Owls do not have eyeballs in the traditional sense; instead, they have eye tubes or cylinders that are elongated and do not move in their sockets like human eyeballs do. This unique eye structure allows owls to have large eyes relative to their body size. This helps owls see in low light conditions.
Because their eyes are fixed in their sockets, owls must rotate their heads to look around.
They are capable of turning their necks up to 270 degrees.
