01 Elephants.

The elephant has the longest gestation period among mammals, with a gestation period of up to 22 months. Generally speaking, the gestation period of mammals is about 10 months. For example, cows, horses, donkeys, chimpanzees, etc., which are very familiar to everyone, the gestation period of kittens and puppies is only 4 months!

The pregnancy of fin whales takes 11 months. But none of them can compare to elephants.

Elephants are the world's largest land mammal, although they are pitifully small compared to the world's largest mammal, the blue whale. An adult elephant weighs only 1 4 times the tongue of a blue whale. But on land, the elephant is definitely a giant.

Even the smaller female elephant weighs around three tons, almost twice as large as the second-largest rhinoceros. It is precisely because they are so much larger than other animals that they are almost invincible animals in their habitat.

But why haven't elephants taken over the planet? Some people joke that it is the work of the Creator, who made the elephant the longest-pregnant species of mammal, with a gestation period of up to 22 months, in order to prevent elephants from taking over the earth. As a result, elephants reproduce much less quickly than other animals, making it difficult for them to quickly develop a population advantage!

It is estimated that it takes 22 months for a mother elephant to fertilize and give birth to a calf, more than double the number of humans conceived in October. After 22 months, the mother elephant gives birth to a baby elephant weighing at least 100 kilograms! Despite the long pregnancy period of the elephant, in fact, the baby elephant is much more fragile after birth than other mammals in nature.

It is not until five or six days later that the baby elephant has the ability to walk freely, so during this time, the mother elephant must always be around the baby elephant to protect it from carnivores. In order to adapt to their surroundings, the baby elephant has to learn a lot of life skills from the mother. For example, they learn how to use their noses to grasp food.

Newborn baby elephants do not have the ability to use their noses flexibly, so they need to be taught by their mothers to become familiar with the functions of their noses.

It is a long process from birth to being able to live independently. For five years after birth, it is under the care of its mother. It is precisely because the baby elephant needs to be cared for by the mother elephant for a long time that the reproductive ability of the mother elephant is extremely low.

In addition to being 22 months pregnant, they have no way to get pregnant again within five years of caring for the baby elephants. In other words, a female elephant only produces one offspring every seven years. A female elephant does not reach sexual maturity until she is at least 10 years old, and the best breeding age for them is 25 to 45 years old, and the best breeding time is only 20 years.

So in the lifetime of a mother elephant, there can only be three or five offspring. Among these offspring, they must be able to avoid the threat of disease and predators, and even fewer will actually grow up. As a result, it is difficult for the elephant population to form a very large herd in a short period of time and affect the ecological balance.
