I saw this about 15 years ago. I loved it. Some how the video got away from me and I have been seeking it ever since. Yes, it was explicit but very informative. I even watched it with my teenage daughter and my nieces. I really enjoyed it, watched it with quite a few of my friends who enjoyed it as much. I really wish I could get my hands on a copy of the video again. The part about the kangaroo was probably the most fascinating for me. I was really intrigued with the fact that the snail was neither mail nor female. I also really enjoyed the bird that danced across the water. I can't remember the name of those birds but the dance was good. The monkeys were just plain funny. It was great the way the photographers captured the mating, births, and raising of the animals. The slow motions shots sped up to show how the spawning of fish actually took place was great. I was simply astounded by the elephant and the hippo (or rhino). I don't remember which it was but it was the one that was shown at the zoo. Is it possible that the video will ever be available for purchase again?
