lol...you ever notice in nature, the male is usually the "prettier" one? On that basis, I'm guessing the blue one is the dude. Could be wrong, don't know a thing about those creatures, but with every other animal I can think of with a male/female difference, the male is the more striking of the two.
Very Cool orca. I love seeing other people appreciate the small details, which are actually big picture. I.e. people usually don't like bugs, and fail to see their beauty and purpose in the world we live in.
Always a pleasure to share here. Junk, You are correct. The male is the vivid blue one. And derkaderk, You always show true appreciation to mother nature in all of your posts. Love you guys!:)
