Howler monkeys are perhaps the most folivorous of the New World monkeys. Fruits make up a relatively small portion of their diet, [30] and the type of leaves they consume (young, nutritive, digestible, often reddish in color), are best detected by a red-green signal. Field work exploring the dietary preferences of howler monkeys suggest that ...
Most modern primates, however, have evolved to be trichromats. All old world monkeys and apes are trichromats, but new world monkeys are polymorphic trichromats, meaning that males and homozygous females are dichromats while heterozygous females are trichromats (with the exceptions of howler monkeys and night monkeys, who have more and less ...
Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was recently proposed that recognises three genera within the subfamily Callicebinae; Cheracebus Byrne et al. (2016) for the species of the torquatus group (Widow titis); Callicebus Thomas, 1903, for species of the Atlantic Forest personatus group; and ...
Today, among simians, the catarrhines (Old World monkeys and apes, including humans) are routinely trichromatic—meaning that both males and females possess three opsins, sensitive to short-wave, medium-wave, and long-wave light [4] —while, conversely, only a small fraction of platyrrhine primates (New World monkeys) are trichromats.

Plecturocebus is one of three genera of titi monkeys.. Historically, these monkeys were monogeneric, being placed in a single genus: Callicebus Thomas, 1903.Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was proposed in 2016 that recognises three genera within the subfamily Callicebinae; Plecturocebus Byrne et al., 2016 for the Amazonian and Chaco ...
In this regard, lemurs are popularly confused with ancestral primates; however, lemurs did not give rise to monkeys and apes, but evolved independently on Madagascar. [1] Primates first evolved sometime between the Middle Cretaceous and the early Paleocene periods on either the supercontinent of Laurasia or in Africa. [2]
Black-and-white colobuses (or colobi) are Old World monkeys of the genus Colobus, native to Africa. They are closely related to the red colobus monkeys of genus Piliocolobus. [1] There are five species of this monkey, and at least eight subspecies. [1] They are generally found in high-density forests where they forage on leaves, flowers and fruit.
The gelada (Theropithecus gelada, Amharic: ጭላዳ, romanized: č̣əlada, Oromo: Jaldeessa daabee), sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of 1,800–4,400 m (5,900–14,400 ft) above sea level.
