'Exploding ant' found in Borneo
A species of ant that "explodes" and gives off a toxic, sticky liquid to fight off foes and keep its colony safe has been discovered in the jungles of Borneo island, scientists said yesterday.
The creatures, which have the scientific name Colobopsis explodens, were found by a team of researchers in the tiny state of Brunei, which inhabits a sliver of land in the north of the biodiverse island.
When threatened by other insects, worker ants can rupture the wall of their body, which leads to their death and the release of a yellow toxin from their glands that either kills or holds off enemies, according to the study published in journal ZooKeys.
The scientists said the existence of a broad grouping of "exploding" ants was already known, but they had managed to identify several specific species in the course of their research.
Alice Laciny, a scientist from Vienna Natural History Museum, said the ant "explodes" by contracting "its body until enough pressure is built up to tear the body wall, then the secretion exits with a small squirt or pop". She told AFP that such a phenomenon was "very rare in nature" and only a handful of "social" insects -- such as ants and bees -- were known to sacrifice themselves in such a fashion.
