Lion

Africa holds perhaps 20,000 to 25,000 wild lions, down from a couple hundred thousand a century ago, and Etosha is one of the strongholds where you can still watch a whole pride operate. Namibia also keeps a wilder secret: a small population of desert-adapted lions that patrol the Skeleton Coast, hunting seals where the dunes meet the Atlantic, something recorded almost nowhere else on Earth. A male can pass 200 kilograms, and a pride is really a matriarchy: related females who hunt together, raise cubs together, and hold the territory while males come and go on shorter, harder careers. Most of a lion's day, up to 20 hours of it, is spent doing magnificently little.
