men hvordan faelder en rur laget der ligger imellem denselv og substratet??? :?og det gör den vel? jeg har set fler billeder pa nettet hvor de smider exoskelletet.
Rurer cementerer sig ved sekretioner fra hoved regionen som ungdyr setter de sig fast med hovedet nedad og metamorfosen foregaar i den position resten af livet og rurer har noe legendarisk klaebestof.

Nature shows us another path to developing biological adhesives. The buoy barnacle (Dosima fascicularis) produces a special adhesive which it uses to attach itself tightly to flotsam. This super-adhesive is so strong that it is almost impossible to break down into its constituent parts using ordinary solvents. Another special property it has is its ability to cure under water. Researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Bremen are now trying to find out which amino acid components make up the relevant proteins. “Once we’ve done that, the next step will be to recreate the adhesive proteins in the laboratory,” says Dr. Ingo Grunwald, expert for biological adhesives at the IFAM. Such bioadhesives are primarily of interest for medical applications, for example to close incisions or to replace or support the pins and screws used to treat bone fractures.
