  1. Species classified as 'extinct in the wild' have only avoided extinction due to direct human involvement, often in the form of artificial habitats. In captivity, such species may even thrive. For example, red-tailed black sharks from Thailand can no longer be found in their natural habitat; however, they're exported annually in the tens of thousands to aquariums around the world [source: International Union for Conservation of Nature and Natural Resources].
