The best way to look for any nocturnal lemur was to scan the trees with a torch and look out for eye shine. Mouse lemurs turned out to be everywhere and you would see these two little red eyes, almost demonic, of the lemur looking back at you in the beam of your torch light.
The photo below shows a Fat Tailed Dwarf Lemur high up in the trees. Dwarf lemurs are the only primates to hibernate. This extraordinary characteristic has made them the subject of study by Duke University. The research is looking at how a these lemurs can slow down their vital organs in the hope it can be beneficial in space travel as well as emergency wards.
