Short-tailed Weasel or Stoat (Mustela erminea)

The Stoat, or Short-Tailed Weasel, is a small mammal in the northern hemisphere. Its black-tipped tail distinguishes it from other creatures, and its coat changes color from brown and white to snow-white to help it blend in with its surroundings. 

The Stoat can also reach up to 20 miles per hour despite its size. These adaptations help the Stoat avoid predators and hunt prey efficiently. 

It is a bold solitary hunter that often takes on prey much larger than itself. It prefers small mammals, birds, insects, and eggs, with voles being a primary food source. 

Its unique hunting technique involves a dance-like movement to mesmerize its prey and allow for attack. While the Stoat prefers to be alone, it will mate during mating season.
