Chemical Secrets Of Starfish Stickiness
Starfish face a tricky challenge: They secrete adhesive from their tube feet to avoid getting swept away by currents, but the material’s stickiness must be reversible so the animal can move around to seek out food. Now, researchers in Belgium report the first analysis of a major protein constituent of these sticky secretions, a step toward developing starfish-inspired adhesives that are reversible on underwater or wet surfaces (Proc.
