Description

The fur of the Common Marmoset is grey. The most distinguishing characteristic is the white tufts of hair which surround the ears, which lend it another common name, the Cotton Eared Marmoset. A white mark is on the forehead and the face is hairless. The long tail is grey-white. Common Marmoset adult size ranges from 14 to 18 cm and they weigh approximately 400 g or 14ounces

Habitat

Like all callitrichines, Common Marmosets are diurnal. The Callitrichinae (synonym Hapalinae are a subfamily within the family Cebidae, one of the four families of New World monkeys. In Animal behavior, diurnality indicates an Animal that is active during the Daytime and rests during the Night. Their habitat ranges from the edge of forests into the deep forests, but they also appear in fields. They can run swiftly along the branches of trees and are also excellent jumpers.

Diet

The diet of the Common Marmoset consists of insects, spiders, small vertebrates, bird eggs and tree sap. Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Spiders are Predatory Invertebrate Animals that have two body segments, eight legs no chewing mouth parts and no wings Vertebrates are members of the Subphylum Vertebrata, Chordates with backbones or spinal columns The grouping sometimes includes In most Birds and Reptiles an egg ( Latin ovum) is the Zygote, resulting from Fertilization of the Ovum. They spend 25-30% of their time budget searching for food.

Behavior and reproduction

Common Marmosets live together in family groups of four to 15 animals, usually mated adults and their offspring. These groups inhabit territories of 300,000 square metres. The groups have a strict ranking, ordered by the dominance and aggressive behavior of the group leader.

Common Marmosets have variable mating systems: monogamous, polygynous and polyandrous. All adults and subadults share in the care of the young. After an approximately 150-day gestation, the female typically gives birth to twins, though up to four offspring have been observed in captive settings (larger litters suffer higher mortality rates). Compared to adults, the young animals are very large. Newborn twins together are 20 percent to 27 percent of the body weight of the mother, and it is assumed that the cooperative care of young helps counter some of the high costs of raising twin offspring. Males can mate after about one year, while females aren't fully mature until about 20 to 24 months.

Lifespan

The life expectancy of the Common Marmosets in the wild is about 10 years, although some living in captivity have lived to 16 years.
