 In the heat of the day, hunters can afford to slow down and rest in the shade. It’s one of the advantages of a high-protein diet. 

 

Llamas originated here in North America are the regular visitors to the spring. The strange-looking tapir is common too. And there’s another animal that’s even more bizarre, a glyptodont. 

 

This lumbering¹ vegetarian² is no threat to the llamas, but it does arouse their curiosity. 

 

The glyptodont is short-sighted and wary³, but it has little to fear from llamas. They are easily warned off and soon head back towards the spring. 

 

But as the day cools down, another scent⁴ is in the air, alerting the tapir’s ultra-sensitive nose to danger. The llamas pick up the signals too. 

 

It’s the jaguar⁵, back on the prowl.
