The Siberian mouse (Mus musculus sibiricus) is a subspecies of the house mouse (Mus musculus) that is native to the vast and harsh terrain of Siberia. They are incredibly adaptable animals, able to survive in the extremely cold temperatures and short summers of this unforgiving environment. While they are an interesting species of mouse in their own right, one Siberian mouse that gained international recognition was Veronika.
Veronika's remarkable longevity and unusual characteristics have made her an interesting subject of study in the scientific community. Researchers have studied her behavior, physiology, and genetics to gain insights into the factors contributing to her exceptional lifespan and overall health. siberian mouse veronika
