writing a few lines on owl
Answers
Owls vary greatly in size, appearance, and coloration, but they all share one thing—the ability to turn their head 270 degrees. In order to perform this task, their necks contain 14 vertebrae, rather than the usual seven found in “normal” birds. While the neck vertebrae provide the range of movement, many animals—such as humans—would suffer traumatic arterial injuries and blood flow interruptions from such extreme motion.
In their attempt to understand how such capabilities exist, scientists have discovered that owls have special blood-pooling systems that collect blood to power their brains and eyes when neck movement cuts off circulation. Other awesome owl adaptations include alternative blood vessel routing and air-cushioned vessel casings to prevent rupture and stroke during violent head motion.
