How does the average weight of an Atlantic walrus male (*O. r. rosmarus*) compare to a Pacific walrus male (*O. r. divergens*)?
Answer
Atlantic males average around 900 kilograms, significantly less than Pacific males
There is a notable morphological difference in size between the two main recognized subspecies of walrus. The Pacific walrus (*O. r. divergens*), inhabiting the Bering and Chukchi Seas, is substantially larger, with males having the capacity to surpass 2,000 kilograms in body mass. In contrast, the Atlantic walrus males (*O. r. rosmarus*) are considerably smaller on average, with recorded weights typically centering around 900 kilograms. This size disparity, along with differences in tusk length and skull structure, contributes to their subspecific classification.
