Abstract: The beak of the Humboldt squid Dosidicus gigas represents one of the hardest and stiffest wholly organic materials known. As it is deeply embedded within the soft buccal envelope, the manner in which impact forces are transmitted between beak and envelope is a matter of considerable scientific interest
These findings may serve as a foundation for identifying design principles for attaching mechanically mismatched materials in engineering and biological applications.
