Figure 5From: Hierarchical super-structure identified by polarized light microscopy, electron microscopy and nanoindentation: Implications for the limits of biological control over the growth mode of abalone sea shellsScanning electron microscopy image of the nacre super-structure. Scanning electron microscopy of a 60 μm section in orientation A. Top, overview image showing the transition between prismatic and nacreous layers. Center, super-structure in the size range of 20 μm in the nacreous layer. Domains of homogeneous grey level are formed by stacks of adjacent nacre platelets. Bottom, boundary between two domains which form the super-structure.Back to article page
