Lesser iron grey dwarf lemur
Another dwarf lemur with little media available about it, there is no video, and this is the highest resolution image that I found.
Having said this, looking at this information, it is hard to understand how even this image was got. It is known from 1 individual which is in a museum in south central Madagascar.
As of 2010, no studies had been done, and I can see no publicity of a study occurring in the last 14 years either.
There is also no record of this species being held in captivity anywhere in the world. We will look to add any information if we discover any.
