Anatomical and histological studies on the eyes of brown bear (Ursus arctos horribilis)
The studied animals belong to the horribilis subspecies, Ursus arctos species, Ursidae family, and Carnivora order. The eyes of 2 brown bears were used. Anatomic examinations demonstrated that the dorsoventral length of the lens was 9.03 ± 0.37 mm for the right eye and 8.54 ± 0.11 mm for the left ey...
