Myrmecia piliventris is also known as the
golden-tailed bull ant, it has been found mostly along the East coast of Australia from
Brisbane to Adelaide, but is also mentionned from Perth and Wynyard in Tasmania. This ant is a mystery: We don’t know why they
have a golden abdomen, and fact extremely unusual for a social insect, they only have
two pairs of chromosomes! The genus Myrmecia actually has an incredibly
diverse number of chromosomes among its species. And Myrmecia piliventris doesn’t even have
the lowest count since a colony of Myrmecia pilosula was found to have only one pair. The record in this genus belongs to the ant
Myrmecia brevinoda with 42 pairs of chromosomes Surprisingly enough, scientists have no idea
why they have such a diversity of chromosomes counts nor Whether they evolved from a very
low or very high amount. I hope you will enjoy the rest of this video, please don’t forget to subscribe!
