Giraffe necks
Sure, some members of this list are cliché, but for good reason. Giraffes have as many vertebrae in their necks as we do (seven), yet theirs are doing a whole lot more. The elegant giants use these long necks to get their purple tongues around lofty leaves, but they also use them in “necking” fights over mating and for sentry duty, according to the Giraffe Conservation Foundation.
