So far we know almost nothing about the new dwarf lemurs.

The dwarf lemurs all belong to one genus, Cheirogaleus.

For the seven months of the dry season, fat-tailed dwarf lemurs hibernate, curled up in tree holes.

They are active at night and they eat fruit, like all dwarf lemurs, but that is about it.

Whether they are a new species or not, the dwarf lemurs of Nosy Hara are in a precarious situation.

Primatologist Charlie Gardner went on holiday and found a new population of dwarf lemurs, which might even be a new species.

Dwarf lemurs are the only primates that hibernate, and this may be what allows the Nosy Hara population to keep going.
