| Abstract: | It is discussed that the microstructure and the microtopography for the shell of the crab and the lobster by X ray diffraction and scaning electron microscope. The CaCO 3 is calcite crystal in the shell of the crab. These calcium carbonate is distributed in the net structure composed of organic base. The dimension of net holl is about 15-25nm. After the portein is taken out in basic solution, the layered structure chitin is left over. Its repeat period is 0.96nm in the chitin. *communication |
