Ontario Lacus is a lake composed of methane, ethane and propane near the south pole of Saturn's moon Titan. Its character as a hydrocarbon lake was confirmed by observations from the Cassini spacecraft, published in the 31 July 2008 edition of Nature. Ontario Lacus has a surface area of about 15,000 square kilometers (5,800 sq mi), about 20% smaller than its terrestrial namesake, Lake Ontario in North America. In April 2012, it was announced that it may be more like a mudflat or salt pan.

The word is taken from the Herero language. An omuramba provides occasional standing pools of water and more fertility than in the surrounding sand plains. Some specific omiramba are named: Eiseb, Rietfontein, Epukiro, Omatako. They mostly start in the central parts of Namibia and run into the central parts of Botswana.

The Hoanib is one of the 12 ephemeral seasonal rivers in the west of Namibia, where it used to be the border between northern Damaraland and Kaokoland. Its length is 27 kilometres (17 mi). With the low population density in the area, the oasis character of the river valley and the relatively high wildlife population of the Hoanib, like in the case of the Hoarusib, its valley is one of the last true wilderness areas in Namibia. One of the last settlements of desert elephants, it is characterised by strong wind and water eroded, weathered stone deposits. Inflows of Hoanib are Aap River, Otjitaimo River, Ombonde, Ganamub, Mudorib and Tsuxub.
Desert elephants or desert-adapted elephants are not a distinct species of elephant but are African bush elephants that have made their homes in the Namib and Sahara deserts in Africa. Previously they were classified as a subspecies of the African bush elephant, but this is no longer the case. Desert-dwelling elephants were once more widespread in Africa than they are at present; they are currently found only in Namibia and Mali. They tend to migrate from one waterhole to another following traditional routes which depend on the seasonal availability of food and water. They face being threatened by poaching and from changes in land use by humans.
