Look closely. There are tubular structures on the side of an octopus’s head. They expand and I assume this has some respiratory function. It surely isn’t the mouth. That would be a single structure. I think most animals have one mouth and two nostrils. Hey, maybe I’m wrong and there’s one nose and one mouth. But fish have gills and they are paired. Right? Well, the point is for you to look. I sure did. I have too many octopus pictures to put in another post. Except, I’m fascinated.
This guy has his tentacles in his mouth and nose? Both sides and I count six tentacles. For me this is a first. I don’t know the behavior but I can tell you that I have never seen a girl admit to or pick her nose in public. It’s a boy octopus.
