Take the fat-tailed dwarf lemur.

Like bears, bees and many other animals, the fat-tailed dwarf lemur goes into this state of 'suspended animation' for the winter.

Based on the population densities of other dwarf lemur species, Gardner says he "would 'guesstimate' that the total population may be in the hundreds."

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

The dwarf lemurs all belong to one genus, Cheirogaleus.
