New Species of Marsupials Have Suicidal Sex Habits
20 February 2014 1:45 pm
Researchers have discovered three new species of Antechinus, rodentlike marsupials, with suicidal sex habits, The Guardian reports. The critters are notorious for the males’ tendency to keel over after an intense 2-week mating season that includes multiple rounds with females that can last up to 14 hours. The sexual hyperactivity ensures that males pass their genes on to the next generation, but it also irreversibly damages their muscles and destroys their immune system, which kills them after mating season ends. The species discovery is detailed this week in Zootaxa.
