| Baikal is home to thousands of species of plants and animals, many of them endemic to the region. | WIKI |
| It hosts more than 1,000 species of plants and 2,500 species of animals based on current knowledge, but the actual figures for both groups are believed to be significantly higher. | WIKI |
| The watershed of Lake Baikal has numerous floral species represented. | WIKI |
| [35] More than 85 species of submerged macrophytes have been recorded, including genera such as Ceratophyllum, Myriophyllum, Potamogeton, and Sparganium. | WIKI |
| [35] Instead of vascular plants, aquatic flora is often dominated by several green algae species, notably Draparnaldioides, Tetraspora, and Ulothrix in water shallower than 20xc2xa0m (65xc2xa0ft); although Aegagrophila, Cladophora, and Draparnaldioides may occur deeper than 30xc2xa0m (100xc2xa0ft). | WIKI |
| [35] Except for Ulothrix, there are endemic Baikal species in all these green algae genera. | WIKI |
| [35] More than 400 diatom species, both benthic and planktonic, are found in the lake, and about half of these are endemic to Baikal; however, significant taxonomic uncertainties remain for this group. | WIKI |
| There are 236 species of birds that inhabit Lake Baikal, 29 of which are waterfowl. | WIKI |
| Two species of grayling (Thymallus baikalensis and T. brevipinnis) are found only in Baikal and rivers that drain into the lake. | WIKI |
| Fewer than 65 native fish species occur in the lake basin, but more than half of these are endemic. | WIKI |
| [35] Of particular note are the two species of golomyanka (Comephorus baicalensis and C. dybowskii). | WIKI |
| [47] Beyond members of Cottoidea, there are few endemic fish species in the lake basin. | WIKI |
| The most important local species for fisheries is the omul (Coregonus migratorius), an endemic whitefish. | WIKI |
| [48] The Baikal black grayling (Thymallus baicalensis), Baikal white grayling (T. brevipinnis), and Baikal sturgeon (Acipenser baerii baicalensis) are other important species with commercial value. | WIKI |
| The copepod Epischura baikalensis is endemic to Lake Baikal and the dominating zooplankton species there, making up 80 to 90% of total biomass. | WIKI |
| More than 350 species and subspecies of amphipods are endemic to the lake. | WIKI |
| [54] Among the "giants" are several species of spiny Acanthogammarus and Brachyuropus (Acanthogammaridae) found at both shallow and deep depths. | WIKI |
| [56] The vast majority of the Baikal ostracods belong in the families Candonidae (more than 100 described species) and Cytherideidae (about 50 described species),[56][58] but genetic studies indicate that the true diversity in at least the latter family has been heavily underestimated. | WIKI |
| [60] About 30 freshwater snail species can be seen deeper than 100xc2xa0m (330xc2xa0ft), which represents the approximate limit of the sunlight zone, but only 10 are truly deepwater species. | WIKI |
| Two of the most common species are Benedictia baicalensis and Megalovalvata baicalensis. | WIKI |
| [61] Bivalve diversity is lower with more than 30 species; about half of these, all in the families Euglesidae, Pisidiidae, and Sphaeriidae, are endemic (the only other family in the lake is the Unionidae with a single nonendemic species). | WIKI |
| [61][62] The endemic bivalves are mainly found in shallows, with few species from deep water. | WIKI |
| With almost 200 described species, including more than 160 endemics, the center of diversity for aquatic freshwater oligochaetes is Lake Baikal. | WIKI |
| [64] A smaller number of other freshwater annelids is known: 30 species of leeches (Hirudinea),[65] and 4 polychaetes. | WIKI |
| [64] Several hundred species of nematodes are known from the lake, but a large percentage of these are undescribed. | WIKI |
| More than 140 endemic flatworm (Plathelminthes) species are in Lake Baikal, where they occur on a wide range of bottom types. | WIKI |
| At least 18 species of sponges occur in the lake,[67] including 14 species from the endemic family Lubomirskiidae (the remaining are from the nonendemic family Spongillidae). | WIKI |
| [67] While the Baikalospongia species typically have encrusting or carpet-like structures, L. baikalensis often has branching structures and in areas where common may form underwater "forests". | WIKI |
| Baikal fishermen fish for 15 commercially used species. | WIKI |
