Jaws!

I recently went on a walk in a forest in Western Kenya and stumbled into these remarkable beasts. Ants may be tiny, but they swarm in large armies and are also armed with some impressive weapons in the form of ‘jaws’ (mandibles) that can inflict a lot of damage quickly…

Among the most impressive jaws among the Kenyan ants are no doubt those belonging to the dreaded Siafu, or Safari Ants, who swarm through forests and similar habitats feasting on anything and everything they can subdue…

Here are some close-ups of the ‘soldier’ ants jaws who guard the highways that the ants run along through the forest..

Remember all these ‘soldiers’, and in fact all of the ants in the swarm are all females, all sisters and all sterile! And they are also all blind – none of the worker Siafu have eyes!

Foraging nearby were some other interesting ants with impressive jaws too. These were Trapjaw ants who hunt alone, unlike the Siafu. They walk around with their jaws held wide open, and then snap them shut when they meet a suitable prey item. The shutting of their jaws is one of the fastest movements in nature – close to the speed of sound!
