“…Or, natural bioadhesives are adapted to adhere to native low energy surfaces. The first scenario seems physically and metabolically improbable due to the energetic costs but not out of the question; there are numerous marine species, 19 including bivalves 20 related to the common blue mussel, and sabellid tubeworms 21 related to sandcastle worms that chemically bore tubes into calcium carbonate rocks with acidic secretions. Although it is apparently biologically possible, to our knowledge, no evidence has been reported that mussels, barnacles, or sandcastle worms prepare surfaces for bonding by acid treatment.…”

The general topic of this review is protein-based underwater adhesives produced by aquatic organisms. The focus is on mechanisms of interfacial adhesion to native surfaces and controlled underwater solidification of natural water-borne adhesives. Four genera that exemplify the broad range of function, general mechanistic features, and unique adaptations are discussed in detail: blue mussels, acorn barnacles, sandcastle worms, and freshwater caddisfly larva. Aquatic surfaces in nature are charged and in equilibrium with their environment, populated by an electrical double layer of ions as well as adsorbed natural polyelectrolytes and microbial biofilms. Surface adsorption of underwater bioadhesives likely occurs by exchange of surface bound ligands by amino acid sidechains, driven primarily by relative affinities and effective concentrations of polymeric functional groups. Most aquatic organisms exploit modified amino acid sidechains, in particular phosphorylated serines and hydroxylated tyrosines (dopa), with high-surface affinity that form coordinative surface complexes. After delivery to the surfaces as a fluid, permanent natural adhesives solidify to bear sustained loads. Mussel plaques are assembled in a manner superficially reminiscent of in vitro layer-by-layer strategies, with sequentially delivered layers associated through Fe(dopa)3 coordination bonds. The adhesives of sandcastle worms, caddisfly larva, and barnacles may be delivered in a form somewhat similar to in vitro complex coacervation. Marine adhesives are secreted, or excreted, into seawater that has a significantly higher pH and ionic strength than the internal environment. Empirical evidence suggests these environment triggers could provide minimalistic, fail-safe timing mechanisms to prevent premature solidification (insolubilization) of the glue within the secretory system, yet allow rapid solidification after secretion. Underwater bioadhesives are further strengthened by secondary covalent curing.

“…Sipunculan borings are not restricted to limestones and may occur in other substrates (WARME 1975). Furthermore, a combined boring and burrowing behaviour may occur on an intraspecific level, as documented on Themiste hennahi (formerly lissum, STEARLEY &; EKDALE 1989).…”

The ichnogenus Balanoglossites MA.GDEFRAU, 1932 is re-described from its type area and is interpreted as part of a complex trace fossil comprising both burrow and boring components. The type ichnospecies, B. triadicus, consists of predominantly deep U-or Y-shaped tunnel elements, whereas B. ramosus n. isp. encompasses irregularly ramified galleries. Both ichnospecies occur frequently in firmground and hardground substrates with sporadic epikarst features. In the underlying softground, they may integrate into Labyrintichnus terrerensis UCHMAN ~; ~kLVARO, 2000, a network of irregular galleries and communicating shafts. On the omission surface, the tunnels are linked to elon~' gated or winding grooves in hard or firm substrates. Further elements of the complex trace fossd include lobate bur~ rows similar to Zoophycos and Rhizocorallium, mainly occurring in firmground and softground, shallow to deep Ushaped pouches and winding tunnels (Maeandropolydora sulcans VOIGT, 1965) in hard and firm substrates. Finally, some tunnel portions and well preserved top surfaces of the ichnofabrics are scattered with the faecal pellets Coprulus oblongus MAYER, 1952. C. oblongus has a rounded shape and a homogeneous structure and belongs to the Coprulidae n. ichnofam. Based on the numerous fingerprints preserved in the complex trace fossil, polychaete worms are identified as possible tracemakers, This is in accordance with the close combination of borings and burrows, a tunnel system highly variable in shape and size, blind ending side-branches and tunnel terminations, association with scolecodonts and exceptionally preserved polychaete remains. In addition, different commensals may have contributed to the modification of the complex trace fossil.Kurzfassung: Die Spurenfossil-Gattung Balanoglossites MAGDEFRAU, 1932 wird aus ihrem Typusgebiet neu beschrieben und als Teil eines komplexen Spurenfossils, das sowohl aus Grabgang-als auch ans Bohnmgskomponenten besteht, interpretiert. Die lchnotypus-Art, B. triadicus, besteht vorwiegend aus tief angelegten U-oder Y-fOrmigen Gangelementen, wohingegen B. ramosus n. isp. aus unregelm~iBig verzweigten G/ingen aufgebaut ist. Beide Spurenfossil-Arten kommen h~iufig in Fest-und HartgrOnden mit vereinzelten Epikarst-Erscheinungen vor. Im darunterliegenden Weichgrund kOnnen sie in Labyrintichnus terrerensis UCHMAN & ALVARO, 2000 ~ibergehen, einem Netzwerk yon unregelma6igen G~ngen und Verbindungssch/ichten. An Omissionsfl/ichen sind die G/inge mit langgestreckten oder gewundenen Furchen im harten oder festen Substrat verbunden. Weitere Elemente des komplexen Spurenfossils bestehen aus lobaten Grabg/ingen/ihnlich zu Zoophy¢os and Rhizocorallium, die vorwiegend in Fest-trod Weichgdinden vorkommen, flachen bis tief angelegten U-f'rrmigen "Taschen" und gewundenen Gangen (Maeandropolydora sulcans VOIGT, 1965) im harten und festen Substrat. Einige Gangabschnitte und gut erhaltene Schichtfl/ichen am oberen Abschluss des IchnogeAges sind mit den Kotpillen Coprulus oblong-us MAYER, 1952 Oberstreut. C. oblon...
