Unlike other [[marmoset]]s, Wied's Marmoset lives in groups consisting of 4 or 5 females and 2 or 3 males (plus children). They are [[matriarchal]], and only the dominant female is allowed to mate. Like other marmosets, the offspring are always born in pairs. This [[monkey]] supplements its diet of sap with fruit, nectar, flowers and seeds, as well as spiders and insects. Since these are harvested from the middle and lower part of the forest, Wied's Marmoset often travels and forages in the company of the [[Golden-headed Lion Tamarin]], which forages in the canopy. Wied's Marmoset is eaten by [[bird of prey|birds of prey]] (the [[Harpy Eagle]], the [[Gray Hawk]], the [[Roadside Hawk]] and the [[White-tailed Hawk]]), felines (the [[Jaguar]], [[Jaguarundi]] and [[Ocelot]]) and [[snake]]s. Wied's Marmoset is highly social, spending much of its time grooming. It has individually distinctive calls, and it communicates through gestures and olfactory markings as well. The coloring of Wied's Marmoset is mostly black, with white markings on cheeks and forehead. It has rings on its tail and black tufts of fur coming out of its ears. ==Chimerism== It has been proven that a mutual exchange of [[germ cell|germ cells]] often happens between the twins evolving [[in utero]] such producing so called [[chimera (genetics)|chimeras]] - organisms containing two sets of [[cell (biology)|cells]] stemming from two different [[zygote|zygotes]] - [[ovum|ova]] fertilized by two different [[sperm|sperms]] (possibly even produced by two different males). This implies that some [[Tissue (biology)|tissues]] of a Wied's marmoset's body could come from a second ("minor") father.<ref name=chimera>{{cite journal | doi = 10.1073/pnas.0607426104 | author = Ross, C.N., French, J.A., and Ortí, G. | title = Germ-line chimerism and paternal care in marmosets (''Callithrix kuhlii'') | journal = Proc.

The most interesting implication of this fact consists in the possibility that even a sperm or an ovum produced by an individual can stem from its sibling's germ cell - so an offspring of such an individual happens genetically to be its sibling's progeny.<ref name=chimera/> ==References== {{reflist}} ==External links== * [http://animaldiversity.ummz.umich.edu/site/accounts/information/Callithrix_kuhlii.html Animal Diversity Web: Callithrix kuhlii] {{Cebidae nav}} [[Category:New World monkeys]] [[Category:Mammals of South America]] [[Category:Animals described in 1985]] [[ca:Callithrix kuhlii]] [[fr:Callithrix kuhlii]]
