They produce up to 2 offspring but don't produce to many in a whole life time
Females will usually have one surviving cub every 2-3 years.
Each panda can only die once.
Koalas produce a single offspring, once a year. On very rare occasions, they may produce twins.
A panda has 42 chromosomes, 4 less than humans do. Other bears often have 74 chromosomes. The panda's chromosomes are often similar to 2 chromosomes of other bears fused together, which would link them to each other having a common ancestor.
A tiger can produce on average 2-6 cubs in a litter.
Offspring of true-breeding parents are called F2 generation. This is often seen in hybrid breeding programs when they are working to produce a certain trait.
The Giant Panda adult doesn't have many predators. Man, along with most of his activities are harmful to the adult Giant Panda in some fashion or another. But the most risk occurs when the mother leaves the helpless cubs, and young alone to feed, or the young first begin to explore their environment. Leopards, and Wild dogs are the most likely to attack them in those circumstances. Even though the Giant Panda have excellent hearing, and while on the alert will often hear the stealthy approach of predators, and defend their young using intimidation. They are also excellent climbers, and will hide in trees while danger passes below, and agile swimmers using water to take refuge. The Giant Panda does not hibernate, and will even sleep in the trees especially when young. The combined abilities, help the Giant Panda avoid many predators.

The Giant Panda has a thick coat that protects the animal from the extreme cold and heat that they often face in their remote China environment.
Eagles mostly nest once a year in late winter to early spring. The normal number of eaglets in the nest is two.
The Giant Panda population was thought to be about 1,600-2,000. But new DNA survey techniques have helped locate and identify where the population numbers of Giant Pandas in the wild had been underestimated. The new reports indicated there were 2,000 to 2,500 Giant Pandas living in the wild. The Giant Panda is listed by the International Union for Conservation of Nature, "IUCN" Red list as "endangered" with a population trend "decreasing". For more details, please see sites listed below.between 2000 and 3000 according to 2006 estimates.
Humans are trying to help the giant panda. There are many, many conservation projects out there maintained for the sole purpose of breeding and attempting to save giant pandas. Unfortunately, habitat loss is still a major threat to giant pandas. Another obstacle is the fact that giant pandas have a low conception rate and a low birth rate in the wild and in captivity. In captivity, it is extremely hard to know if a female is actually pregnant as female giant pandas often go through pseudo (false) pregnancies in which they exhibit all the same signs they would if they were actually pregnant. It isn't until the hormone levels of the panda decrease and a birth does not happen that keepers know the panda has experienced a pseudo pregnancy.
Giant pandas signify aggression by lowering their heads and staring at their opponents. The giant panda is a generally a passive animal and not initiate to attack man or other animals. Giant pandas, however can become violent when provoked or surprised. Generally when hearing abnormal sounds the giant panda will escape the area immediately or they will climb the nearest tree. Should they become trapped the giant panda will cover their face with their paws often hiding its eye-patches and curl up. This gesture states that they are scared and/or angry. At close range, aggression is signalled by a swipe with a paw, or by a low-pitched growl or bark that will generally send an opponent scampering up the nearest tree.
Horses and donkeys can reproduce offspring because there they are so closely related they are scientifically classified in the same kingdom, phylum, class, order, family, and genus. Their offspring will often be infertile though.
