Indri indri (Gmelin, 1788)

Indri (Indri indri) on Madagaskarin metsissä elävä, suurin jäljellä oleva puoliapina. Se on sukunsa Indri ainoa laji. Indri tunnetaan laulustaan. Kansainvälinen luonnonsuojeluliitto IUCN on määritellyt sen äärimmäisen uhanalaiseksi lajiksi. Kannan kokoa ei tunneta varmuudella, mutta joidenkin arvioiden mukaan indrejä on vain 1 000–10 000.
