Three-cornered Conch (Strombus tricornis)

Issued in the early 1960s as part of the Shells of the Red Sea series of the French Somali Coast (Côte Française des Somalis), this stamp commemorates the Three-cornered Conch (Strombus tricornis), a marine gastropod found in the warm tropical waters of the Indian Ocean and the Red Sea region. The series was designed to highlight the remarkable diversity of marine life inhabiting the coastal waters of the territory and to promote interest in natural history and marine science.

By featuring the Three-cornered Conch, the issue emphasized the ecological richness of the Red Sea and the importance of marine biodiversity. The stamp celebrated the region's maritime heritage while encouraging appreciation of the unique shell species that contribute to the natural beauty and biological significance of one of the world's most diverse marine environments.
