| Abstract: | The orbit of the bowhead whale is quite modified, shows much more variation in comparison to that of the better studied mammals,
and is composed of the maxillary bone, lacrimal bone, frontal bone, temporal bone, zygomatic bone, parietal bone and sphenoid
bone. The whale’s eyeball usually protrudes beyond the bony orbital rim, based on the observation of this study. Our observation
in this study that the whale has an enclosed orbit differs from that of Prince (1956), who mentioned that the whale has an
open orbit.
