 Fifteen new species of "exploding ants" – including a whole new science – were discovered in Southeast Asia, Gizmodo reported, citing the findings of a study published Thursday in the science journal ZooKeys.
"Colobopsis explodens" are able to rupture their abdominal walls to secrete a sticky toxic liquid that kills predators and themselves.
Scientists have been investigating other types of "exploding ants" for decades, but a lack of new evidence since 1935 has led to a multi-disciplinary team of Viennese scientists exploring Southeast Asia.
The researchers observed that the ants displayed a range of behaviors that served the interests of their colonies rather than themselves. The drive to perpetuate their own genes, like most creatures, was secondary to the needs of the colony.
The ants were seen transporting bridges or liferafts with their bodies, and other wounded ants were taking a few examples.
The self-sacrifice was most often performed among so-called small workers, the detailed investigation. In some cases, the ants blew themselves when the scientists came too close.
The ants feed on algae, most of them, fungi, dead insects, fruits and fish,
