Black Tufted Marmoset

(Last Updated On: April 9, 2021)

Black tufted Marmoset (Callithrix penicillata) is considered as one of the New World monkeys under the order of the Primates.

Primates are one of the most charismatic and widely studied vertebrate groups. Black-tufted marmoset is a species of New World monkey, known in Portuguese as Mico-Estrella. They are characterized by black tufts around their ears and usually have some discolored white hair on the face.

Black-tufted marmoset (Clythrix penicillata) is also known as Portuguese micro-estrella. This particular type of species lives mainly in the Neo-Tropical Gallery forests which is situated in the Brazilian Central Highlands. It is located 8 to 25 degrees south of the interior area, from Bahia to Paran। and generally to the city of Rio de Janeiro where it was launched. These marmosets usually live in the rain forest, live higher in the trees but remain under the camp. They are rarely seen near the ground.

Physical Description

The blackened marmosets are marked by black tufts around their ears. It usually has some touching white hair on its face. It usually has a brown or black head, and its limbs and upper body are gray, as well as pale, but its border and lower body are usually black. Its tail is worn with black and white and not prehensile, but used for balance. It has no anti-thumb and its nails have a nail-like appearance. The black marmoset reaches a size of 19 to 22 centimeters and weighs up to 350 grams.

Behavior

The duodenal and arboreal, black-spotted marmosets’ lives are very similar to those of other marmosets. It is usually in the family of 2 to 3 years The groups are usually a breeding couple and their children. Twins are very common in this breed and in men, as well as the offspring of children, often assisting the female in childbirth.

Although black-spotted marmosets live in small families, it is believed that they share their food source, sap plants with other marmoset groups.

Aromatic markings are observed in these groups, but it is believed that marking prevents other species than other Blackfish marmoset groups because other groups generally ignore these markings. These seem to migrate, often continuing with the wet or dry seasons, but the extent of their migration is unknown.

Although communication between black and white marmosets has not been fully studied, it is believed that it communicates through voice. It is known to be predator-specific screams and the predator is often vocalized out of crying.

Food and prophecy

The Krishnachaura Marmoset diet consists primarily of tree sap that nibbles the bark with long bottom incisors. During drought, it will also include fruits and insects in his diet. It is also known to eat small arthropods, mollusks, bird eggs, baby birds and small spines during severe droughts.

Larger birds of prey are the biggest threat to the blackened marmoset, however, and snakes and wild cats also pose a danger to them. Predator-specific voice and visual scanning is its only pre-prediction technique.

Breed

The Krishnachaura Marmoset is in single and family groups. It reproduces twice a year and produces 1 to 4 offspring, though in most cases only twins. Breastfeeding is 150 days and lactation is 8 weeks.

There is a considerable investment of parents by this species, with both parents, as well as older minors helping youngsters grow up.

The offspring are ultimately dependent on their parents and although they are sexually 18 months old, they usually do not have intercourse most of the time, unless they are with their family.

Ecosystems and conservation status

Krishnachaura Marmoset is reciprocal with many species of fruit trees as it distributes seeds from fruits eaten throughout the forest. However, it is a parasite of other species of the tree because it causes a blow to the tree to remove the sap, while giving no apparent benefit to the tree.

Although this marmoset is not the main food source of any particular species, it is a food source for many species, especially predators, wild cats, and huge birds of snakes.

Black-spotted marmosets have been listed on the IUCN Red List or the U.S. Endangered Species Act as having no special status. It is listed in Appendix II to CITES and is not currently considered an endangered or threatened species.

In the state of Rio de Janeiro, where it was introduced along with the common marmoset, it is considered an invasive species that threatens the survival of endangered golden lion tamarins through competition.

The management of invasive habitats of the species includes proposals to promote public awareness to prevent sterilization, migration, and further release of breeding-age individuals.
