Yes. Marsupials are characterised by their periods of development inside the mother's body. They are born tiny and undeveloped, hairless and blind, and must make their way to the mother's pouch before they can continue their development. They spend much longer in the pouch than in the mother's body.
You can say a lot about the size of the animal and the length of development inside the mothers body. The bigger the animal inside the body the bigger it will be on the outside.
The Indian and African elephant each have long gestation periods. Elephants gestate for 23 to 24 months before being born.

Baby marsupials develop first in their mother's uterus. Inside the uterus is a yolk sac through which nutrients are given to the baby and through which wastes are released from the baby. After a few weeks (a much shorter gestation period than that of placental mammals), the baby has become more developed and is delivered.
Californium hasn't "periods" inside.
The mothers body temperature.
The differences are that placental have embryos that develop inside the mother body. The embryo grows in the placenta, which attaches the embryo to the uterus. The placenta carry's food and water to the mothers blood and carries waste from the embryo. A female monotreme lays eggs then uses energy to keep the eggs warm. She feeds them milk when they hatch. Of course, monotremes do not have nipples, so the babies lick the milk from the skin and hair around their mothers mammary glands. Finally, marsupials give birth to live young. Until big enough, marsupial babies or newborns are carried in a mothers pouch for several months.
