The ant  - called  Colobopsis explodens - as aptly named because when it is threatened, it explodes in an act of self-sacrifice, and releases a toxic goo that also kills the attacker.  They are found all over southeast Asia, including Borneo, where the study, led by Alice Laciny from the Natural History Museum in Vienna, Austria, took place. These ants live in the canopy of the rain forest where they are often as high up in the trees as 50 to 60 metres. There are 15 known species in this group that have this ability to explode.
