Monkey Business: Exploring The Fascinating World Of New World Monkeys
The New World monkeys are a diverse group of arboreal primates that inhabit a range of forest habitats, from Mexico to Argentina. You can read more about these fascinating primates in this article.
The species of New World monkeys are Marmosets, Tamarins, Squirrel monkeys, and Uakaris. In addition to being extremely fun to watch, these animals make excellent pets.
Marmosets
The family of New World monkeys, Callitrichidae, contains marmosets, tamarins, and lion tamarins.
Historically, the family was thought of as a subfamily of the Cebidae, but that is no longer the case. Marmosets are one of the most well-known primates.
Marmosets live in Central America and South America, while lion tamarins are found in the rainforests of Africa and Asia.
The name marmoset comes from a French word that means “shrimp.” It refers to the smallest true monkey. Their lower teeth are used to gnaw tree bark and drink its sap.
Both tree sap and nectar are valuable to marmosets. This makes them an excellent choice for pets and research. Marmosets are considered among the most adorable monkey species, so if you’d like to see them in their natural habitat, consider making a donation.
Unlike most monkeys, marmosets’ reproductive habits are suppressed. This is done by a cooperative breeding system that prevents sexual behavior and ovulation in all females.
The reproductive suppression process is probably accomplished through pheromonal signals from the breeding female and non-specific behavioral cues.
When captive callitrichids encounter a disturbance in their environment, they exhibit high levels of aggression and excessive arousal.
Tamarins
Like most monkeys, tamarins are gregarious and social creatures.
They live in social groups of three to nine members and form short-term associations with each other. These groups may be as large as 19 members.
They form groups with clearly defined boundaries and have complex vocal repertoires consisting of 38 distinct sounds that conform to grammatical rules.
Tamarins use vocalizations to convey emotions such as fear, curiosity, playfulness, and warnings. Marmosets and tamarins live in social groups, although they are smaller than marmosets.
Tamarins and marmosets often live in larger groups than do tamarins, and callitrichids are unusual in several ways.
Their reproductive systems vary, and they exhibit polygyny and polyandry. Groups of callitrichids consist of a breeding female and up to two nonbreeding males.
These nonbreeding males assist with infant care. In addition, marmosets and tamarins share nesting territories. While some species exhibit no soliciting behavior, they are known to engage in “callitrichid” mating behavior.
While callitrichids are very territorial, they display high levels of threat in crowded colonies. Some species have also been shown to suffer high rates of infant loss and abortion when captive-bred.
In addition, the proximity of neighboring groups may cause a high incidence of chronic arousal.
Squirrel Monkeys
Squirrel monkeys inhabit tropical forests in Central and South America, residing in the canopy layer.
Although most species of squirrel monkeys live in the Amazon, S. Oerstedii is disjunctly distributed throughout Costa Rica.
Its name ‘miss Baker’ refers to an ‘astronaut’ squirrel monkey, which rode into space as part of the United States space program. Its short, close fur is yellowish orange or black on the back and shoulders. The upper body is hairy.
Squirrel monkeys form multi-female groups, which sometimes exceed 500 members. They feed in large groups, but can sometimes break up into smaller groups.
Despite the fact that females outnumber males, the society of this species revolves around the females, who control territorial disputes and the spatial relations among troop members.
A male’s role in a troop’s life depends on his ability to attract females. Common Squirrel Monkeys are similar in appearance to their larger counterparts.
Their ears are rounded, while their eyes are white. They have a black widow’s peak above their nose and short, dense fur on their bodies.
They lack prehensile tails, but their long, soft tail is useful for climbing high branches. These monkeys have a long tail that often rests over the shoulder.
Uakaris
If you’ve ever wondered about the biology of uakaris, you’ve come to the right place.
These New World monkeys are particularly vulnerable to blood-borne parasites. Their highest infection rates were among all other NWMs.
Moreover, the species is prone to trypanosomatids, which have 100% infection rates in wild populations. Moreover, their facial coloration may indicate the physiological effects of parasites.
Uakaris are arboreal quadrupeds that prefer to traverse the middle and upper portions of the forest canopy. As a result, they rarely move on two feet and instead, jump and run between branches and supports.
The young of this species begin eating soft fruit between the age of three and five months. In captivity, they may live into their mid-thirties.
The uakari, whose name is also spelled ouakari, inhabit the rainforests at all levels and rarely touch the ground. They live in social groups of up to 30 members and are better adapted to leaping between branches than descending to the ground.
Female uakaris are territorial and give birth to a single offspring every two years. Their gestation period is about 180 days.
The uakaris are specialized seed predators, which live in larger groups of twenty to thirty individuals. They look similar to saki monkeys but have shorter tails and specialized teeth.
The red uakaris are particularly noticeable in their appearance, with a red face and a bald face. Their black-headed counterparts are less striking, with white fur and a vermilion face.
White-Faced Saki
While the White-faced Saki is a monogamous species, in the wild, they may form polygamous pairs or even have several mates.
These monkeys are protected by conservation status Least Concern, but the pet trade has reduced their numbers. Learn more about this fascinating species and all of its interesting facts in the following paragraphs. Read on to learn more about these beautiful monkeys!
The white-faced saki is a unique species based on its diet. Most frugivorous species eat only ripe fruits, while the white-faced saki prefers unripe fruits.
As such, they occupy a unique ecological niche. But, their unusual diet may explain their bizarre behavior. They also eat seeds, so they’re not just eating fruit that’s been ripe.
While the White-faced saki is also known as the golden-faced saki, the two species differ in their size. Males are slightly smaller than females, with males weighing 5.25 lb (2.38 kg), while females are slightly lighter.
In fact, the male white-faced saki is slightly larger than the female, but they have similar physical features. While the White-faced saki is a rare sight in the wild, it is easy to find captive examples, as they are difficult to reintroduce to their native habitat.
However, these monkeys are well-suited as family pets. Their habitat ranges in rainforests in the forests of South America. They prefer trees that produce a wide variety of fruits and seeds, and they live at canopy heights of 50 to 80 feet.
Platyrrhine
New World monkeys are members of the Platyrrhini taxonomic family.
They separated from Old World monkeys and apes around 40 million years ago. They are thought to have spread to the Americas by island hopping or on rafts of vegetation.
Extant species are divided into five families and twenty genera. Several taxa are subject to change, however. Although most New World monkeys are not aggressive, they are capable of delivering a sharp bite when threatened.
They may try to explore human habitats or climb on them. When frightened or pushed away, these animals may bite vigorously.
In addition, if they have previously been housed as pets, they may develop a strong attachment to humans and may even bite to “defend” their favored people.
Unlike Old World monkeys, New World monkeys are more likely to live in forests with thick vegetation. Their dense forest habitats also provide excellent food sources. They live in a variety of habitats in South and Central America, including the Caribbean and the Amazon.
Although they may seem small, they are among the smallest anthropoid primates. New-World monkeys can range from less than a kilogram to ten kilograms.
They are isolated radiation, but they provide important living analogs to reconstruct extinct primates. Cebid monkeys are arboreal tree dwellers.
They feed on fruits and leaves, and also on birds’ eggs and bark-dwelling insects. The only New World monkeys that are nocturnal are night monkeys.
All other New World monkeys are diurnal. You can’t really expect a monkey to feed you in captivity unless you want to risk exposing your family to disease.
Types Of New World Monkeys
Rank | Family | Examples |
---|---|---|
1 | Callitrichidae | Marmosets, tamarins |
2 | Cebidae | Capuchins, squirrel monkeys |
3 | Aotidae | Night monkeys |
4 | Pitheciidae | Titis, sakis, uakaris |

Author:
CARLOS AUGUSTO DELMINDO FILHO
In vitro embryo production (IVP) has revolutionized cattle reproduction, allowing for the rapid multiplication of genetic material from high-value animals and opening up new possibilities for genetic improvement. Gene editing, with emphasis on the CRISPR-Cas9 technique, emerges as a powerful tool to enhance IVP, enabling precise manipulation of the genome and the introduction of desirable characteristics in animals. Gene editing techniques, such as CRISPR-Cas9, ZFNs, and TALENs, allow for precise modification of DNA at specific locations, representing an advance over homologous recombination techniques, which are inefficient and time-consuming.
However, the application of gene editing in bovine embryos generated by IVF still presents technical challenges, such as low efficiency and the occurrence of mosaicism, in addition to ethical and regulatory considerations that need to be addressed. This article discusses the potential and challenges of gene editing, focusing on the CRISPR-Cas9 technique, in bovine embryos produced by IVF, aiming to develop strategies to overcome barriers and ensure the safe and responsible application of this promising technology.
Potential of Gene Editing in Bovine Embryos
CRISPR-Cas9 gene editing allows for precise manipulation of the genome, opening up a range of possibilities for genetic improvement in cattle. The technique can be used for:
- Correction of disease-causing genes: Recessive genetic diseases, such as Bovine Leukocyte Adhesion Deficiency (BLAD), can be corrected in embryos, eliminating the transmission of the disease to future generations.
- Insertion of beneficial traits: The introduction of genes of interest, such as disease resistance or production traits, can accelerate the genetic improvement process, resulting in healthier and more productive animals.
- Creation of models for research: Gene editing allows for the creation of animal models to study human diseases and develop new therapies.
Challenges of Gene Editing in Bovine Embryos
Despite the potential, gene editing in bovine embryos still faces challenges:
- Efficiency of editing: The success rate of gene editing in embryos is still relatively low, with the frequent occurrence of mosaicism (different genotypes in the same individual).
- Editing specificity: The technique can generate unintentional mutations in other parts of the genome, with possible undesired effects.
- Generation of viable animals: Gene editing can affect embryonic development and the viability of the generated animals.
- Ethical and regulatory aspects: The application of gene editing in animals raises ethical questions about animal welfare and food safety, in addition to demanding a clear and consistent regulatory framework.
Strategies to Overcome Challenges
To overcome the challenges of gene editing in bovine embryos, several strategies are being explored:
- Optimization of editing protocols: Optimization of gene editing protocols, such as the use of different CRISPR-Cas9 systems and choosing the ideal time for editing, can increase the efficiency and specificity of the technique.
- Selection of edited embryos: The combination of gene editing with genomic selection of embryos (GSE) allows the identification and selection of embryos with the desired editing and high genetic merit, increasing the efficiency of the process.
- Improvement of embryo transfer techniques: The development of more efficient embryo transfer techniques can increase the success rate in generating viable animals from edited embryos.
- Ethical discussion and development of regulations: Ethical debate and the development of clear and consistent regulations are fundamental to ensure the responsible and safe application of gene editing in animals.
Conclusion
CRISPR-Cas9 gene editing represents a powerful tool for the advancement of animal production and food security, as long as it is used responsibly and ethically. The combination of gene editing with other biotechnologies, such as genomic selection, can accelerate the development of solutions for livestock challenges, such as diseases, low productivity, and adaptation to climate change. However, it is crucial that the scientific community and society engage in a constant dialogue to ensure that the application of gene editing is safe, transparent, and benefits both producers and consumers.
Gene editing, especially with the CRISPR-Cas9 technique, has enormous potential to revolutionize in vitro embryo production (IVP) and genetic improvement of cattle, opening doors to a promising future in livestock. By enabling precise manipulation of the genome, this technology allows the correction of disease-causing genes, the insertion of beneficial traits, and the creation of models for research in cattle. Overcoming technical challenges, such as increasing the efficiency and specificity of editing, along with the combination with other biotechnologies, such as genomic selection of embryos, has the potential to accelerate genetic improvement and boost IVP, resulting in healthier, more productive, and better-adapted animals to market needs.
However, the application of gene editing in bovine embryos also raises important ethical and regulatory questions. It is essential that the scientific community, together with regulatory bodies and society, establish an open and transparent dialogue to discuss the possible impacts of this technology and ensure its responsible and safe application. Additionally, the development of a clear and consistent regulatory framework is essential to ensure food safety, animal welfare, and consumer confidence in products derived from gene editing.
