The way Ollie got her name - Before she arrived, I told my husband he could name our octopus. Without even a pause, he said "Ollie, Ollie Octopus". I thought it was a fine name. And after Ollie turned out to be a girl, it was still a fine name.
Like most of our octo owners, I assumed that I had a male. (It's very difficult to determine the sex of a bimac. ) Then, when I saw the eggs, I knew Ollie was a female and began referring to "she" and "her".
