Going fishing tomorrow in the waters outside of a Swedish island called Marstrand. Very much looking forward to it. Got me thinking about blue mussels – usually pretty good bait for sea wolf. It has become a darling of the biomimicry crowd. For instance – the mussels are attach to each other and to the rock and sea weed through a very strong adhesive. Unlike our glues, it sets underwater and doesn't need a primer, an initiator, or a catalyst to work. Could revolutionize paints and coatings, and enable surgeons to operate without sutures. See more examples here.
