Tammar Wallabies are widely studied due to their unique reproductive abilities and gestation. They’re polygynous breeders; in other words, a female can mate with several males, holding a joey in her pouch while another embryo remains dormant in their womb until the first joey leaves.
The young joeys are bald, blind and about the size of a jellybean when they’re born.
It takes them up to 200 days to leave the pouch. They will venture to nearby food sources, but tend to stay very close to their mothers until it’s time to venture further.
