Uakari
genus of mammals
Uakari (UK: , US: ) is the common name for the New World monkeys from the genus Cacajao. Both the English and scientific names are believed to have originated from indigenous languages.
The uakaris are unusual among New World monkeys in that the tail length (15–18 cm) is substantially less than their head and body length (40–45 cm). Their bodies are covered with long, loose hair but their heads are bald. They have almost no subcutaneous fat, so their bald faces appear almost skull-like. Like their closest relatives the saki monkeys, they have projecting lower incisors. These monkeys have the most striking red facial skin of any primate. Females choose their mates based on how red the male's face is. Evidence suggests that the red facial coloration reflects the health of the primate.
The four species of uakari currently recognized are all found in the north-western Amazon basin.

Why this record matters
“Uakari” is worth following because a concise public description often conceals a longer documentary argument. Here, Uakari, genus and mammals provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q1048171. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
