“…The average diameter of the tubules changes from 44 μηι (close to core) to 18 μπι (close to periphery). This gradation in pore diameter has been observed in the foam structure of porcupine quill [16] and channels in the structure of sucker rings from Dosidicus gigas [17]. Although the horn is mineralized, due to the extensive porosity, the overall density (by weight and dimension measurements) is ~ 1000 kg/m 3 .…”

Boxfish have a rigid carapace that restricts body movement making them slow swimmers. Some species of boxfish {Lactoria cornuta) have lightweight horns that function as a form of defense. The boxfish horns are nearly hollow and have an intricate hierarchical structure. The structural organization and compressive properties of the boxfish horns are described here to understand the mechanical behavior and damage mechanisms.

Biological materials display complicated three-dimensional hierarchical structures. Determining these structures is essential in understanding the link between material design and properties. Herein, we show how diffraction tomography can be used to determine the relative placement of the calcium carbonate polymorphs calcite and aragonite in the highly mineralized holdfast system of the bivalve Anomia simplex. In addition to high fidelity and non-destructive mapping of polymorphs, we use detailed analysis of X-ray diffraction peak positions in reconstructed powder diffraction data to determine the local degree of Mg substitution in the calcite phase. These data show how diffraction tomography can provide detailed multi-length scale information on complex materials in general and of biomineralized tissues in particular.

“…In 2009, the cover of ‘ Advanced Materials ’, volume 21 (4), January 26 featured a photo of squid sucker rings and a scanning electron micrograph of nanoporous structures of a sucker tooth. The article that the cover picture was connected with stated that the nanoporous material was entirely proteinaceous and did not contain chitin . The arrangement of parallel tubes in the structure was considered to increase the bending stiffness of the tooth and to reduce ‘the probability of catastrophic structural failure by introducing a potential crash‐arresting mechanism at the boundaries between two constituent materials (in this case, protein and seawater)’ .…”

Nanoporous Structures Similar to Those Reported from Squid Sucker Teeth are also Present in Egg Shells of a Terrestrial Flatworm (Platyhelminthes; Rhabditophora; Geoplanidae) from Hachijojima (Izu Islands, Japan)

Shells of the egg cocoon of a terrestrial planarian (Diversibipalium sp.) from Hachijojima were found to be composed of a lattice of parallel nanotubes of ca. 120 nm diameter oriented perpendicular to the shell's surface. The arrangement of the porous proteinaceous tubes closely resembles that has recently been reported from the sucker teeth of squid and to date is the only other example of this kind of structure. Although the array of nanotubes undoubtedly contributes to the stiffness of the shell and helps protecting the embryo, questions such as to how the planary worm produces the array of nanotubes and what exactly their chemical and physical properties are versus those of the squid sucker tooth still remain to be answered.
