"The breeding period is basically two to three weeks of speed-mating, with testosterone-fueled males coupling with as many females as possible, for up to 14 hours at a time," researcher Andrew Baker said in a statement Monday.

Geckos need to be separated after mating because the male will keep chasing after the female and often is so focused on continuing to mount her he starves to death.
