Wouri River
The Portuguese navigator and explorer Fernão do Pó or Fernando Poo, is believed to be the first European to explore the estuary of the Wouri, around the year 1472. The explorers noted an abundance of the mud lobster "Lepidophthalmus turneranus" in the Wouri River and named it "Rio dos Camarões", Portuguese for "River of Prawns", and the phrase from which the name Cameroon derived. The phrase"Rio dos Camarões" later became Camarones when the Spanish arrived in the region. Then, during the German protectorate in the country which started in 1884, the country's name changed to Kamerun before the Treaty of Versailles placed the country under French and British authority in 1919 which led to the final name "Cameroon".
