Abstract
The skeleton of spines and tests of the species of sea urchins Strongylocentrotus intermedius, Mesocentrotus nudus, Scaphechinus mirabilis, and Echinocardium cordatum from the Sea of Japan is composed of a spongy stereom, consisting of calcite with a high content of magnesium. It was found that the tests and spines of the skeletons of sea urchins are composed of calcium–organic composite materials inlaid with other metals: Mg, Fe, Zn, and Rb. In the four species of sea urchins studied, the strength and other mechanical properties of the tests and spines differ and depend on the chemical composition and structural organization of their components. It was shown that the content of volatile substances correlates with their fragility or elasticity. It is revealed that the chemical composition of the tests of two species of the spherical sea urchins S. intermedius and M. nudus indicates significant differences between these two species of sea urchins.
