Microplastics Affect Energy Balance and Gametogenesis in the Pearl Oyster Pinctada margaritifera [PDF]
Plastic pollution in the environment is increasing at global scale. Microplastics (MP) are derived from degradation of larger plastic items or directly produced in microparticles form (< 5 mm). Plastics, widely used in structures and equipment of pearl farming, are a source of pollution to the detriment of the lagoon ecosystem.

Calcitic Prisms of The Giant Seashell Pinna Nobilis Form Light Guide Arrays
The calcitic prisms in Pinna nobilis shells act as optical fiber arrays guiding ambient light with high resolution into the inner shell cavity by total internal reflection. This is attributed to the high refractive index of calcite along the optical axis of the prisms and the coverage of their interfaces by low refractive index organic sheaths ...

At Makemo Atoll (French Polynesia), the carapid fish Onuxodon fowleri lives in symbiosis with the black-lip pearl oyster Pinctada margaritifera. Although the symbiont seems to live inside its host bivalve by using it as a shelter, additional data are ...

Iridescent Color of a Shell of the Mollusk Pinctada Margaritifera Caused by Diffraction
Shells and pearls often show iridescent color. The cause of this phenomenon has been attributed to diffraction, both diffraction and interference, or interference alone. We used a shell of the mollusk Pinctada margaritifera, which shows very strong iridescent colors, to study how this color is produced in the layers of nacre in shells.

DNA fingerprinting of pearls to determine their origins. [PDF]
We report the first successful extraction of oyster DNA from a pearl and use it to identify the source oyster species for the three major pearl-producing oyster species Pinctada margaritifera, P. maxima and P. radiata. Both mitochondrial and nuclear gene
