Issued by British Honduras (now Belize), this ½ cent definitive stamp features the Tilapia mossambica, a freshwater fish native to Africa, introduced for aquaculture in many tropical regions. The fish is beautifully illustrated against a deep blue aquatic background, highlighting its striped scales. The stamp bears the royal cypher “E II R” of Queen Elizabeth II, denoting colonial authority. It forms part of a mid-20th-century series showcasing the colony’s marine and natural life, printed under the British administration before independence.
