Lesser iron-gray dwarf lemur

The lesser iron-gray dwarf lemur, also called the large iron-gray dwarf lemur, is a small nocturnal lemur endemic to Madagascar. It is an arboreal quadruped and is not very agile. It makes three kinds of call: a high squeak with the mouth closed used between infants and their mothers, a whistle that is probably communicative or territorial, and a powerful series of grunts given when an animal is attacked in its nest. The species is known from a single museum specimen collected at Ambositra in east-central Madagascar, and as of 2010 no wild study had been made, so it is unknown whether it still survives there.
