Do marsupials and placental mammals both develop their young at least partly within their bodies in a uterus?
Yes, both marsupials and placental mammals develop their young partly within their bodies in a uterus. However, the key difference lies in the duration and nature of this development. In placental mammals, the young are nourished through a complex placenta for a longer gestational period, while marsupials give birth to relatively undeveloped young that continue to grow and develop in a pouch after birth.
Where in the mammals' body do the young ones develop?
Dolphins are mammals; their reproductive process is essentially the same as that of human beings, even if they happen to be in the water at the time. The zygote of a dolphin develops in the uterus of the mother dolphin.
Are porcupines placental?
Yes, porcupines are placental mammals. They belong to the order Rodentia and give birth to live young that develop within the mother's uterus, receiving nourishment through a placenta. This reproductive strategy is characteristic of placental mammals, distinguishing them from other groups like marsupials and monotremes.
Are tigers a placental mammal?
Yes, tigers are placental mammals. They belong to the order Carnivora and are part of the family Felidae. As placental mammals, tigers give birth to live young that develop inside the mother's uterus, receiving nutrients through a placenta during gestation. This reproductive strategy is characteristic of most mammals in this group.
Do lions have amniotic or non amniotic eggs?
Lions do not lay eggs; they are mammals, and like all mammals, they give birth to live young. Mammals have amniotic eggs in their evolutionary history, but they do not produce eggs in the same way that reptiles or birds do. Instead, lion embryos develop within the mother's uterus, surrounded by amniotic fluid.
Are rhinos marsupials?
No. Rhinos are placental mammals meaning they give birth to relatively well developed young. Marsupials give birth to underdeveloped young that are nourished and develop in a pouch.
What is the method of birth of mammals?
Mammals give birth to live young
Why does mammals gave birth to their young?
Mammals give birth to their young for purposes of procreation. This is what ensures that the life cycle of the mammals is continued.
During what time do young placental mammals develop inside the uterus?
The carrying of live young inside a female animal that gives live birth is called gestation. The length of the time spent in the gestation of one baby or one litter of young is called the gestation period. The time that a baby spends inside its mother (if its mother gives live birth) is called the gestational age.
Why don't whales lay eggs?
Whales are ovoviviparous because they are mammals, because of this their eggs develop inside of their bodies and they give birth to live young.
What are Mammals that give birth to young at very early stage of development called?
These are marsupials, most of which then carry their young in a pouch while the joeys continue to develop.
How do the bones in the young of mammals develop?
chicken
