Body size was measured in 15 adult moose, hair colouration was described in 46, and horn shape in 78 individuals. According to morphometric characters, the East Siberian moose (Alces americanus pfizenmayeri) of Yakutia occupies a position intermediate between A. a. buturlini and A. a. cameloides and has morphological features characteristic of a subspecies. Four colour variations have been identified in the body colouration. The most common colouration is light brown (43.4%). In head colouration, 5 colour shades are detected, only brown colouration is common in both sexes. There are some sex differences in head colouration, females being coloured in lighter tones, vs males in darker tones. In males, 4 types of horn shape are identified: shovel-shaped horns with a divided shovel, with a narrow shovel and long ramifications, shovel-shaped with an undivided shovel and stag-shaped horns. Specimens with shovel-shaped antlers with a divided shovel are the most frequent (82.0%). A. a. buturlini has been recorded from central Yakutia.
