There seems to be a bit of confusion about how classification in the animal kingdom works, so I’m happy to help clear that up.
Examples of walruses:

From Marler Blog: https://www.marlerblog.com/files/2017/07/walrus-04-300x200.jpg
From the New York Post: https://thenypost.files.wordpress.com/2017/06/unnamed2.jpg?quality=90&strip=all&w=618&h=410&crop=1
Things that are not walruses (pay attention, this will be on the test):
Human beings of any gender, regardless of what size they are or how much they weigh.

A beautiful, desirable woman with an abundance of people who want to spend time with her, date her, fuck her and do delightfully, deliciously kinky things to her.
