Pretty sure we are the only animals with pink rings around our mouth. It’s flipping weird.
It probably helps with verbal language understanding as humans often use mouth movements to interpret words (see McGurk effect). But I still think it’s weird.
Big pink rings.
Batfish: “Yes! It is indeed my lips that are weird and make me feel self-conscious.”
[alt-text since Lemmy web UI doesn’t seem to have a way to add it to the image: photo of a red-lipped batfish. Besides its bright red lips, its head has a large protruding bulge, it and stands and walks on its four leg-like fins instead of swimming like a normal fish.]
