Wild boar is a nearby relative of domestic pig. There are four category of wild boar that are similar in size and appearance, but differ in colour (which depends on the kind of habitat). Native populations of wild boars can be found in Europe, Africa and Asia (India, Japan, Indonesia, and the Far East). Wild boars can survive in different types of habitat: taiga, grasslands, rainforests, tropical but they prefer life in deciduous forests. Wild boars are threatened by habitat loss and by commercial hunt. Luckily, wild populations are still constant and they are not listed as rare species.
