Snake vision varies significantly amongst species. Some have keen eyesight and Other folks are only capable to distinguish light-weight from dim, though the vital trend is usually that a snake's Visible notion is suitable ample to track movements.[52] Usually, eyesight is very best in tree-dwelling snakes and weakest in burrowing snakes.
