Frugivorous Monkeys

Agile gibbons, also known as dark-handed or black-handed gibbons, are arboreal monkeys; they are always in the trees. Agile gibbons belong to the great ape family. However, they are categorized as lesser apes because they are smaller than great apes.

Andean night monkeys are a genus Aotus, commonly known as nocturnal monkeys or the Peruvian night monkey. Species in this genus are the only truly nocturnal monkeys in the world. Andean night monkeys are not sexually dimorphic as males and females look very similar.

The Ashy black titi is a species initially described in 1823 as Callicebus cinerascens. Ashy black titi monkeys live in small families comprising a monogamous pair and their young. Adult males tend to carry their infants unless the mother is nursing.

The Atlantic titi, also known as the masked titi, inhabits the rainforests of the Atlantic coast of Brazil east of the Andes in the states of Bahia, Espírito Santo, northwest of Minas Gerais, north of Rio de Janeiro, and São Paulo. This species, found nowhere else in the world, inhabit the tropical forests of Brazil's Atlantic coast east of the Andes.

Azara's night monkeys, also known as southern night monkeys and Azara's owl monkeys, are native to the Gran Chaco region of South America, a vast area with many different ecosystems, from savannas to grasslands to dry spiny forests and gallery forests. Genetic testing has shown that the males of this species mated pairs are the fathers of the babies they care for.

The obscure Bald Uakari (Cacajao Calvus) is an acrobatic Amazonian monkey with a flaming red face uniquely adapted to periodically flooded forests. Surprising insights on its taxonomy, specialized seed-based diet, unusual social life, habitat flexibility, and urgent need to conserve diminishing flooded forest habitat across the Amazon Basin.

The Banded langur, also known as the Raffles' banded langur or banded leaf monkey, is a primate species in the Cercopithecidae family. Like other Colobin monkeys, whose young typically have lighter-colored fur than adults, Banded langur infants have white or tan fur until it darkens around 6 months.

The gray-bellied night monkey (Aotus lemurinus) is a rare nocturnal primate found in the cloud forests of Colombia and Ecuador. Recognizable by its red eyes, gray underbelly, and woolly coat, it thrives in dense canopies where it feeds on fruits, insects, and nectar. Its nocturnal habits reduce competition and help it evade predators like owls and snakes. As both seed disperser and prey, it plays a key ecological role—yet habitat loss continues to threaten its survival.

The gray-handed night monkey (Aotus griseimembra) is a small, nocturnal primate native to Colombia, Venezuela, and Panama. Known for its large owl-like eyes and gray limbs, this tree-dwelling monkey thrives in rainforest canopies and plays a vital role as a seed disperser. Monogamous and family-oriented, it relies on both parents—especially the father—for infant care. Though adaptable, habitat loss, hunting, and the pet trade threaten its survival, earning it a Vulnerable status on the IUCN Red List. Conservation efforts are crucial to preserve this unique night-dweller and its forest ecosystem.

Robinson's banded langur (Presbytis robinsoni), also known as Robinson's banded surili, is a monkey species in the Cercopithecidae family. Robinson Banded Langurs are generally shy and alert creatures, rarely leaving the comfort of the canopy.
