From The Daily Mail UK:

The superlions marooned on an island

Marooned on an island, this group of lions should have died out. Instead, in an evolutionary twist, they’ve learned to swim and become strong enough to tackle their only prey… giant buffalo

Fearless, ferocious and mightier than the world has ever seen, this is the new breed of super-lion.

Only one species of prey holds its attention: the buffalo — and in order to bring its powerful foe to the ground, it will take to deep water, use sophisticated hunting techniques and then silence the gigantic beast with a single swipe of a savage paw.

In a remote corner of Africa, an extraordinary evolutionary tale is unfolding, uncovered by the actor Jeremy Irons and an award-winning documentary team. A new film, Relentless Enemies, will tell the story of the emergence of a distinct subspecies of big cat on a tiny and isolated island in the Duba Plains of Botswana’s Okavango Delta.
