European bison are smaller than their American counterparts, with adult females ranging from 300-540 kg and adult males from 400-920 kg. They have shorter hair in the neck region as well, which further contributes towards a smaller appearance. However, their pelage appears nearly the same color as their American relatives, and their horns are well-developed. Males and females are dimorphic not only in body size but in skull growth and allometry, as well as in some physiological parameters. Pictures of European bison are available in Sokolowski (1983).
