Figures 1-8 in The elasmoid scales of teleosts: from structure to bioinspired materials
Figures 1-8. – Morphological aspects of elasmoid scales. Figures 1, 2. – Cycloid Scale of Carassius auratus. 1: Scale stained with alizarin red S. 2: SEM. The circuli (c) are more spaced in the exposed posterior field than in the overlapped anterior field. Insert: Note the presence of denticles (arrow) on the apex of the circuli. c: circuli; f: focus of the scale; r: radius. Figure 3. – Cycloid scale of Gaidropsarus vulgaris stained with alizarin red S. The circuli form regularly spaced out ridges concentrically disposed around the focus of the scale. The radii are oriented along the anteroposterior axis of the scale. Figure 4. – Ctenoid scale of Solea solea stained with alizarin red S. The posterior part of the scale is ornamented with denticles: the cteni (ct). The radii (r) are parallel and oriented along the anteroposterior axis of the scale. Figure 5. – SEM. Detail of the posterior part of the ctenoid scale of Coryphaenoides rupestris, which bears long fusiform cteni. Figure 6. – Posterior part of a scale of Solea solea stained with alizarin red S. At the margin of the scale, the most recent ctenii form acute denticles whereas the oldest progressively resorbed appear as truncated spines (asterisk). Figure 7. – Cycloid scale of Trisopterus luscus (Linnaeus, 1758) stained with alizarin red S. Numerous radii (r) span out from the focus (f) to the periphery of the scale. Figure 8. – Regenerating scale of Trisopterus luscus stained with alizarin red S showing an organization resembling that of the regular developed scales (Fig. 7). Figure 9. – Scale growth. Labelling in successive times with three different fluorochromes of a scale of Hemichromis bimaculatus Gill, 1862, fluoresceine: yellow-green, tetracycline: yellow and xylelol orange: red, reveals the successive mineral deposits during the scale growth. The unmineralized radii (r) are not labelled (micrograph: F.J. Meunier).
Figure 27 in The elasmoid scales of teleosts: from structure to bioinspired materials
Figure 27. – Etelis carbunculus Cuvier, 1828. Ground section. Polarised light. Black and white superimposed collagenous plies are characteristic of an orthogonal plywood-like structure. The basal plate (bp) is partially mineralized. Mandl corpuscles (arrow) are observed at the level of the front of mineralization. (micrograph: F.J. Meunier). Figure 28. – Macrourus berglax Lacepède, 1801. SEM. Broken freezed scale showing the lamellar structure of the basal plate. The direction of the collagen fibrils of adjacent layers are at right angle to one another forming an orthogonal plywood-like structure. Figure 29. – Poecilia reticulata Peters, 1859. TEM. Rapid freeze anhydrous techniques. Front of mineralization (mf) in the basal plate (bp). Figure 30. – Poecilia reticulata. TEM. Rapid freeze anhydrous techniques. The crystals are located in the spaces surrounding the cross-sectioned collagen fibrils that appear electrolucent. Figure 31. – Carassius auratus. TEM. Demineralized section. The superimposed plies of the basal plate (bp) are crossed by the TC fibres (tc) that arise from the hyposquamal scleroblasts (hs) and reach the external layer (el). ll: limiting layer Figure 32. – Carassius auratus. TEM. Rapid freeze anhydrous techniques. The characteristic aspect of the front of mineralization is due to the presence of the TC fibres (tc). It differs from the smooth one of Poecilia reticulata, which has no TC fibers (Fig. 29). Figure 33. – Poecilia reticulata. TEM. Mineralized corpuscles, Mandl corpuscles (mc), are located ahead of the front of mineralization. Figure 34. – Carassius auratus. TEM. Mandl corpuscles (mc) located ahead of the front of mineralization. Figure 35. – Trisopterus luscus. SEM. The front of mineralization is ornamented with fused Mandl corpuscles. Figure 36. – Cyprinus carpio. SEM. Mandl corpuscles and the mineralization front show a ridged surface due to the presence of TC fibres.

The contact between the ganoine and the dentine looks regular. Vascular apertures on the ganoine surface are visible (arrowheads); C: Detail of a ganoine ridge showing its contact with dentine (black arrowheads).
