WEBMar 1, 2005 · Nacre in Bivalvia has a terraced growth and the crystals’ three axes are co-oriented. Interestingly, Nautilus (Cephalopoda) nacre shows a mixed behaviour in which towered and terraced growth occurs simultaneously in adjacent locations [5]. Similar to bivalves, the three main crystallographic axes of Nautilus nacre crystals are parallel.
The Biology and Culture of Pearl Oysters (Bivalvia: Pteriidae)
WEBThe "pearl oysters", genus Pinctada,are char-. acterized by a long straight hinge, with the long axis of the shell at right angles to the hinge. The left valve is a little deeper than the right and there is a byssal notch on each valve at the base of the anterior lobe (Rao 1970).
