Pinctada maxima, commonly known as the silver-lipped oyster or the giant pearl oyster, is a large marine bivalve mollusk found in warm waters of the Indo-Pacific region. It is notable for producing high-quality pearls, particularly the stunning white and gold varieties. This species can grow up to 30 centimeters in size and is often cultivated in pearl farms. These oysters inhabit shallow coastal waters, typically in sandy or muddy substrates. They play a vital role in their ecosystem by filtering water and providing habitat for various marine organisms. Pinctada maxima is also significant in the aquaculture industry, contributing to both economic and cultural aspects of pearl production.
