Although we romanticize lions as mighty kings of the jungle, their reign is in fact a tenuous one. It is challenged daily in southern Africa by vicious packs of hyenas that compete for prey. Between the two species exists an ancient feud, and it unfolds in Eternal Enemies with all the drama of the warring Capulets and Montagues. Watch as lions bring down a zebra, only to be attacked themselves by a pack of hyenas that chases them into the trees. Glowering, the big cats watch as the thieves devour their dinner. Days later the lions exact revenge, killing the hyena leader but leaving her uneaten as a warning to the rest of the clan. Other scenes in this video are equally impressive, including life inside a hyena den--which captures the sounds of lions growling outside--and a tense encounter between a snake-bitten lioness and a pack of hyenas. With its gripping story line, Eternal Enemies is a standout among animal documentaries. --Demian McLean
