Why do barnacles never let go of sea creatures? Secret behind the grip that is stronger than any superglue

Barnacles, as crustaceans, employ a remarkable natural glue for tenacious adhesion to surfaces. Their cyprid larvae use temporary adhesives to explore, then secrete a permanent cement composed of complex proteins for underwater bonding. This ‘glue’ clears surfaces and forms a durable protein network, inspiring bioengineers to develop surgical glues and underwater sealants.
