Toco toucan beak

The beak of the toco toucan is integral to their vital social, feeding, foraging, and nest building behaviors. Since the toucan beak does not fully regenerate, it is evolutionarily favorable for it to have robust mechanical properties while still being light enough to allow flight. The beak makes up one-third of the toucan's body length, while contributing to less than three percent of the toucan's weight. The beak structure largely influences its mechanical properties and the lifestyle of the toucan. The beak's properties are increasingly becoming popular in the realm of biomimicry as several industries such as architecture, transportation, and protective equipment can utilize trends of the biological beak structure in manmade designs.
