Do mammals have internal or external development?
internal. They develop inside the womb
Why do offspring develop inside their mother?
Placental mammals.
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.
Do sharks have nipples?
no thay are fish Only mammals have nipples
What do most embryos develop inside the mother?
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.
Do mammal babies develop in eggs?
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.
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.
Do a giraffe develop internal or external?
Giraffes develop internally, like most mammals. The embryos grow inside the mother's uterus during a gestation period of about 15 months. After birth, the young giraffe, called a calf, is relatively well-developed and stands shortly after delivery. This internal development allows for better protection and nourishment of the developing young.
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.
Where do most mammals grow before they're born?
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.
What animals develop babies inside the womb?
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.
Do the majority of animal embryos develop inside the mother?
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.
