Fat-Tailed Dwarf Lemurs

The Fat-Tailed Dwarf Lemur (Cheirogaleus medius), also known as the lesser dwarf lemur, western fat-tailed dwarf lemur, or spiny forest dwarf lemur, is endemic to Madagascar. This species is nocturnal, with a diet of insects, other small animals, fruits, and flowers. The adult lemur mass is 160 grams. There is some C. medius that lives in tropical rain forests, despite the fact that the majority of them are found in dry regions. Research has shown that the length of these creatures' hibernation is related to how they reproduce. These lemurs are more active in the rainforest than they would be in a dry forest.

Recent studies have revealed that C. medius hibernates (or aestivates), despite the fact that temperatures are still high in Madagascar's tropical winter. Hibernation has only ever been proven in one ape and the first tropical mammal. The lemur appears to be evading the drought, despite the fact that the winter in Madagascar is dry. It has a seven-month hibernation period. The lemur does not regulate its body temperature while hibernating, and if the tree hole in which it is sleeping is not properly insulated, its body temperature swings in accordance with the outside temperature. This is in contrast to species that hibernate in temperate climates.
