Limpopo River Australopithecus fossils from 3.5 million years ago. St Vincent Whitshed Erskine, later Surveyor General for South Africa, traveled to the mouth of the river in 1868-69. A Zambezi shark ("Carcharhinus leucas") was caught hundreds of kilometres upriver at the confluence of the Limpopo and Luvuvhu Rivers in July 1950. Zambezi sharks tolerate fresh water and can travel far up the Limpopo. In 2013, approximately 15,000 Nile crocodiles were released into the river from flood gates at the nearby Rakwena Crocodile Farm.

In 1845, W.D. Cooley, examining Pereira's notes, concluded the term "Zambezi" derives not from the Bisa people, but rather from the Bantu term "mbege"/"mbeze" ("fish"), and consequently
