What are the threatened species? Give example any two such species.

Threatened species is the one which is liable to become extinct if not allowed to realise its full biotic potential by providing protection from the exotic species. In other words, those species whose population has been greatly reduced or whose natural habitats have been disturbed due to which these are near the extinction and may become extinct if the causative factors continue, are grouped under the category of threatened species.

Examples: Giant panda and Monarch butterfly.
