It was created in 1934 and its current boundary contains an area of . The largest lake in the reserve is Lake Kronotskoye, which covers an area of . It also has Russia's only geyser basin, plus several mountain ranges with numerous volcanoes, both active and extinct. Due to its often harsh climate and its mix of volcanoes and geysers, it is frequently described as
Extinct in the wild among aquarists for some time, but hobbyist stocks have declined quite a lot more recently, placing its survival in jeopardy. However, the ultimate purpose of preserving biodiversity is to maintain ecological function. When a species exists only in captivity, it is ecologically extinct. Reintroduction is the deliberate release of species into the wild, from captivity or relocated from other areas where the species survives. This may be an option for certain species that are endangered or extinct in the wild. However, it may be difficult to reintroduce EW species into the wild, even if their natural habitats were restored, because
