Elephants Are Terrified By Ants [Science]

The legend is that a mouse can freak out elephants, but in actual fact that their worst enemy is far smaller: Ants. Elephants get terrified of ants. That’s what Jacob Goheen and Todd Palmer have discovered in Africa’s sub-Saharian savanna.

Goheen and Palmer observed that, during an exceedingly dry year, most trees in were obliterated by hungry elephant herds. Only a single species of tree stood up, untouched: The Acacia drepanolobium, often known as the whistling-thorn tree or ant tree.

These acacias are a refuge for ants. They feed them with a sweet substance and, in exchange, the ants will attack the elephants whenever they get near it, invading their trunks and biting them badly. The scientists tested this by feeding the plant to the animals with and without ants, in addition as other species with and without ants. The elephants didn’t touch any of vegetation with ants within them.

After that, they altered ant population in the wild trees. An identical trees, without ants, got badly damaged by elephants. Their conclusion is that ants, the tiniest of animals on the African savanna, trump the most important animal in those fields. [ Current Biology ]
