Kangaroos are the largest Marsupials alive today. They currently are native to the continent of Austrailia. There are four different sub-kinds in the kangaroo baramin: the Western Gray Kangaroo, the Eastern Gray Kangaroo, the Red Kangaroo, and the Antilopine Kangaroo.
Kangaroos have large ears on top of their small heads, a long snout, and short arms with clawed fingers. Their legs are strong and powerful, designed by God for leaping. Their feet have four toes at the end of elongated metatarsi that they rest on when standing. They also have a powerful, thick tail that is used as support when standing, a third-leg when walking slowly, and for counterbalance while leaping. Like all Marsupials, female kangaroos have a pouch on their stomachs in which they carry their young.
Kangaroos are herbivores, eating grass, roots, and shrubs. They have a chambered stomach similar to sheep and cattle. They are able to regurgitate their food, chew it again as cud, and then swallow it for digestion.
Kangaroos travel in mobs of about ten or more males and females. The leader of the mob, called a "boomer", is a male determined by age and size. The boomer has access to females in his mob for mating and will wander around the mob intimidating any other males who try to mate with his harem.
Male kangaroos will go around the mob checking the females’ cloaca. Many times, males are rejected by the females because of size if they are small. In other cases, if a larger male is checking a female out, she may just move away. Sometimes, when a male is checking out a female, the female will urinate for the male, who will sniff the urine. Some studies show that this ritual is for the male to see if the female kangaroo is receptive to him or not.
If the female is responsive to the male, she raises her tail and the male will follow her. Sometimes the kangaroos will scratch each other’s tails or the male will give the female a back rub before mating. When the female is ready to mate she will arch her tail.
Female kangaroos usually only have one baby kangaroo (called a "joey") at a time. The newborn joey weigh as little as .03 ounces when first born, after which it crawls into its mothers pouch where it will nurse, grow, and develop. They spend a lot of time in their mothers pouch developing. The Red Kangaroo joey will stay in their mothers pouch for about eight months and Gray Kangaroo joeys stay in there for about a year.
Like all modern animals, modern kangaroos originated in the Middle East and are the descendants of the two founding members of the modern kangaroo baramin that were taken aboard Noah's Ark prior to the Great Flood. It has not yet been determined whether kangaroos form a holobarmin with the wallaby, tree-kangaroo, wallaroo, pademelon and quokka, or if all these species are in fact apobaraminic or polybaraminic.
After the Flood, kangaroos bred from the Ark passengers migrated to Australia. There is debate whether this migration happened over land -- as Australia was still for a time connected to the Middle East before the supercontinent of Pangea broke apart -- or if they rafted on mats of vegetation torn up by the receding flood waters.
