Night monkeys have large eyes which improve their vision at night, while their ears are mostly hidden, giving them their name Aotus, meaning "earless". Night monkeys are the only truly nocturnal monkeys with the exception of some cathemeral populations of Azara's night monkey, who have irregular bursts of activity during day and night.
Mar 13, 2024 · The owl monkeys are a group of 10 species in the genus Aotus, split into two groups. Previously the genus just contained one species with several subspecies, but all have since been elevated to...

Our findings showed different MT-CO1, MT-CO2, MT-CYB and SRY haplotypes between Aotus species although some SRY haplotypes differed by only one nucleotide (see Figure 2A), as was the case of A. infulatus (IN2) when compared to A. azarae boliviensis (AB1) and A. nigriceps(NI2). Identification based on MT-CO2was shown to be unreliable for closely rel...
Analyses of the different datasets showed that Dat-CO1 contained the highest number of PI sites (182), closely followed by Dat-CYB (181), while Dat-CO2, showed the lowest number (66). This might be related to the smaller size of MT-CO2 (696 bp) respective to MT-CO1 (1,557 bp) and MT-CYB (1,140 bp) although a similar number of PI sites was found in ...
Our phylogenetic reconstructions question the classical grouping of red neck and grey neck species proposed by Hershkovitz . All phylogenetic reconstructions based on mtDNA showed that the lineage leading to the grey neck species A. trivirgatus was a sister lineage of the one leading to the red neck clade (A. nigriceps (A. azarae, A. infulatus)). I...

First described in 1823 by German naturalist Johann Baptist von Spix, Spix’s night monkey (Aotus vociferans)—also known as the Colombian gray night monkey, noisy night monkey, or Spix’s owl monkey—is found north of the Amazon River in Brazil, Colombia, Ecuador, and Peru. Its range is limited by geographical barriers: the…
May 21, 2009 · You could probably guess by looking at its large round eyes that it’s nocturnal, and indeed, it is the only monkey to be mostly active at night. But its eyes have many adaptations for such a ...
Jul 18, 2005 · Some of the intrepid owl monkey researchers and contributors to the knowledge of wild Aotus include Patricia Wright (Peru and Paraguay), Rolando Aquino and Filomeno Encarnación (Peru), and Eduardo Fernandez-Duque (Argentina).
