Tasmanian Wolf: Thylacinidae

Not much is known about the behavior and reproduction of Tasmanian wolves. These animals were bred in captivity only once, although females with live young in their pouches were caught and kept in zoos. Scientists think that reproduction was timed so that young Tasmanian wolves left their mothers during the warmer months, as this was when food was more available, giving the young a better chance of survival. They believe that pregnancy lasted only one month. The poorly developed young then moved into the mother's pouch where they nursed until they were developed enough to survive on their own and eat solid food. Beyond this, little is known about their reproductive systems, how long the young would stay in their mother's pouch, or even how many young were in an average litter.
