These types of dies too many males.

Two species of marsupial mice, opened in 2013, may soon become extinct due to excessive sexual activity. So mule-twilight and silver marsupial mouse was included in the list of endangered species. It is reported by the Chronicle.info with reference to eizvestia.
These types of mice are distinguished by their unusual reproductive strategy, known as the suicidal mating. Reaching puberty the body of the males of this species ceased to produce sperm. So the males for a short period need to fertilize as many females. The mating season of these marsupial mice lasts a few weeks. The sexual act in animals can last up to 14 hours and often ends in death from exhaustion, seizures or multiorgan failure. This leads to annual mass extinction of the males of this species.
“While no official plans for restoration of the species was not identified to help the tiny marsupials, or to preserve their habitats under threat. However, their introduction in the official list of endangered species can contribute to raising awareness about the plight of the species, and could provide an important basis for future efforts to legitimize their protection, ” said one of the researchers who discovered the species, Andrew Baker.
