Ear pinna is found in which animal??

Answer 1

Almost every animal in the world has ears, ears as in "some type of biological organ or mechanism to take in and interpret vibrations in the air." If you're specifically saying "the flappy dome-shaped muscle" ear known as a Pinna then I believe that is an exclusively mammalian feature.
