Ohridohauffenia drimica was a species of very small freshwater snail with an operculum, an aquatic gastropod mollusk in the family Hydrobiidae, the river snails. This species is now extinct.
This river snail was endemic to sediments within springs feeding the Drim River in North Macedonia, Europe. It was last seen in 1983, after which surveys failed to find this species in its original habitat when the Drim was drained of much of its water.
The bronze-winged duck also known as the spectacled duck, is a dabbling duck and the sole member of its genus Speculanas. It is often placed in Anas with most other dabbling ducks, but its closest relative is either the crested duck or the Brazilian duck, which likewise form monotypic genera. Together they belong to a South American lineage which diverged early from the other dabbling ducks and may include the steamer ducks.
The Drin is a river in Southern and Southeastern Europe with two distributaries one discharging into the Adriatic Sea and the other one into the Bojana River. Its catchment area extends across Albania, Kosovo, Serbia, Greece, Montenegro and North Macedonia. The river and its tributaries form the Gulf of Drin, an ocean basin that encompasses the northern Albanian Adriatic Sea Coast.
The broad whitefish is a freshwater whitefish species. Dark silvery in colour, and like a herring in its shape, its distinctive features include a convex head, short gill rakers, and a mild overbite. It is found in the Arctic-draining streams, lakes, and rivers of far eastern Russia and North America. Its prey includes larval insects, snails, and shellfish. It is eaten by humans and brown bears.
Cobitis ohridana is a species of ray-finned fish in the true loach family (Cobitidae). It is only found in Albania, Montenegro and North Macedonia. This fish was long believed to be part of the widespread Spined Loach.
Salmo dentex is a variety of trout, a freshwater fish in the family Salmonidae, found in the western Balkans. Until recently the identity, biological distinctness and species status of the dentex trout were not properly clarified, but genetic data now suggest it is not a monophyletic unit that could be distinguished from other salmonids as a separate species.
Bulinus hightoni is a species of freshwater snail, an aquatic gastropod mollusk in the family Planorbidae, the ram's horn snails.
Burnupia crassistriata is a species of small freshwater snail or limpet, an aquatic gastropod mollusk which was traditionally placed in the family Planorbidae, the ram's horn snails and their allies.
The Cahaba pebblesnail, scientific name Clappia cahabensis, is a species of very small freshwater snail, aquatic gastropod mollusks in the family Lithoglyphidae.
Cleopatra africana is a species of freshwater snails with an operculum, aquatic gastropod molluscs in the family Paludomidae.
Cleopatra exarata is a species of freshwater snails with an operculum, aquatic gastropod molluscs in the family Paludomidae.
The spiny river snail, scientific name Io fluvialis, is a species of freshwater snail, an aquatic mollusk in the family Pleuroceridae. This is the only species in the genus Io. This species is endemic to the USA.
Lanistes bicarinatus is a species of large freshwater snail in the family Ampullariidae, the apple snails. It is endemic to the Democratic Republic of the Congo, where it lives in river habitat. This snail is a common species. It is used locally for animal feed.
Leptoxis ampla, common name the round rocksnail, is a species of freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Pleuroceridae.
Leptoxis foremani, the interrupted rocksnail, is a species of freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Pleuroceridae.
Madagasikara is a genus of tropical freshwater snails with an operculum, aquatic gastropod molluscs in the family Pachychilidae.
Notopala sublineata is a species of large, freshwater snail with an operculum, an aquatic gastropod mollusk in the family Viviparidae, the river snails or mystery snails. This species is endemic to Australia.
The Snake River physa snail, scientific name Physella natricina, is a species of freshwater snail, an aquatic gastropod mollusk in the family Physidae. This species is endemic to Idaho in the United States.
The rough hornsnail, scientific name Pleurocera foremani, is a rare species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Pleuroceridae.
The River Sateska is located in the south-west of North Macedonia. Currently a tributary of Lake Ohrid, it originally flowed directly into the River Black Drim but was re-routed in 1961/2. It now accounts for 39.36% of the Lake Ohrid watershed and is consequently one of its most important tributaries.
