Scientists have made one of the largest animal discoveries of the century - a new species of tapir. The mammal is new to science but was known by local indigenous tribes, and is one of the biggest animals on the South American continent - despite being the smallest of the living tapir species. Tapirus kabomani or the Kobomani tapir is the first tapir to be discovered since 1865, and is part of the mammal family that includes rhinos and horses.
