Yes, whales are placental animals and give birth to their young, just like humans and land mammals.
Whales, dolphins, and porpoises are all mammals, and just like land mammals, these animals share many of the same characteristics.
It includes giving birth, producing milk to feed their young, being warm-blooded, and requiring oxygen to survive.
One difference between whales (marine mammals) and land animals like humans is the length of their gestation period.
In humans and other land animals, this is known as a pregnancy period, the period between conception and birth.
The average pregnancy for humans lasts 38 to 40 weeks or around ten months.
A whale’s gestation period can last anywhere from 9 to 17 months, depending on the species.
Once a baby whale is born, the mother will nurse her child for approximately three months to two years, depending on the whale species, their social structure, and how quickly the baby can hunt for food and care for itself after birth.
Nursing involves feeding the child milk the mother whale produces from her mammary glands.
The whale’s milk is thick and fat, making it easier to travel through the water without breaking up and providing the child with plenty of nutrients to help it grow into a young, healthy adult.
Even after the mother whale stops lactating, her child may continue to suckle from her nipple as a form of psychological dependency.
However, this varies on an individual basis.
During this time, the mother and her child often develop close relationships, causing the mother to care for and be protective of her child.
However, as the child ages, some whale species branch out and travel alone or within a small group of other whales.
Other species, such as the killer whale, may spend their entire lives with their family and rarely separate from their pod except to find food and mate.
Despite the name “whale, the killer whale belongs to the dolphin family. However, it is part of the toothed whale suborder.
The point at which young whales reach sexual maturity and begin reproducing also varies depending on the species.
Some whales may become sexually mature at the age of 6, while other species may not reach sexual maturity until the age of 15.
After a whale has reached sexual maturity, it may begin mating with other whales and bear offspring of its own, thus repeating the process of its parents.
Lastly, as with the length of gestation and the age when they reach sexual maturity when it comes to a whale’s lifespan, how long they will live changes drastically depending on the species and their habitat.
Certain whale species have a relatively short lifespan, only living into their 20s or 30s, while others can live for 70 years or more.
A healthy bowhead whale has an estimated lifespan of up to 200 years!
Research has shown that marine mammals living in the wild have a longer lifespan than those in marine parks.
However, this is dependent upon their environment and lifestyle.
