Least Concern is an animal classification established by the International Union for the Conservation. Species classified as “least concern” are not a focus of conservationists because they don’t appear to be facing any imminent threats. The IUCN will not add species to the Least Concern list unless scientists have evaluated them. Additionally, LC animals are not red-listed, but they still have a category.

Currently, 14,033 species of animals are on the Least Concern list.
