“…Taylor and Layman (1972) and Carter (1980) classified the microstructures of the shell at the SEM level and reported a range of mechanical properties and functions of bivalve shells. Li et al (2017) also reviewed the mechanical features of the crossed lamellar structure. According to those reports, this structure was found to be the hardest but also the least elastic shell microstructure.…”

The Great East Japan Earthquake and accompanying tsunamis occurred on 11 March 2011, causing huge damage to marine organisms. The invasive naticid gastropod Laguncula pulchella (Euspira fortunei), which was introduced with the imported clam Ruditapes philippinarum from China and Korea, survived the earthquake. The "growth break line" observed on the shell surface in over 90% of the individuals collected in Matsushima Bay and Matsukawa-ura Lagoon after the tsunamis was examined by scanning electron microscopy. Each shell presented three layers before and three after the growth break. However, the fracture surface consisted of five layers-two prismatic and three crossed lamellar-around the growth break line. This suggests that shell formation temporarily ceased following the tsunamis and that the five-layered shell may have developed in response to the stress caused by the tsunamis. The newly formed middle layer became thinner after the "tsunami break," which may be the result of a rapid change in the mineralization process, including rapid shell growth and/or repair. These results suggest that the damage to and forcible removal of habitats by the tsunamis was stressful for L. pulchella. A decrease in or the cessation of shell formation after a tsunami may be a common phenomenon in mollusks that inhabit tidal flats.

“…Bivalves are a widely spread molluscan class with more than 10 000 species [1], and they are characterized by an ability to build shells of different sizes, forms and structures. Bivalve shells are very durable compared with inorganic geological forms and have been important to research in the fields of bioengineering and bionics for dozens of years [2,3]. In nature, shells are formed by a biologically controlled process, viz., biomineralization, which results in a composite material that is composed of approximately 95% calcium carbonate (aragonite and calcite) and less than 5% organic components (shell matrices) [4].…”

Molecular characterization of a whirlin-like protein with biomineralization-related functions from the shell of Mytilus coruscus

et al. 2020

Mollusc shells are produced from calcified skeletons and have excellent mechanical properties. Shell matrix proteins (SMPs) have important functions in shell formation. A 16.6 kDa whirlin-like protein (WLP) with a PDZ domain was identified in the shell of Mytilus coruscus as a novel SMP. In this study, the expression, function, and location of WLP were analysed. The WLP gene was highly expressed and specifically located in the adductor muscle and mantle. The expression of recombinant WLP (rWLP) was associated with morphological change, polymorphic change, binding ability, and crystallization rate inhibition of the calcium carbonate crystals in vitro. In addition, an anti-rWLP antibody was prepared, and the results from immunohistochemistry and immunofluorescence analyses revealed the specific location of the WLP in the mantle, adductor muscle, and myostracum layer of the shell, suggesting multiple functions for WLP in biomineralization, muscle-shell attachment, and muscle attraction. Furthermore, results from a pull-down analysis revealed 10 protein partners of WLP in the shell matrices and a possible network of interacting WLPs in the shell. In addition, in this study, one of the WLP partners, actin, was confirmed to have the ability to bind WLP. These results expand the understanding of the functions of PDZ-domain-containing proteins in biomineralization and provide clues for determining the mechanisms of myostracum formation and muscle-shell attachment.

“…The crossed-lamellar structure (a complex hierarchical structure comprising an ordered arrangement of thin lamellas composed of laths of nano-sized fibers) located in the outer parts of shells and the inner nacreous aragonite layers have been the most frequently examined. The reasons are brilliant mechanical properties as well as a possibility to reproduce these materials as components in synthetic, ceramic-based composites [5][6][7][8][9][10][11]. The calcite layers forming the columnar prisms elongated along the growth direction were investigated as well [12,13].…”

Anisotropy of Mechanical Properties of Pinctada margaritifera Mollusk Shell

et al. 2020

View full text Add to dashboard Cite

The mechanical properties such as compressive strength and nanohardness were investigated for Pinctada margaritifera mollusk shells. The compressive strength was evaluated through a uniaxial static compression test performed along the load directions parallel and perpendicular to the shell axis, respectively, while the hardness and Young modulus were measured using nanoindentation. In order to observe the crack propagation, for the first time for such material, the in-situ X-ray microscopy (nano-XCT) imaging (together with 3D reconstruction based on the acquired images) during the indentation tests was performed. The results were compared with these obtained during the micro-indentation test done with the help of conventional Vickers indenter and subsequent scanning electron microscopy observations. The results revealed that the cracks formed during the indentation start to propagate in the calcite prism until they reach a ductile organic matrix where most of them are stopped. The obtained results confirm a strong anisotropy of both crack propagation and the mechanical strength caused by the formation of the prismatic structure in the outer layer of P. margaritifera shell.
