“…Each of these components was evaluated to determine the relative quantities of mineral, organic, and water. Full individual scutes, separated collagen tissue (from the base of the scutes, obtained by polishing away the scutes on the surface), and highly mineralized tissue (taken from the horn [32] and assumed to be similar to the mineralized plates on the scutes) were rehydrated in saline solution for 24 h, and tested by thermogravimetric analysis (TGA) using a SDT Q600 TGA (TA Instruments, New Castle, DE, USA) at a ramp rate of 10°C/min and a range of 20-800°C. This procedure has previously been reported for the determination of water, mineral, and protein in biomaterials [33].…”

Tessellations (surface architectures of arrays of hard tiles) are common in natural and man-made designs. Boxfishes (Ostracioidea) are almost completely encased in a tessellated armor and have evolved a plethora of cross-sectional carapace shapes, yet whether the scutes constructing these exhibit comparable variation is unknown. Using high-resolution microCT and semi-automatic segmentation algorithms, we quantitatively examined thousands of scutes from 13 species of diverse body form. A cluster analysis revealed that certain scute types are associated with specific carapace regions independent of carapace shape. Scute types differentiate between carapace edges and flat regions, as well as between the head region with many carapace openings and the more consistently closed abdominal region, pointing at a constructional commonality or constraint shared by all boxfish species. However, the dimensions of edge scutes varied systematically with carapace shape (e.g., scute aspect ratio tended to increase with decreasing carapace height). This suggests that protection is maintained across body forms by managing scute- and carapace-level mechanisms for increasing bending resistance. Future studies on other taxa are necessary to understand whether these architectural principles are specific evolutionary solutions for building a boxfish carapace or whether they are shared by other biological systems that serve a similar protective function.
