Stoat

The dimensions of the stoat are variable, but not to the extent as the least weasel. Sexual dimorphism in size is pronounced, with males being 1.5-2.0 times the weight of females.[16] On average, males measure 187–325 mm (7.4–12.8 in) in body length, while females measure 170–270 mm (6.7–11 in). The tail measures 75–120 mm (3.0–4.7 in) in males and 65–106 mm (2.6–4.2 in) in females. In males, the hind foot measures 40.0–48.2 mm (1.57–1.90 in), while in females it is 37.0–47.6 mm (1.46–1.87 in). The height of the ear measures 18.0–23.2 mm (0.71–0.91 in) in males and 14.0–23.3 mm (0.55–0.92 in). The skulls of males measure 39.3–52.2 mm (1.55–2.06 in) in length, while those of females measure 35.7–45.8 mm (1.41–1.80 in). Males weigh 258 grams (9.1 oz), while females weigh less than 180 grams (6.3 oz).
