Islamia trichoniana is a species of small freshwater snail with a gill and an operculum, an aquatic gastropod mollusc or micromollusc in the family Hydrobiidae. [1] [2] [3]
I. trichoniana is endemic to Greece, where it is restricted to Lake Trichonida, an ancient, deep, oligotrophic lake [4] in the south Adriatic-Ionian region of the country. [1]
This species is currently classified by the IUCN as critically endangered and possibly extinct. While it was once found throughout Lake Trichonida, it is currently known from only one location on the northeast shore of the lake. It is threatened by habitat destruction, as intensive agricultural practices in the neighbouring area lead to water pollution and eutrophication of the lake and the excessive abstraction of water for irrigation purposes causes a drop in water level. [1] [5] [6]
Lake Ohrid is a lake which straddles the mountainous border between the southwestern part of North Macedonia and eastern Albania. It is one of Europe's deepest and oldest lakes, with a unique aquatic ecosystem of worldwide importance, with more than 200 endemic species.
Lake Trichonida is the largest natural lake in Greece. It is situated in the eastern part of Aetolia-Acarnania, southeast of the city of Agrinio and northwest of Nafpaktos. It covers an area of 98.6 square kilometres (38.1 sq mi) with a maximum length of 19 kilometres (12 mi). Its surface elevation is 15 metres (49 ft) and its maximum depth is 58 metres (190 ft).

Graecoanatolica vegorriticola is a hydrobiid gastropod endemic to littoral habitats in Lake Vegorritis and Lake Patron. It is listed as Critically Endangered by the IUCN, mainly due to habitat loss as a result of the eutrophication of Lake Patron, and the effects of pollution upon the remaining suitable habitat near Lake Vegoritida. When described, it was reported that the species was found in great abundance on the margins of Lake Vegorritis, but in 2006 only the remnants of the original population were found.
