A type of pouched mammal break down in drove during mating season , but the diminutive mammals currently face a much not bad terror to their survival : humans .
Two species ofAntechinus — a genus of shrew - similar animals known for marathon union sessions that leave the male crippled , spent and exit — were recently added to the Australian endangered species list , representatives of the Queensland University of Technology ( QUT ) reportedin a statement .
If mating doesn’t kill them, humans will.
In a decision effective May 11 , the Australian political science ’s Threatened Species Scientific Committee ( TSSC)declaredthe silver - headed antechinus ( Antechinus argentus ) and the black - trail dusky antechinus ( Antechinus arktos ) peril , in the first place due to hard reduced habitat and other risks brought about by human - induced mood change .

Currently , there are 15 known species of antechinus in Australia ; the silver - headed antechinus was identified in 2013 , and the dusky antechinus was identify in 2014 , according to the TSSC account . Both species are modest and carnivorous , with silver - headed Male weighing about 1.5 troy ounce ( 43 g ) on intermediate and twilit male weighing about 3.2 ounces ( 90 grams ) on average .
Antechinuses , which are only found in Australia , New Guinea and Tasmania , are known for an strange and utmost mating strategy get it on as suicidal facts of life . During reproduction season , the animals madly pair for up to 14 hours at a meter andexpire fromexhaustion , hurt and organ bankruptcy in a subject of weeks , leading to one-year mass dice - offs of antechinus male .
But the butchery ofantechinus matingisn’t why the two species are facing an uncertain future . Rather , they live high - altitude forest home ground , where these animate being face grow threats of wildfire , depredation from invasive metal money such as cat and foxes , and habitat ruffle from Bos taurus and feral pigs , the TSCC reported .
Both the atomic number 47 - steer antechinus and the dusky antechinus were found high up on mountains in southeast Australia ; they were probably driven to the misty summits by changingenvironmental precondition , Andrew Baker , one of the researchers who discovered the two metal money , and a senior reader with QUT ’s science and technology department , said in the affirmation .
" They have likely retreated there as the mood has warm , and there is now nowhere left for them to go , " he said in the affirmation .
As yet , no official recovery plans have been outline to serve the tiny marsupials or to conserve their threatened habitats , concord to the TSCC report . However , the new military position on the official endangered species listing will advance awareness about the antechinuses ' quandary , and could lay important groundwork for future efforts to legislate their protection , Baker said .
" If we take immediate action , hopefully in prison term we will see the antechinus take out from the peril list , " Baker say .
