Gray wolves in the wild reach sexual maturity at approximately 2 years of age, and usually have one partner for life. The mating season is in late winter, when the female is in estrus, better known as being "in heat," for about one month. During this time, her and her partner will mate for the most part of this month to ensure that conception occurs. When a female does become pregnant, she will most likely return to her previous birthing den, where she will stay for the majority of the pregnancy. The pregnancy, or gestation period, of a Gray wolf usually lasts any where from 9-11 weeks, an average sized litter being 5-6 pups. However, a wolf may have as many as 11 or more pups in a litter depending on factors such as food abundance.
The gestation period for raccoons is 63-65 days.

Mother swordfish do not carry their young in a traditional sense, as they are ovoviviparous. This means that the eggs develop inside the female, and she gives birth to live young. The gestation period can vary, but it typically lasts around 4 to 5 months before the female releases her offspring into the ocean.
They take about 60 days to develop inside the mother snake, before she lays them.

The female humpback whale carries her calf for about 11 to 12 months before giving birth. After calving, the mother and calf often remain together for several months, during which the mother nurses and protects her young. This bonding period is crucial for the calf's development and survival.
It should be passed within a half hour of the birth of the lamb.
