Apparently, you are repsonding to my statement that there are *no*
examples of aquatic (or even semit-aquatic) animals (living or
extinct) that are bipedal.
I should have prefaced my statment to include "evolved bipedalism
in such an aquatic habitat".
Clearly, you were aware that penguins' ancestors inherited their
bipedalism from their theropod dinosaur ancestors, (who were already
fully bipedal land animals).
Or perhaps you weren't aware of that.
(as an interesting side-point to this, there are *no* known aquatic
non-avian dinosaurs known from the fossil record. Go figure...).
