Gestation.
internal. They develop inside the womb
Placental mammals.
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.
no thay are fish Only mammals have nipples
Most embryos of mammals develop inside the mother's uterus, attaching to the uterine wall where they receive nutrients and oxygen through the mother's blood supply. This allows for protection and support during development until the offspring is ready for birth.
yes of course the baby of mammals develop in eggs inside mother. Here the fertilization will be internal. There are some egg laying mammals also......such as platypus and Pygmy shrew.
Whales are ovoviviparous because they are mammals, because of this their eggs develop inside of their bodies and they give birth to live young.
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.
Most mammals are placental mammals: they develop in a placenta before birth. Marsupials also develop in a placenta, but they are delivered much earlier and the placenta is less developed. Monotremes develop within an egg, which is kept inside the mother for some time before it is laid. It hatches several days later.
Mostly, yes. With the exception of monotremes (egg-laying mammals which include the platypus and the echidna), mammals are born live, not from eggs. The defining characteristic of mammals is that they all feed their young on mothers' milk.
No, the majority of animal embryos develop outside the mother's body. This includes animals such as birds, reptiles, and most fish. Embryos that develop inside the mother's body are found in live-bearing mammals as well as some fish and sharks.
They do have an anal opening, called a vent.
