A Lesson in Survival
In the day-to-day grind of the animal kingdom, a myriad of adverse conditions, coupled with predictable predators, gives the term “survival of the fittest” a whole new meaning.

How do these amazing creatures of nature not sustain brain damage? “For one, they have built-in shock absorbers,” says Green. “They’ve also got their tongues. Woodpecker tongues wrap all the way around the skull, going up the back and over the top, fitting snugly into one end of the hyoid bone.”
