Additionally seals have 40% body fat, but walruses have 20%?

That seems suspicious.

I didn't know my body fat so I just guestimated 20 to immediately be flashbanged by the image of a walrus.

I consider myself on the skinny side so it was a surprise to be sure.

The body fat content for many animal species varies a lot throughout the year based on migration, food availability, and (sometimes) hibernation. So it depends on when you measure.
