It is hard to guess what a Long-tailed weasel weights. But we have the answer:
An adult Long-tailed weasel (Mustela frenata) on average weights 191 grams (0.42 lbs).
The Long-tailed weasel is from the family Mustelidae (genus: Mustela). It is usually born with about 3 grams (0.01 lbs). They can live for up to 7.08 years. When reaching adult age, they grow up to 23 cm (0′ 10″). Usually, Long-tailed weasels have 6 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The long-tailed weasel (Mustela frenata), also known as the bridled weasel or big stoat, is a species of mustelid distributed from southern Canada throughout all the United States and Mexico, southward through all of Central America and into northern South America. It is distinct from the short-tailed weasel, also known as a “stoat”, a close relation that originated in Eurasia and crossed into North America some half million years ago.
