How many kinds of animals are there in the zoo?

The types and numbers of animals collected by different zoos vary greatly, depending on the zoo's size, financial situation, geographical location, environmental conditions and other factors. The animal species collected in zoos around the world can be divided into several categories such as mammals, birds, reptiles, amphibians and invertebrates.

According to statistics, there are more than 7,000 species of mammals and more than 10,000 species of birds in the world, and the animal species displayed in zoos usually account for a small part of the total. For example, the San Diego Zoo in the United States has a collection of more than 3,700 individual animals, including more than 400 species of mammals, more than 800 species of birds, and more than 200 species of reptiles. In China's Beijing Zoo, it has a collection of nearly 600 species of animals, including more than 300 species of mammals, more than 150 species of birds, more than 50 species of reptiles, and nearly 30 species of amphibians.

In summary, the types and numbers of animals collected in zoos vary by region, time, and other factors, but in any case, zoos should ensure that the animals in their collections receive appropriate life and health care.
