Protopithecus (SciiFii)

The giant howler monkey (Protopithecus brasiliensis), also known as the robust howler monkey, is a species of New World monkey that originally lived during the Pleistocene in what is now the Toca da Boa Vista cave of Brazil, as well as other locales in the country, and was once extinct, but has since been brought back from extinction by SciiFii and reintroduced throughout the modern rainforests to help boost biodiversity. At a weight of 22.6 kilograms (50 lb), it is the largest known natural New World monkey to exist. With slightly longer arms than legs, the giant howler monkey resembles spider monkeys, but its limbs are nearly twice as thick. Its head is more similar to a howler monkey's, which has a lower jaw that juts forward to accommodate an apple-size vocal sac, and like howler monkeys, the giant howler monkey is able to howl in a similar manner. Although the giant howler monkey is primarily arboreal like its relatives, the giant howler monkey is known to occasionally travel and forage on the ground, similarly to the great apes. As a large and slow-moving monkey, the giant howler monkey is primarily a folivore which feeds mainly on top canopy leaves, together with fruit, buds, flowers, and nuts. The giant howler monkeys need to be careful not to eat too many leaves of certain species in one sitting, as some contain toxins that can poison them. Giant howler monkeys are also known to occasionally raid birds' nests and chicken coops and consume the eggs. Like howler monkeys of most species, the giant howler monkeys live in groups of six to 15 animals, with one to three adult males and multiple females. The conservation status of the giant howler monkey is Least Concern due to successful conservation efforts and the giant howler monkey's wide natural range.
