchiidae and Echinostomatidae. One can expect that in invaded areas the limpet also gets involved into the life cycles of various trematodes. |
