“Very small forest-dwelling wallabies are known as pademelons (genus Thylogale) and dorcopsises (genera Dorcopsis and Dorcopsulus). The name wallaby comes from the Eora Aboriginal tribe who were the original inhabitants of the Sydney area. Wallabies are herbivores whose diet consists of a wide range of grasses, vegetables, leaves, and other types of foliage”. – Wikipedia

“The Rothschild Giraffe (Giraffa camelopardalis rothschildi) is among the most endangered giraffe subspecies with only a few hundred members in the wild. It is named after the famous family of the Tring Museum's founder, Lord Walter Rothschild, and is also known as the Baringo Giraffe, after the Lake Baringo area of Kenya, or as the Ugandan Giraffe. All of those that are living in the wild are in protected areas in Kenya and Uganda. (Recently it has been proposed that the Rothschild Giraffe is actually a separate species from other giraffes and not a giraffe subspecies).” – Wikipedia
