Camels Don't Mind Spines In Their Cacti

This pair of dromedary camels, Baby and Nessie, are snacking on cactus and clearly don’t mind the spines. It hurts, but they can handle it. Camels have adapted and inside a camel’s mouth, small cone-shaped protrusions called papillae guide the animal’s chew.

The key is to avoiding being poked by the spines, so camels pivot their chew and slide the needles vertically down their throats.
