This is a list of Russian animals that are considered extinct, 3 species have unique shapes

INDONEWTRAVEL.COM - The Russian Ministry of Natural Resources and Environment in September 2021 conducted a census of the animal world and found that there are about 11 species of animals and fish that once inhabited certain areas are no longer seen in the wild. This condition causes them to be put on the 'possibly extinct' list, the last category before being considered completely extinct.

This species can still be seen in national parks and zoos, but not in the wild. These species include the European marine sturgeon, crested ibis, western capercaillie, Bunting Jankowski, monk seal, onager, and Przewalski's horse. This includes the European bison (or zubr) and the Siberian tiger, which was on the verge of extinction in the first half of the 20th century due to hunting. Here are some of them summarized by INDOWTRAVEL from the Russian Beyond page.

1. Przewalski's horse

Przewalski's horse used to inhabit Asia, the Kazakh forests and southern parts of West Siberia. It was last seen in the wild in Mongolia in 1969.

Przewalski's horse, otherwise known as the P-horse, is named after Nikolai Przewalski (pronounced "shuh-val-skee"), a Russian explorer. He was the first to discover this sub-species of horse in 1870.

One version surrounding the disappearance of Przewalski's horse species relates to the harsh winter of 1944-1945. At that time the temperature dropped to minus 40 degrees Celsius with fierce daily snowstorms.

2. Baltic Sturgeon

The Baltic sturgeon used to inhabit Lake Ladoga, as well as the rivers flowing into the Blatic, White, and Black Seas. Russian sturgeon (Acipenser gueldenstaedtii), also known as diamond sturgeon or Danube sturgeon, is a species of fish in the family Acipenseridae.

Russian sturgeon can grow up to 235 cm long and weigh 115 kg. Adult Russian sturgeons breed very slowly. Due to extensive and highly intensive industrial fishing, as well as hydro development around spawning habitats, fish are nowhere to be seen. There is also no attempt to revive the species through artificial breeding.

3. Crested Ibis

The Crested ibis was once widespread from the central Priamurye Region to several provinces in China.

Today, it can only be found in Russia's Khanka reserve, on the border with China. It is the only bird species of the genus Nipponia of the family Threskiornithidae. This bird has become extinct from most of its natural habitat. Until the 19th century, this bird can be found in various places in East Asia, but the population dwindled drastically in the early 20th century.
