What is a Finger Monkey?

From this new world monkey group consisting of marmosets, tamarins, and lion tamarins; the finger monkey is the smallest known primate weighing about 100 grams for adults.

The finger monkey is indigenous to South America, precisely the rainforest of the Amazon Basin. Living in the world, the Callitrichidae family is now arboreal; adapted to wildlife, and especially the trees.

They are gumivores feeding on the sap and gum from evergreen riparian forest trees close to the river. However, that’s not all they feed on as you will learn shortly.

Baby Finger Monkey Size

A newborn pygmy marmoset measures five inches tall with a weight of only 15 grams. They are very delicate at this time seeing as they are in the most vulnerable stage in their life cycle.

Within the first two weeks to a month, the baby marmoset is completely dependent on its parents.

The mothers tend to nurse the babies as fathers carry them on their backs. This is very risky as their mortality is threatened with the possibility of the baby falling from their fathers back.

However, after two you three months, weaning begins and the baby’s life is no longer under threat.

Can I Have a Finger Monkey as a Pet?

Monkeys are primarily primates meaning they are able to communicate and cohabitate with human beings. However, certain traits may question their suitability as to whether they’ll be good pets. Let’s debate!

Why They are Good

  • Peaceful, fun, and loving temperament. They love to play and cuddle.
  • Quite easy to maintain once you get the hang of it.
  • Not tiresome to carry around.

Why They May Not Be Good

  • They are costly – besides the purchase amount of about $1500 to $4000 you spend, you have to invest in food, living conditions, medical and health matters, plus other requirements.
  • It’s illegal to ship them into certain states. If you fall under these states, it’s not worth the hustle.
  • They can be very clingy – especially to your finger. 
  • Primates are unpredictable, have a sense of independence (especially for adults), and could be carriers of unknown diseases.

Diet (Baby & Adults)

As you’ve read from above, pygmy marmosets are primarily gumivores that feed on gum, sap, and other exudates such as latex from evergreen riparian forest trees. This is what they’re naturally and scientifically bred to do, but that’s the case for those that live in the wild.

Diet: what do finger monkey eat?

Pet marmosets have a somewhat better diet. Newborn pygmies will use infant formula for the first two weeks preceding the second month they when the weaning begins.

They also feed on insects, especially butterflies, which would be attracted to the sap from the tree.

In addition, they would feed on arthropods, plant parts, several other insects, and tiny reptiles.

While in captivity, you can give them insects such as mealworms, waxworms, grasshoppers, and crickets. You can also get store-bought kibble; its a combination of crushed and dried insects.

As the exudates from the trees are not highly sourced with proteins, carbohydrates, and calcium; a supplementary diet is required.

The diet could include boiled eggs, lots of different proteins like chicken, fish, turkey, grains, cereals, plenty of fruits, and vegetables. In terms of hydration, water is very essential. You can also include milk from a goat, fresh fruit juice, and sap.

Habits (Baby & Adults)

Finger monkeys are free-spirited; therefore, they enjoy active sports when they aren’t feeding. They are also very clingy to its owner, especially if you own another pet. Adult pocket monkeys can often be aggressive when they don’t get what they want or when hungry. Despite that, they are very calm and self-absorbent.

Adult finger monkeys love to associate in groups, that could be from two to nine individuals; one or two adult males and one or two adult females.

They appreciate a sense of belonging, which is why they would feel threatened if a poacher was to abduct their kind. However, as rare and exotic they are, they’re equally threatened by nature’s predators.

The female species has a unique gene that allows them to mate and give birth to twins or triplets even twice a year.

As habit indicates once they are fully matured, they need to mate and reproduce to ensure the continuous cycle of life. Mating season occurs within the months of May and June and November through January.

To instill independence in their children, the parents will leave their two weeks old baby in a secluded and protected place and heads out to forage in the trees. This way the baby begins to relieve their burden of dependence on their parents.

Last but not least, as the marmosets grow older, they become more and more unpredictable – even with previous training. They lack patience and get bored easily hence, they need to engage more often.

Do They Bite?

Yes, finger monkeys can bite using their sharp teeth in times when they feel threatened or hungry. Their passive aggression causes them to attack using their teeth, scratch with their sharp claws, throw feces on their owners among other instincts.

Since they are seen as very tiny mammals, once vulnerable they tend to be very aggressive; sometimes too aggressive. As a mode of self-defense, they attack vigorously as females appear more aggressive and even less tolerant as they age.

In a quest to maintain a wildlife feel, the cage needs to be installed with swings, artificial or real branches from trees, and some leaves.

Those will act as toys and aid the monkey not to get bored or lethargic. Ideally, the cage should be placed under direct sunlight or a heat source like a lamp, fireplace, or any other ultraviolet light sources.

Heat/ warmth is an essential requirement for these pygmies since they are very prone to getting common colds and chickenpox.

Lastly, the water supply. They also need plenty of access to water in their cages to keep them hydrated all day.
