Bioadhesion Models from Marine Invertebrates: An Integrated Study - Biomechanical, Morphological, Biochemical, Molecular - of the Processes Involved in the Adhesion of Cuvierian Tubules in Sea Cucumbers (Echinodermata, Holothuroidea)

Abstract

Cuvienan tubules are specialized adhesive defense organs occurring exclusively in some sea cucumber species. Cuvierian tubule adhesion is instantaneous. Our results suggest that the adhesive is in the form of a low molecular weigth precursor protein in the secretory granules of the adhesive cells. Upon release, these proteins instantly polymerize with no enzymatic curing required. The adhesive thus constituted has a composition unique among marine organism bioadhesives and forms relatively strong bonds. The unique characteristics of sea cucumber Cuvierian tubule adhesive could offer novel features or performance characteristics for applications as underwater adhesives.
