Gray Marmot Video Stock Footage
Gray marmots are one of the largest palearctic species, weighing 4 to 6.5 kg, with some individuals reaching near 8 kg before hibernation. Body size varies based on the time of year (before/after hibernation), and with latitude and elevation. Overall, body size increases at higher latitude and elevation and decreases at lower latitudes and elevation. Gray marmots may loose up to 30% of body mass during long seasonal hibernation. They are short and stocky with brawny limbs and short tails. The total body length ranges from about 60 to 80 cm which includes the 13 to 15 cm long tail. Forefeet have 4 digits and strong claws for digging, while the hindfeet have 5 digits. On the dorsal (back) side, the fur is beige to tan with brown to black hairs or hair tips blended throughout giving the coat a gray appearance. The ventral (belly) side is a more orange-reddish brown. The length of the tail is much like the body but has a dark brown to black tip. The ears are small and round and light colored. The face is darker brown at the cheeks with lighter yellowish brown around the mouth. Albinism occurs in this species. Gray marmots are not known to exhibit sexual dimorphism (differences between males and females), but in most marmot species the adult males are larger than adult females. Gray marmots also have cheek glands and anal glands.
