How much might an adult male Long-tailed Weasel outweigh a female?

Answer

By as much as 50%.

Sexual dimorphism in size is a characteristic displayed by the Long-tailed Weasel (*Mustela frenata*), meaning there is a noticeable difference in average size between adult males and females. Specifically, the data indicates that a mature male of this species might possess a body mass that exceeds that of a female by as much as 50 percent. This is reflected in their length measurements, where males reach total lengths up to 25 inches, while females are generally shorter, around 11 to 16 inches.
