- •
The sperm whale skull amphitheatre is found to be a sandwich composite structure.
- •
Histology of the bone reveals the predominating layers have a substantial woven component.
- •
The middle layer is macroporous but contains larger quantities of primary bone.
- •
Nanoindentation reveals a stiffness of ca. 13 GPa in each layer.
- •
We relate the bone structure and histology to macro-mechanical properties, diving and crashing.
