| It is one of Europe's deepest and oldest lakes, with a unique aquatic ecosystem of worldwide importance, with more than 200 endemic species. | WIKI |
| Despite degradation from a variety of sources such as large-scale disposal of construction waste, major land conversion, disruption of water connections to Lake Ohrid, beach urbanization and loss of reed belts,[23] Studenchishte Marsh is still an important buffer to prevent lake eutrophication[25] and a key habitat for biodiversity, including relict plants and endemic species. | WIKI |
| Similar to Lake Baikal or Lake Tanganyika, Lake Ohrid harbors endemic species covering the whole food-chain, from phytoplankton and sessile algae (20 species; e.g., Cyclotella fottii), over plant species (2 species; e.g., Chara ohridana), zooplankton (5 species; e.g., Cyclops ochridanus), cyprinid fish (8 species; e.g., Pachychilon pictus), to predatory fish (two trout species; the Ohrid trout complex Salmo letnica, and "Belvica" Salmo ohridanus) and finally its diverse endemic bottom fauna (176 species; e.g. | WIKI |
| [34] Whereas the endemic species list cited above is based on morphological and ecological characteristics, some recent applications of molecular genetic techniques underline the difference of the fauna from common European taxa, as well as the old age of the lake. | WIKI |
| The reason lies very probably in the ideal adaptation of the endemic species to the specific conditions in the lake, such as low nutrient availability, good living conditions in greater depth thanks to high water transparency and oxygen content, as well as subaquatic spring inflows supplying cool and oxygen-rich water. | WIKI |
| Its oligotrophic waters conserve over 200 species of plants and animals unique to the lake, including algae, turbellarian flatworms, snails, crustaceans and 17 endemic species of fish including two species of trout, as well as a rich birdlife. | UNESCO |
