The tube feet of echinoderms attach to surfaces via suction adhesion.

"Besides mollusks, echinoderm tube feet make use of suction adhesion, as do a wide variety of other aquatic systems--either as the only attachment mechanism or in combination with others. Among terrestrial systems one thinks first of wet ones--frogs for instance. But the mechanism finds use even in arboreal mammals." (Vogel 2003:427)

Bioinspired products and application ideas

Application Ideas: Suction-cup mounted assemblies with better adhesion, marine and other coatings with better adhesive properties (durability), marine infrastructure that relies on suction under certain tidal conditions, suction-based boat moorings to decrease damage from anchors.

Industrial Sector(s) interested in this strategy: Manufacturing, coatings, marine siting, boat moorings
