During the Battle for the Edge expansion pack, Astrid mention elephants while describing animal behavior.

"Cooperative pack behavior is how some animals and mammals survive. Musk Oxen and elephants will circle around their young to form a defensive barrier. Dolphins will travel in shoals to defend the group from shark attacks."
