Watch The Hyena Lady - Wolves on the Waterline

For several years, scientist Ingrid Wiesel has been studying the brown hyenas that live on Namibia's inhospitable coastal strip, which has given rise to her nickname "Hyena Lady". These hyenas are a rare breed that hunt for their food rather than live on carrion, as its fellow landbound relatives. But with hardly any freshwater available, the hyenas have developed clever methods of survival.

The Hyena Lady - Wolves on the Waterline is a 2003 documentary with a runtime of 48 hours.
