What biological distinction does the Least Weasel (*Mustela nivalis*) hold among living carnivores globally?
Answer
It is the smallest living carnivore worldwide
The Least Weasel, scientifically designated as *Mustela nivalis*, holds a specific superlative title within the order Carnivora based on its physical dimensions. It is recognized as the smallest true weasel and, critically, the smallest living carnivore across the entire globe. This diminutive size dictates its ecological niche, allowing it to access extremely small prey inaccessible to its larger relatives like the Long-tailed Weasel or the Stoat/Ermine. While other species differences revolve around tail length or coat color changes, the defining trait separating *M. nivalis* is its record-breaking small stature.
