Termite nasute illustration (since reclassified as Nasutitermes corniger)
The fontanellar gun is a termite defense mechanism in the form of a horn-like frontal projection (nasus) on the head of the soldier caste which is capable of expelling chemical weaponry at a distance, a trait exclusive to the subfamily Nasutitermitinae. It is primarily used to ward off predators such as ants.[1][2][3]
