The Maura pen shell (Atrina maura) is a large bivalve mollusk native to the eastern Pacific, particularly along the coasts of Mexico, Central America, and northern South America. Recognized for its elongated, triangular shell, the Maura pen shell inhabits sandy and muddy substrates in shallow coastal waters. The species is valued both for its edible flesh and its shell, which is sometimes used in crafts. The top countries engaged in Maura pen shell fishing include Mexico, Ecuador, and Peru, where small-scale and artisanal fisheries harvest the species, often by hand or with simple tools. In Mexico, particularly in the Gulf of California, the Maura pen shell supports local economies, though overfishing and habitat degradation have led to concerns about population declines. As a result, some regions have implemented management measures to ensure the sustainability of this important fishery.
