Pasha van Bijlert: It's not just limited to those animals—horses, gazelles, gnus—turns out that actually most animals don't tend to walk super fast.

Pasha van Bijlert：不仅限于那些动物——马、瞪羚、牛羚——事实证明，实际上大多数动物不会走得太快。

The gnus, antelopes and other grazing animals of east Africa do this, wandering around the famous Serengeti Plain to where the grass is greenest.

东非的牛羚、羚羊和其他食草动物就是这样做的，它们绕着著名的塞伦盖蒂平原游荡到草最绿的地方。
