The gray wolf or grey wolf (Canis lupus), often known simply as the wolf, is the largest wild member of the Canidae family.
Adult wolves are 105–160 cm (41–63 in) in length and 80–85 cm (32–34 in) in shoulder height. The tail is ⅔ the length of the head and body, measuring 29–50 cm (11–20 in) in length. The ears are 90–110 millimeters (3.5–4.3 in) in height, and the hind feet are 220–250 mm.
Gray wolves have very dense and fluffy winter fur, with short underfur and long, coarse guard hairs. Most of the underfur and some of the guard hairs are shed in the spring and grow back in the autumn period.The winter fur is highly resistant to cold; wolves in northern climates can rest comfortably in open areas at −40° .Hair length on the middle of the back is 60–70 mm. Hair length of the guard hairs on the shoulders generally does not exceed 90 mm, but can reach 110–130 mm.Wolves howl to assemble the pack (usually before and after hunts), to pass on an alarm (particularly at a den side), to locate each other during a storm or unfamiliar territory and to communicate across great distances.
