What mammal can move it's eyes independently, thus allowing it to has a complete 360 degree field of vision?

I am not sure that there is any animal has full 360 degree vision (i.e. it cannot see directly behind it).

Animals that have independent movement of the eyes are ones that do not have binocular vision, and so they would exclude most carnivores, since binocular vision is very useful for hunting.

The commonly quoted animals I believe is the horse.

A chameleon can. Go and watch one in the zoo. Their eyes really do move independently. I don't know how their brains process the separate information to give the 360 degree view but he's your man.

Horses tend to trip up over things on the floor without putting their heads down to look so I doubt they have 360 degree vision.

It is a mammal,(chameleons are reptiles) found only in the northern hemisphere from Norway to eastern Canada.

Sorry, misread the question. Don't think there are any mammals that have wonky eyes.

Maybe I'm wrong try this;

Transgenic Mice?

Ha, ha..... James Gallway.

No, I was serious about the mice. They are messing with mice and vision at the moment. Can't get the press release to load though.

But their eyes don't move independantly, that would look weird.

Give up?

It is the moose. According to The National Geographic Channel special on the moose - all varieties -   move their eyes independently to detect movement. This is because their eyes are set so far out on their skull that they are nearly at 360 degrees already. Recent work, that was not cited in the program, has discovered that the eyes can rotate back to see in back of their hindquarters.

Since I saw it on TV I am not going to believe it until the scientific abstract is available on line BUT ... hey, I thought it was interesting.

The squirrel has a 358° field of vision.

Don't they need to have a hole in the back of the head? Either that or an eye extended out, like a snail or something

Yes, you already mentioned it. The eye is locate at the widest point of the moose skull,  beyond the taper of the back of the skull.

'tis a mere nothing - it is probably due to the massive excess of iron in your brain and all of your body that causes you wool to turn pink and your tongue to protrude from your mouth.
