A closeup of a cat's tongue from a side view as the cat licks her paw (with a single claw and pads visible). Numerous barbs (spines; filiform papillae) are clearly visible across the top surface of the tongue. this side view emphasizes the height of the barbs (the largest are almost half the thickness of the tongue), and shows that they're angled back only slightly. See the cropped version of this image for more detail on the tongue.
