Yellowmargin Triggerfish (Pseudobalistes flavimarginatus)

The scientific and administrative event driving the definitive regular issue is the final phase of the systematic mid-century taxonomic survey mapping the aquatic ecosystems of the Horn of Africa. Textually classified under the scientific designation "PSEUDOBALISTE", this high-value installment chronicles the diverse marine life thriving within the complex coral reefs of the Gulf of Tadjoura and the Bab-el-Mandeb strait.

Historically, this definitive release served an important geopolitical and administrative function for the Côte Française des Somalis. By processing these detailed ichthyological catalogs through the international mail channels of the Universal Postal Union, the civil government officially registered the rich natural resources of its coastal waters, broadcasting the distinct maritime identity and oceanographic profile of the strategic East African territory.
