Two species of marsupial namely- the tiny black-tailed dusky antechinus and the silver-headed antechinus are on the list of endangered species of Australia. The male mammals of the species reportedly die after long sex sessions. The scientists warned on Tuesday of the marsupial species to be on the verge of extinction.
The marsupial species generally live in the higher-altitude and wetter areas of Queensland. They are noted for their mating activity which is much like suicide. Their mating habit involves sex session up to fourteen hours after which the male mate loses its life.
The scientists have revealed that the other factors contributing to the death of the species are- loss of habitat, climate change, and feral pests. The researchers fear that these mouse-like species would soon tend to die off residing in a country like Australia which is known to be experiencing the “highest mammal extinction rate” in the world.
Australia has a total of fifteen antechinus species, which were initially found by Dr. Andrew Baker of the Queensland University of Technology along with his research team in South East Queensland. Baker expects that the listing of these species- the tiny black-tailed dusky antechinus and the silver-headed antechinus- in the endangered list would provide them with increased protection.
Mammalogist Andrew Baker said in a statement that the mammals of the species are extremely frantic and tend to change mates continuously and the sex sessions last for hours together making them tired. Baker told that the mating period of the species ranges for two weeks towards the end of Southern Hemisphere winter. He explained that the healthiest male mammals are seen to die instantly before the eyes after their sex sessions during their mating period.
They reportedly tend to have so much of sex and even cling on to the female mates fighting away their rivals. This is said to generate increased testosterone levels within the mammals. These increased levels stop switching off of the stress hormone. This condition damages their organs and results in the death of the animals.
Baker said that these animals are walking towards their end. Baker further added that these animals are seen to be losing their balance while walking during daytime yet seeking mates, with blood oozing out from their different body parts and hair fallen off. Dr. Baker is reportedly working towards relocating the endangered species to new locations. He would be doing this with the help of a “detection dog.” He said that in the previous year the Black-tailed Dusky Antechinus was located by a “detection dog” at the Border Ranges.
