Tupaiidaeis one of twofamiliesoftreeshrews,the other family beingPtilocercidae.The family contains three living genera and 19 livingspecies.[1]The family name derives fromtupai,the Malay word for treeshrew and also for squirrel which tupaiids superficially resemble. The formergenusUrogalewas disbanded in 2011 when the Mindanao treeshrew was moved toTupaiabased on a molecular phylogeny.[4]

Unlike shrews, they possess a fairly largebrainfor their size. While some research has found treeshrews as the closest living relative to primates, most molecular studies currently find the flying lemurs (colugos) as the sister group to primates despite their gliding specializations.[5]

Conservation
editA majority of the species, 71.4%, in this family are of least concern, according to the IUCN red list. Nearly a twentieth of the species, 4.8%, are vulnerable and the same number are endangered. 19% of the species have not had enough data collected yet for them to be rated on the scale.[6]
