Suckerins are block‐copolymer‐like structural proteins constituting the building blocks of the strong squid sucker‐ring teeth. Here, recombinant suckerin‐19 is processed into biomaterials spanning a wide range of elasticity, from very soft hydrogels to stiff films with elastic modulus in the gigapascal range. The elasticity is controlled by the interplay between the β‐sheet content and induced di‐tyrosine crosslinking.
