Hey , all you folks who are interested in animal skulls... I was looking at my skull collection and noticed: Every prey animal I have: deer, antelope, sheep, goat, horse, camel (but not rodents or marsupials) have enclosed eye sockets, including primates. Every carnivore skull I have, that I looked at ( can't find the badger and skunk) has open eye sockets, except the meerkat and the ferret. The only other mongoose I have ( a binterong) and the other "weasels" I have ( related to ferrets) have open eye sockets too.
So I wonder why the difference? What about their lifestyle would require closed eye sockets?
Maybe because meerkats are prey animals as well as predators, they have some of the same characteristics as other prey animals??
"Open eye sockets" means that the place the eyeball sits in the skull is not completely surrounded by bone.
