The event talks about the features, characters of the wild animals.
<u>Explanation:</u>
When the author describes the event in which the humans are attacked by the lions, it describes about the features, the characteristics of the animals which are wild and live in the jungle.
The author shows that the animals, to satisfy their hunger and to hunt for their prey, they can hunt down the human beings also and can eat them up also if they have a chance.
Neither, a metaphor would be like "I'm so hungry that I could probably eat an elephant," while a simile would have 'like' or 'as' to describe something.
