It measures approximately 10 mm for the workers, 12 mm for the Gyne.
Its mandibles are able to open up to 180 °, and is impressive, with an organic mechanism they can close a blow if it titillates the small hairs which lies all along.
To give you an idea, the speed of closure of the jaw than 130Km / h is the absolute record in the animal kingdom.
Once closed, the same mechanism completely blocks the jaw to make it impossible to open even forcing.
They also use their jaws to eject a blow and sent waltzing away intruders like a catapult.
Not for nothing it deserves its nickname of "Trap-jaw".
As one might expect, so it is primarily a hunter equipped for war.
Another feature, not least, they are not very fortiche to mount the windows ^^.
And this is the formicarium I have build for it:
