live fast die young. The males mature about 6 weeks the females about 8 weeks. As breeders their fertility drops off at about a year old, the females generally live only about 2 years but the odd male makes it to the grand old age of 5. Not often, though. They are used as lab animals quite a lot on account of the quick generation time, NASA actually took eggs up to MIR and managed to hatch a few in zero-G!
