Abstract In vitro mineralization of the gill cartilage ofLimulus (horse-shoe crab) has been reported previously (Eilberg et al. 1975). The present study demonstrates that cranial cartilage ofLoligo (squid) and odontophore cartilage ofBusycon (marine snail) also mineralize in vitro in hydroxypatite-metastable media, but not in carbonate-metastable media. In all three of these cartilages, light phase-contrast microscopy revealed that the mineral phase occurred in the form of spherical or ovoid granules ranging between 2 and 9 μm in diameter. During mineralization, the granules appeared successively in the perichondrium, in the matrix, and finally, within chondrocytes. Mineralization occurred more rapidly inBusycon odontophore cartilage which has a significantly higher content of phosphatidyl serine than inLimulus gill orLoligo head cartilages. In all tissues the mineralization process is related to temperature, taking place most actively at 37°C and only weakly at 50°C.
