Here's a breakdown of the reproductive process:
* Mating: Giant pandas only mate for a very short window of time, typically during the spring (April-May).
* Gestation: The gestation period is long, with the fertilized egg remaining in a state of delayed implantation for about 2-3 months. This means the embryo doesn't immediately attach to the uterine wall.
* Birth: Usually, only one cub is born, but twins are possible. Cubs are born blind, deaf, and very small, weighing only about 100-150 grams.
* Care: Panda mothers are extremely devoted to their cubs, caring for them for around 18 months. They nurse, groom, and protect their young.
The long gestation period, along with other factors such as limited mating opportunities and low cub survival rates, contributes to the giant panda's endangered status.
