What does durukuli mean?
The durukuli is a small monkey native to Central and South America, belonging to the genus Aotus and better known today as the night monkey or owl monkey. It is remarkable among primates for being fully nocturnal: its large, forward-facing eyes give it excellent night vision, while its rounded head and subtle facial markings lend it something of an owl-like appearance, hence its alternative English names. Durukulis live in family groups in tropical forests, feeding on fruit, leaves, insects, and other small prey during the hours after dusk. The word itself derives ultimately from indigenous South American languages and entered European scientific writing through French, where the variant form "douroucouli" remains common. Although the term now appears mainly in zoological literature, it offers an evocative glimpse into the rich naming traditions that early naturalists drew upon when cataloguing the fauna of the New World tropics.
nounA small nocturnal South American monkey of the genus Aotus (especially Aotus trivirgatus), also known as the night monkey or owl monkey, having large eyes and a rounded head.
- A nocturnal South American monkey of the genus Aotus; a night monkey or owl monkey.
"In the moonlit canopy of the Amazon, a durukuli stirred from its hollow-tree refuge to begin the night's foraging."
"Field researchers studying Aotus trivirgatus often refer to their subject simply as the durukuli."
"Zoos keep durukulis in dimly lit enclosures to accommodate their strictly nocturnal habits."
Regular English plural; occasionally left uninflected in older zoological writing.
"The sanctuary houses three durukulis rescued from the illegal pet trade."
The durukuli is one of the world's only truly nocturnal monkeys — it has no tapetum lucidum in its eyes, yet still navigates the dark forest better than most primates manage by day.

Etymology of durukuli
The word "durukuli" entered English from French "douroucouli," a borrowing ultimately traced to an indigenous South American language of the Tupi-Guarani family, whose speakers inhabited regions where the animal occurs. Naturalists adopted the term in the nineteenth century when describing the nocturnal monkeys of the Neotropics. Because of its transmission through French, several variant spellings exist, with "douroucouli" being especially widespread in older zoological texts.
How durukuli is actually used
The term is chiefly zoological and somewhat dated or literary; "night monkey" and "owl monkey" are the standard common names in modern scientific usage. Spelling varies considerably, with "douroucouli" being the more widely encountered form.
Easily confused with durukuli
Douroucouli is simply an alternative spelling of the same word (via French); both name the same nocturnal monkey.
