What kinds of animals are there in Africa?

Africa is famous for the variety and quantity of its wild animals. There are more large ungulate mammals (about 90 species) and freshwater fish (more than 2,000 species) than other continents. There are about 3,000 species of fish, 238 species of amphibians, 58 species of reptiles, 589 species of birds, and 0/0/00 species of mammals.

There are at least 40,000 species of plants in Africa. The forest area accounts for 265,438+0% of the total area of Africa. Rich in mahogany, ebony, rosewood, Keba, ebony, Cinnamomum camphora, Castanopsis fargesii, walnut, lacquer wood, Quercus variabilis and other economic trees. The grassland is vast, accounting for 27% of Africa's total area, ranking first in all continents. The exploitable hydraulic resources are abundant.

There are many kinds of proven mineral resources in Africa, with large reserves. Rich in oil and natural gas; Iron, manganese, chromium, cobalt, nickel, vanadium, copper, lead, zinc, tin, phosphate and other reserves are very large; Gold and diamonds have a long reputation; The discovery of uranium veins has attracted worldwide attention. The reserves of many minerals are among the highest in the world.

Extended data:

I. Geographical environment

Africa is located in the southwest of the old hemisphere, spanning the north and south of the equator, and some parts of the northwest extend to the western hemisphere. It borders the Indian Ocean in the east, the Atlantic Ocean in the west, Europe across the Mediterranean Sea and the Strait of Gibraltar in the north, and Asia in the northeast corner with the narrow Red Sea and Suez Canal.

The mainland is east to Cape Hafeng (5124' E, 0/0 27' N), south to Cape Gullers (20 02' E, 34 51'N), and west to Cape Verde (0/7 30 W).

About 30.2 million square kilometers (including nearby islands). It accounts for about 20.2% of the world's total land area, and is the second largest continent in the world after Asia.

Secondly, hydrology.

The outflow area of Africa accounts for about 68.2% of the whole continent. The outflow systems of the Atlantic Ocean are mostly rivers with a long history, including Nile, Congo, Niger, senegal river, volta river and Orange. With a total length of 66,765,438+0 km, the Nile is the longest river in the world.

The basin area and flow of Congo River are second only to Amazon River, ranking second in the world. The outflow system of Indian Ocean includes Zambezi River, limpopo river River, Juba River, short rivers on the east coast of Africa and rivers on Madagascar Island.

Africa's internal water system and no-flow zone covers an area of 9.58 million square kilometers, accounting for about 3 1.8% of the total area of the whole continent. Among them, only Lake Chad basin has a perfect water system. Okavango River basin and Sahara desert are very dry, and there are many intermittent rivers and many dry valleys in the desert.

The inflow area also includes the lake area of the Great Rift Valley in East Africa, and rivers flow into the lake from the surrounding highlands. The lake area has abundant rainfall and dense river network, which is different from other arid inflow areas. African lakes are concentrated in the East African Plateau, and a few are scattered in inland basins.

Plateau lakes are mostly fault lakes with long and narrow water depth, which are arranged in the Great Rift Valley of East Africa in a beaded shape, among which Lake Victoria is the largest lake in Africa and the second largest freshwater lake in the world.

Lake Tanganyika is the second deepest lake in the world. Lake Tana, located in the Ethiopian Plateau, is the highest lake in Africa, with an altitude of1830m. Lake Chad is the largest lake in the inland basin, and its area often changes.
