MACROPOD REPRODUCTION AND THE DEVELOPMENT OF JOEY IN THE POUCH
MACROPOD (KANGAROO AND WALLABY) REPRODUCTION IS TRULY FASCINATING
AT THE END OF THE PREGNANCY THE EXPECTANT MOTHER TAKES UP A SITTING POSITION AND GROOMS HER POUCH
BUT THE AMAZING STUFF DOESN’T STOP THERE!
The following pictures are sequenced pictures of a joey developing in the pouch. Thank you to Rex Paperd and his ultra-tame wallaroo for providing them.
You can see how the question “How old is the joey?” does not have a simple answer. To say that a baby that has just come out of the pouch is eight months old is misleading to most people because they don’t understand the process. An eight month old placental mammal like a dog or a cat would be approaching sexual maturity at that age. But an eight month old joey (counting from it’s birth) is only the equivalent of a newborn placental. To avoid this confusion I usually answer “She’s been out of the pouch for a few weeks.”
