What is the average weight of a tauntaun and in which season do they prefer to mate? — Jesse
Tauntauns, a semi-reptilian mammal, are one of the few lifeforms living on the frozen planet of Hoth. While there are several different species of tauntaun, the one seen in the film is a giant common tauntaun. These are typically 8’2″ tall and about fifteen feet long. Their internal organs are protected by a thick layer of blubber and thick white or gray fur. While none of the sources I have on hand speculate on weight, it seems safe to assume they are well over 3,000 lbs.
Hoth does not actually have seasons, per se, but tauntauns can have up to two young at a time twice in the Hoth year. Their young are born live, and while the female tauntauns do not have mammary glands, they can provide a milky sustenance from their crops for the newborns.
You can read more about tauntauns in The Wildlife of Star Wars: A Field Guide (ISBN 9780811828697), pp. 46-9. It is possible that more of the specific information you’re looking for could be mentioned here — though I would not guarantee it.
