Leeches are creatures that live near waters, and they usually inhabit moist environments such as swamps, paddy fields, rivers, and reservoirs. These places are often rich in water, vegetation, and organic matter, providing ample food and habitat for leeches.
Globally, leeches are mainly found in some parts of Asia, Africa and South America. In China, leeches are mainly found in the Yangtze River basin and southern regions, such as Zhejiang, Jiangsu, Anhui, Hunan and Hubei provinces. In addition, leeches are also common creatures in countries such as India, Bangladesh, Thailand, and Vietnam.
In the Americas, leeches are mainly found in countries such as Brazil, Argentina and Venezuela in the south. In the African region, leeches are mainly found in rivers and lakes in countries such as Nigeria, Ghana and Uganda.
In addition to these areas, the distribution of leeches may also exist in other areas, but they may be relatively small in number due to climatic, environmental, and other factors.
Leeches have a wide range, but their numbers can vary in different regions. In some areas, leech populations may decrease or disappear due to factors such as environmental pollution, ecological damage, and human disturbance. Therefore, the protection and restoration of these ecological environments is very important to maintain the ecological balance and protect biodiversity.
