Figure 4
Distribution and orientation of calcite and chitin in the side of club 6. (a)–(d) Region 1. (e)–(h) Region 2. (a), (e) Orientation of calcite (104). (b), (f) Orientation of calcite (110). (c), (g) Orientation of chitin (013). The inset in (c) shows how to interpret the figures: hue – orientation, saturation – projected degree of orientation (DoO), and value – natural logarithm to the total peak intensity in each point. (d), (h) RGB correlation of calcite and chitin: red – calcite (104) and (110), green – chitin (013), blue – chitin (110). The scale bars are 20 µm.
