The pygmy marmoset, genus Cebuella, is a small genus of New Earth monkey native to rainforests of the western Amazon Basin in South America. Information technology is notable for existence the smallest monkey and one of the smallest primates in the world, at merely over 100 grams (3.5 oz). It is generally found in evergreen and river-edge forests and is a gum-feeding specialist, or a gummivore.

Well-nigh 83% of the pygmy marmoset population lives in stable troops of ii to nine individuals, including a dominant male, a breeding female, and upwards to four successive litters of offspring. The modal size of a standard stable troop would be six individuals.^[3] Although about groups consist of family members, some may too include ane or 2 additional adult members. Members of the group communicate using a complex organization including vocal, chemical, and visual signals. Three main calling signals depend on the distance the call needs to travel. These monkeys may also make visual displays when threatened or to prove potency. Chemical signaling using secretions from glands on the chest and genital area allow the female to indicate to the male person when she is able to reproduce. The female gives birth to twins twice a year and the parental care is shared betwixt the group.

The pygmy marmoset has been viewed equally somewhat different from typical marmosets, most of which are classified in the genera Callithrix and Mico, and thus is accorded its own genus, Cebuella, inside the family Callitrichidae. The biggest threats are habitat loss and the pet trade.^[four]

Development and taxonomy [edit]

There has been debate amongst primatologists concerning the proper genus in which to place the pygmy marmoset. An examination of the interstitial retinol binding poly peptide nuclear gene (IRBP) in three marmoset species showed that Callithrix equally constructed in the 1990s also needed to include C. pygmaea to be monophyletic, and that the times of separation of pygmaea and the argentata and jacchus species groups from ane another are less than 5 one thousand thousand years ago, as might be expected for species of the aforementioned genus.^[five] However, subsequent separation of the argentata and jacchus species groups into different genera (the argentata group having been moved to Mico) justifies maintaining a separate genus for the pygmy marmoset, equally Callithrix is no longer paraphyletic.^[6]

There are 2 species described of the pygmy marmoset:^{[i] [two]}

• Cebuella pygmaea – Western pygmy marmoset
• Cebuella niveiventris – Eastern pygmy marmoset

There are few morphological differences betwixt these species, as they may only differ slightly in color, and they are just separated by geographical barriers, including large rivers in South America.^[7]

The evolution of this genus diverged in terms of body-mass from typical primates, with a high rate of trunk-mass reduction. This involves large decreases in pre-natal and post-natal growth rates, furthering the thought that pro-genesis played a role in the evolution of this animal.^[8]

Physical clarification [edit]

The pygmy marmoset is the world'southward smallest monkey.

Skull of a Pygmy marmoset

The pygmy marmoset is one of the world's smallest primates, being the smallest truthful monkey, with a head-trunk length ranging from 117 to 152 mm (four.6 to half dozen.0 in) and a tail of 172 to 229 mm (vi.8 to 9.0 in). The average adult body weight is just over 100 grams (three.5 oz) with the just sexual dimorphism of females beingness a little heavier.^{[nine] [10]} The fur colour is a mixture of dark-brown-gilt, grey, and black on its back and head and yellow, orange, and tawny on its underparts. Its tail has black rings and its confront has flecks of white on its cheeks and a white vertical line between its eyes.^[10] It has many adaptations for arboreal living including the ability to rotate its head 180 degrees and sharp claw-like nails used to cling to branches and trees.^{[11] [12]} Its dental morphology is adapted to feeding on mucilage, with specialised incisors that are used to gouge trees and stimulate sap flow. Its cecum is larger than usual to allow for the greater period of fourth dimension gum takes to suspension downwardly in the stomach.^[12] The pygmy marmoset walks on all 4 limbs and can spring up to v m (16 ft) between branches.^{[11] [13]}

Environmental [edit]

Geographic range and habitat [edit]

The pygmy marmoset can be plant in much of the western Amazon Basin, in Brazil, Colombia, Ecuador, Peru, and Bolivia. The western pygmy marmoset, Cebuella pygmaea pygmaea, occurs in the state of Amazonas, Brazil, eastern Republic of peru, southern Colombia, and north-eastern Ecuador. The eastern pygmy marmoset, C. p. niveiventris, is too constitute in Amazonas, just too in Acre, Brazil, eastern Republic of peru, and northern Bolivia. The distribution of both subspecies is often limited by rivers. It typically lives in the understory of the mature evergreen forests and often nearly rivers.^[6] Population density is correlated with food tree availability. Information technology tin can be found between footing level and about 20 metres (66 ft) into the trees but generally does not enter the top of the canopy. It is often constitute in areas with continuing water for more than three months of the year.^[10]

Diet [edit]

Specialised claws allow the pygmy marmoset to cling to trees while feeding.

This monkey has a specialized diet of tree gum. It gnaws holes in the bark of appropriate trees and vines with its specialized dentition to elicit the product of glue. When the sap puddles up in the pigsty, it laps it up with its tongue. Information technology likewise lies in wait for insects, especially butterflies, which are attracted to the sap holes. It supplements its diet with nectar and fruit.^[14] A group's home range is 0.1 to 0.iv hectares (0.25 to 0.99 acres), and feeding is usually concentrated on one or two copse at a fourth dimension. When those go depleted, a grouping moves to a new habitation range. Brown-mantled tamarins are generally sympatric with pygmy marmosets and often raid pygmy marmosets' gum holes.^{[half dozen]}

Pygmy marmosets accept adapted insect-similar claws, known as tegulae, to appoint in a loftier degree of claw-clinging behaviors associated with plant exudate exploitation. Exudate is any material that oozes out of a establish, including gum, sap, resin, and latex.^[xv] Hook-clinging is primarily used during feeding, but as well during institute exudate foraging.^[13]

Behaviour [edit]

A pygmy marmoset group, ranging from two to nine members, contains one or ii adult males and i or 2 developed females, including a unmarried breeding female and her offspring.^[16] Interbirth interval ranges from 149–746 days.^[17] In contrast to other callitrichines, there is no relationship betwixt the number of adult males and the number of infants and offspring. Nonetheless, there is a significant positive relationship between the number of juveniles and the number of adult and sub-adult grouping members.^[18] Young marmosets typically remain in the grouping for two sequent birth cycles. The pygmy marmoset uses special types of advice to give alerts and warning to its family members. These include chemical, vocal, and visual types of advice.^[19] It is believed to serve to promote grouping cohesion and avoidance of other family groups.^[20]

[edit]

Infant pygmy marmosets, along with their parents, twin, and other siblings, form cooperative care groups. Babbling, or vocalizing, by the baby marmoset is a key part of its relationships with its family members and is a major role of its development. As the infant develops, the blathering gradually changes to resemble and somewhen go adult vocalization. There are many similarities betwixt the development of vox in infant pygmy marmosets and speech in infant humans. Vocalizing gives the babe advantages such as increased care and allows the entire family unit to coordinate their activities without seeing each other.^[21]

Pygmy marmosets alive in groups of 2 to nine individuals.

Siblings as well participate in baby intendance. Infant marmosets require the most attention, then having more family members participating in the care decreases the price for any individual and also teaches parenting skills to the juvenile marmosets. Members of the group, usually female, may even put off their ain reproduction through a temporary cessation of ovulation in order to intendance for the offspring of others in the grouping. The ideal number of caregivers for an infant marmoset has been shown to exist around v individuals. Caregivers are responsible for finding food for the infants too as helping the father watch for predators.^[22]

The pygmy marmoset is a non-seasonal breeder and ordinarily gives nascence to twins one time or twice a year.^[23] All the same, unmarried births occur 16% of the time and triplet births viii% of the fourth dimension.^[17] The pygmy marmoset is usually monogamous though at that place is some variation within the species in terms of convenance systems. Polyandry as well occurs every bit male marmosets are responsible for carrying the infants on their backs. Having a 2d male person to bear the offspring can exist benign every bit marmoset litters are often twins and decreases the cost to whatever detail male. The daily range of the pygmy marmoset, all the same, is relatively small-scale, which decreases the rate of polyandry.^[24]

Male and female pygmy marmosets bear witness differences in foraging and feeding behavior, although male person and female dominance and aggressive behavior varies within the species. Males have less time to search out food sources and provender due to the constraints of their infant caring responsibilities and predator vigilance. Without an infant to conduct, female pygmy marmosets have greater liberty to forage, giving them an apparent feeding priority. This priority may serve to compensate mothers for the energetic costs of conveying and lactating for two offspring at a time. Even so, the fact that feeding priority is as well given to females without offspring weakens the statement. Instead, female feeding priority may have evolved through sexual selection. Females may choose mates who invest more time in infant intendance and predator vigilance. Such males have less fourth dimension to look for food, assuasive the female person feeding priority.^[25]

Communication [edit]

Groups employ contact calls to stay together when foraging, feeding, and travelling.

The pygmy marmoset is well known for its advice abilities including an intricate organisation of calls. The trill is used during feeding, foraging, and when travelling and the grouping is shut together. The J-phone call is a series of fast notes repeated by the caller and is used at medium distances. Both calls are used as contact calls. The long call is used when the grouping is spread out over distances greater than 10 meters or in response to a neighboring group.^[19] The pygmy marmoset uses the trill for brusk-distance advice, J-calls for intermediate distances, and long calls for long distances; these accept respectively decreasing frequencies. Pigmy marmosets interpret these calls not only by type but also, through subtle sonic variance, past individual calling. Research based on audio playback tests shows that calls recorded from different individuals in captivity varied significantly in all seven auditory parameters analyzed for each type of call. Behavioral responses to trills were greatest when the caller was the dominant male of the group. Responses to J-calls were greatest when the caller was the monkey's mate or a same-sexual practice monkey from exterior the grouping. Varying responses to individual callers were but observed when the call was given spontaneously from some other creature rather than beingness played back from a recording, with 1 exception. That exception was that male monkeys responded to playbacks of their own calls differently from those of other monkeys, when the call was played back from a familiar location. Information technology is thought the pygmy marmoset reacts at starting time to the type of call that is existence made and and then adjusts its behavior slightly to react to the specific individual that is making the call. This allows the marmoset to react appropriately to all calls but show some variation when the call gives extra information.^[xx]

Environmental factors play a part in communication by affecting the frequency of the indicate and how far the betoken can travel and still be audible to communicate the desired message. Since the pygmy marmoset is oftentimes plant in the rain forest, found life and the humid atmosphere add to the normal assimilation and scattering of sound. Because depression frequency calls are afflicted less by the disturbances than their high frequency counterparts, they are used for communication beyond longer distances.^[19] The pygmy marmoset changes the characteristics of its calls when its social environment is changed. Adult marmosets volition show modifications in the structure of their calls which mimic that of their group members. In improver to changes of existing calls, novel calls may be heard from marmosets later pairing.^[26]

The pygmy marmoset has other ways to communicate information about matters such as the female'southward ovulatory land. New World monkeys do not prove genital swelling during ovulation as female Old Globe monkeys do. Instead, a lack of female aggression towards males tin can serve equally a signal of ovulation. Scent glands on its chest, anus, and genitals are also rubbed on surfaces which leave chemical signals about the reproductive country of the female.^[27] The pygmy marmoset also performs visual displays such as strutting, back-arching, and piloerection when information technology feels threatened or to show dominance.^[28]

Conservation [edit]

They are threatened past habitat loss in some areas of its range, and by the pet trade in others (i.east. Republic of ecuador).^[6] Interaction between humans and the pygmy marmoset is associated with a number of behavioral changes in the fauna including social play and vocalization, both of which are important to communication between animals in the species. Specially in areas of heavy tourism, pygmy marmosets accept a tendency to be less noisy, less aggressive, and less playful with other individuals. They are too pushed into college strata of the rainforest than they would commonly adopt. Tourism in areas native to the pygmy marmoset is as well correlated with increased capture of the animal. Due to its small size and relatively docile nature, captured pygmy marmosets are often found in exotic pet trades.^[29] Capture causes fifty-fifty more behavioral variations, including a decrease in both the number and the audio level of vocalizations.^[30] Pygmy marmosets can also be found at local zoos, where they exist in groups.^[31]

As pets [edit]

Finger monkeys' (pygmy marmoset) value is associated with them being the smallest primate in the earth. New-born pygmy marmosets are usually five–6 inches (130–150 mm) tall, and weigh from 100 grams (three.v oz).^[32] Although these primates are not in danger of extinction, they are rare to find in the marketplace for purchase. Prices range from $ane,000 to $4,000.^[32] Mostly, a pygmy marmoset'due south life span is from fifteen to twenty years, they are known to have a shorter life in the wild mainly because they fall out of trees.^[33]

Another expense for these creatures as pets is the necessary essentials in order to maintain them. Creating an environment similar to that of where they are from is important.^[34] For food, these creatures equally pets are often fed fruits, insects, and smaller lizards.^[35] As pets, a baby pygmy marmoset needs to exist fed every 2 hours for at least 2 weeks.^[32] Agreement their natural diet is also important considering it helps maintain their proficient health from the necessary protein, calcium and other nutritional sources they demand in order to survive.

In the United States, each state has different regulations when it comes to owning i of these creatures.^[32] Another cistron that needs to be considered is that a regular veterinarian might not be able to help provide medical evaluations or care; one would need to seek out a veterinarian with a primate specialization.^[33] In Due south America it is illegal to either import or export these creatures. Understanding the laws within those countries is important when it comes to considering owning or taking care of a pygmy marmoset. Many people do not agree that pygmy marmosets should be pets.^[34] The statement is usually that they have a longer life span when they are in good care from a human being.^[35] All the same, the UK RSPCA says they should "non be considered as pets in the accepted sense of the give-and-take. They are wild undomesticated animals that cannot be business firm-trained or fully tamed".^[36]

In popular culture [edit]

• Fingerlings, the hitting toy of Christmas 2017 produced past WowWee, is based on pygmy marmosets.^[37]
