Most if not all mammals can swim including elephants , even if they choose not to, and some can override their instincts not to as some higher functioning mammals do. Obviously this makes it more difficult to provide a definite answer for many species. . It is a fallacy that any mammal has a gestation period of 8 days.
And the chicken egg if fertilized can have an incubation period of 21 days at which time a baby chick will hatch out.

The average gestation period of an elephant is about 640 to 660 days, or roughly 95 weeks. However, in reality, pregnancy length may differ. Other animals that have gestation periods closest to that of humans are: dolphins - 276 days, chimpanzee - 237 days and cattle - 280 days. Non-mammalian species that display gestation carry around developed, rather than developing fetuses in their body. Thus, mice have evolved very short gestation periods.
Mammals usually have 7 neck vertebrae. The eggs take about 12 days to hatch. May be the little known but surprising fact about dolphins is their long pregnancy period. Even a newborn elephant would weigh between 90 and 115 kg. In general, the larger the animal, the longer the gestation period. Blue whales, which are the largest animals in the history of the Earth, do not carry their young for the most amount of time; they are outstripped by relatively 'smaller' animals such as tapirs, camels, and elephants.
Another feather in the cap for the blue whale is that it is also the loudest animal on Earth. An all-breed average is about 283 days, with the breed-specific averages ranging from approximately 279-292 days. Among the diverse group of whales, the sperm whales have longest pregnancy period — about 16 months. But the starting point of this magical relation is the gestation period. The shortest gestation period known in mammals is approximately 12 days.
Monotremes are mammals; specifically, they are egg-laying mammals. Although elephants usually only carry one baby at a time, one to two percent of elephant births produce twins. The defining characteristic of a mammal is that it suckles its young on mothers' milk, and monotremes certainly do this. Only one whale calf born at a time. What this means is that female elephants continue to remain pregnant for nearly 2 full years.
It becomes mature at the age of three. As thumb rule, gestation periods depend on the animal's size, but this characterization is not always true. Check out the list of animals with longest gestation period. Ross is a former art director of the Los Angeles Times, Associated Press and United Press International. The largest mammal on land is the African elephant. The maturity comes at the age of two. The Short Nosed Bandicoot Only Has 12 Days Of Being Pregnant! A single baby giraffe or calf would be born after that.
Theria These mammals carry their offspring in the womb for a certain period before it is born. Elephants have the longest gestation period of all mammals. But it can be quite long. There are 30 000 000 insect species, some not yet discovered. In mammals, the gestation period is different for different animals. Surprisingly, the calf could swim within an hour after the birth. Anemia is caused by low iron and is common in pregnancy because the baby is using a lot of red blood cells to grow.
Elephants have the longest gestation period of all mammals, carrying their young for nearly two years before giving birth. In general it appears to be very short in small mammals, some shrews and mice are only a few days while increasing in length as the mammal increases in size. They are also called monotremes. There are about 509 … 6 mammal species Check out Walker's Encyclopedia of Mammals. For most animals, the gestation period is much shorter than the time between laying the eggs and the eggs hatching: for example, a chicken egg has a gestation period of one day, but the eggs do not hatch until 24 days after being laid.
So writing the whole list would take a while. Female zebras can breed by the age of three. Other Mammals - Vaughn's Summaries Pregnancy Length Gestation Periods Chart by - Here is a pregnancy period comparison chart of human babys, selected pets and other mammals. Not all vertebrates are mammals, though all mammals are vertebrates. Using the Scientific Name of course. Gestation period refers to the time period required for the development of a fetus. He specializes in explanatory graphics that deal with science topics.
