Best answer!
A veterinarian student posted this answer to that same question 5 years ago:
Many ungulates (hoofed mammals) can see nearly all the way behind them due to the position of the eyes on the sides of the head. This is an evolutionary adaptation to being the prey of many predators - you have more chance of escaping being something's dinner if you can see it creeping up behind you. Horses, deer, antelope and so on all fit into this category.
Chameleons and seahorses are able to move each of their eyes independently - they can swivel their eyes so that they point directly backwards, and thus see behind them without turning their heads.
Owls can see behind them without turning their bodies, since their heads can swivel almost 180 degrees. This is an adaptation to the fact that they cannot move their eyes - they are so huge that there is no room inside the skull for muscles to move them. They must therefore turn their heads to change their line of sight.

Only Praying Mantis which is an INSECT can turn its head 360 degrees.
Other than the above OWL can turn about 270 degrees - Owls can't move their eyes around in their sockets so they must move their head. Owls have fourteen neck bones. Their neck bones let an owl turn its head 270 degrees in both directions. This is not quite a full turn. Unlike us, an owl can turn its head around to see what is sneaking up behind it.
Eagles also have fourteen vertebrae in their necks, and can turn their heads about 210 degrees.
But both of them are birds
There is no animal who can turn the head more 225 degrees
Some sites say a rabbit can see behind itself because of being able to turn its head 360, so there's a contradiction. Some sites say they can move their eyes independently. I'm on my way to the fair, so will have to delve into the subject more thoroughly later, but I'm glad you asked. I learn something new here every day...most of it useless, but learning just the same !!!! Love you! :D
