Proboscis Monkey

Nasalis larvatus 





Taxonomy 
    The Proboscis monkey, also know as the Nasalis larvatus is an incredibly diverse spices found within the primate family. They are classified under the suborder Haplorrhine within the infraorder Simiiformes and superfamily Cercopithecoidea. The belong to the family Cercopithecoidea , the subfamily Colobinae, their genus is Nasalis, and they are scientifically called Nasalis larvatus (Proboscis Monkey - Wisconsin National Primate Research Center, n.d.). These not so little guys are commanly refered to as long-nosed monkey and or the bekantan. 



 
Morphology
     Morphologically, Proboscis display multiple distinct physical traits that set them apart from other primates. Males are most commonly known for their long pendulous nose, which can be significantly long exceeding 10 cm in length according to the Wisconsin National Primate Research Center. Adult males can measure about 76 cm in height and weigh around 16 to 22kg , while the females are smaller being about 61 cm and weighing 7 to 12 kg. (Amy Woltanski, n.d.).  They are also some of the few primates that can swim with an adaption of having webbed toes that allow them to navigate their coastal homes.

Life History
    Proboscis exhibit series of developmental milestones that reflect their biological and their social life. They have a wide lifespan of up to 20 years and 23 years in captivity while their gestation period has an average of 166 day according to Amy Woltanski. After birth the young will stay with the mothers for about 6 to 7 months. They go through distinct stage of development: infant, subadult, and adult with the males reaching sexually maturity around 5 to 7 years old. During this time they develop social bonds living in groups led by a alpha male whose job is to protect everyone.  

Conservation Status
    As a species they face threats as they are leading towards the classification of endangered. Due to the habit lost of mangroves and lowland tropical forest. According to Millie Bond their are approximately 7,000 left today in the wild. While they are banned from being hunted that doesn't stop the deforestation of mangroves and lose of habitat. According to the New England Primate Conservancy there are programs that are focused on protecting these wild animals by creating suitable environments for them to live in  and try to reduce the deforestation efforts. They have also created shows about them to talk about how awesome they are an example is The Wild Kratts where they teach kids about many animals and Probiscis monkeys have made an apparency.

  Golden Snub-Nosed Monkeys Olivia Isetts-Williams ID: The wild golden snub-nosed monkeys in Shaanxi’s Qinling Mountains ( China Daily, 2025 ) Taxonomy ID: Primate Taxonomy Chart ( Prehistoric and Contemporary Primates,  University of Minnesota Duluth )   The Snub-Nosed Monkeys, under the grand order of the primates, belong to the primary suborder of Haplorrhini. Moving beyond that, they are identified as the infraorder Simiiformes, which branches into the parvorder Catarrhini—establishing them as old world monkeys—and are further clarified under said identifier with the Cercopithicoidea superfamily. The genus of the Snub-Nosed Monkeys are the Rhinopithecus, as a Greek ode to their unique noses. These distinctive primates can be characterized by five different species: The Yunnan (Rhinopithecus  bieti ), Grey (Rhinopithecus  brelichi ), Tonkin (Rhinopithecus  avunculus ),  Myanmar (Rhinopithecus  strykeri ), and Golden Snub-Nosed Monkeys, though t...
