Fertilization- How Does it Occur?
The egg travels from the ovary into the uterus. From the uterus, it is fertilized and begins development. The fertilized egg generally doesn't stay in the uterus for long if it is the first time the female has mated. It is generally around 33 days before the neonate emerges.
In kangaroos, fertilisation is carried out internally and the development is also carried out internally after birth. The kangaroo can have three young at different stages of development- one out of the pouch but still being suckled, a newborn in the pouch and an embryo in the uterus.
Species
Young and Parental Care
The Red Kangaroo is the largest mammal native to Australia and the largest extant marsupial. This species ranges throughout western and central Australia.
The young joey stays in the pouch for 190 days before being big enough to leave the pouch for a small amount of time. By the 235th day it is ready to leave the pouch for the final time. The females stay close to their mother while the males tend to stray away and find their own territory. 30 days after the joey leaves the pouch for the last time the new joey is born and the cycle starts again.
Habitat- Where Does it Live?
The Red Kangaroo is native to Australia. Its species ranges throughout Western and Central Australia. It is found across the mainland of Australia, rather than the fertile southern and eastern regions and rainforests.
