The research highlighted that while the spines of sea urchins are made mainly of calcite, a very brittle and fragile material, the way nature optimises the “brick and mortar”-style architecture gives the spines additional strength. The guiding principle is to alternate hard (ie the brick) and soft (ie the mortar) layers as used by the sea urchin, When strength is ap... |
