Pygmy Mouse Lemur: A Tiny Wonder of the Forest

Let’s meet pygmy mouse lemur – the smallest lemur of all. Even though they’re small, the fascinating creatures from Madagascar have some amazing features and interesting habits. In this article, we’ll explore their hidden world, discovering how they survive, their social lives, their adaptions, and the important roles they play in the environment. Here are some interesting facts about this species.

Scientific name: Microcebus myoxinus
Phylum: Chordata
Class: Mammalia
Order: Primates
Family: Cheirogaleidae
Genus: Microcebus

They’re small and cute

​The pygmy mouse lemur is known by various names, such as dormouse lemur or Peters’ mouse lemur. It is one of the cutest lemur species in the world. These tiny primates are super small, about 2.4 inches (6.1 cm) from head to body. They have a tail that is two times longer than their body and head combined. The animals weigh a mere 1.1 ounces (30.6 g), females tend to be heavier than males, except for the mating season. With this size, they are the world’s smallest primates.

Even though pygmy mouse lemurs are small, they have unique physical features. They have short, pointed snouts, big expressive eyes, and incredibly movable, large ears that make them look cute.

The pygmy mouse lemur appearance

Typically, their fur takes on a reddish-brown hue, with some variations such as a black stripe along the spine and an additional white stripe running vertically between their nose and eyes. The underbelly of these lemurs has a creamy color.

The sole distinction between males and females lies in the length of their ears. Males exhibit slightly longer ears, possibly contributing to improved communication during the mating season. Their limbs are relatively abbreviated, with the forelegs slightly shorter than the hindlegs. Additionally, their hands look like petite, frog-like structures featuring broad pads on the fingertips.


Pygmy mouse lemurs live in Madagascar. Their range extends across a disjunct area, stretching from the northern banks of the Tsiribihina River to Baie de Baly National Park. These lemurs are primarily found in the dry deciduous woodlands of western Madagascar and sometimes occur in secondary forests. Additionally, they have been observed in coastal mangrove forests.

Pygmy mouse lemur Diet

Pygmy mouse lemurs are primarily omnivores, with the majority of their diet consisting of fruits. These diminutive creatures diversify their palate by incorporating gums, flowers, and occasionally small insects into their meals. This adaptable dietary behavior enables them to adapt to fluctuations in food availability across different seasons.

The pygmy mouse lemur lives on trees

However, leaves are the type of food they will try to avoid. This is because many many plants in their dry habitat emit toxins as a protective measure against herbivores that consume leaves. Due to their diminutive size, even minimal exposure to these toxins could prove fatal for this mouse lemur.

Being small means there are more threats. These nocturnal lemurs become easy targets for larger predators like mammals and birds, especially owls.

They live a solitary life

Pygmy mouse lemurs, similar to their fellow mouse lemur species, live a nocturnal life. They spend their nights moving between the trees, using their small bodies to swing and jump. In the daytime, they seek cool, dry shelters in tree hollows or among branches.

Similar to hibernating bears, these lemurs handle dry seasons by going into a kind of deep sleep every day for about 9 hours. During this time, their bodies become super efficient, slowing down their metabolism by a whopping 90% and lowering their body temperature almost to the level of their surroundings.

This incredible skill helps them save energy and get through periods when food is scarce. However, not all of them do this. Even in the same group, some lemurs opt to go into this deep sleep mode, while others stay active.

These species prefer to be alone, although males sometimes team up temporarily while traveling. Unlike many other primates, they don’t like to live in big groups and prefer staying in their own space. This helps them avoid predators and reduces competition for safe sleeping spots, which are important for raising their young. The males have larger territories than the females.

Not much is known about how pygmy mouse lemur communicate. It’s believed they might make sounds like whistles, purrs, and chitters.


Pygmy mouse lemurs are polygynandrous, which means they mate with multiple partners. Their mating season spans from November to December through May to June, with the primary period of estrus occurring between November and December.

In this phase, the male experiences an increase in weight attributed to the enlargement of its testes. Rather than defending a particular territory, he actively moves around to optimize his chances of encountering receptive females. His territories are distributed across a broader range and often overlap.

After mating, the male inserts a sperm plug into the female’s body to prevent her mating with other males. This helps the male increase his chances of being the father of the offspring. The female goes through a gestation period of about 50 to 62 days. She will give birth to 1 – 2 offspring. These young will wean and become independents after approximately 60 days. The lifespan of pygmy mouse lemur in the wild is about 6 – 8 years.

They are endangered species

Peters’s mouse lemurs actively contribute to the flourishing ecotourism sector in western Madagascar. Besides their economic significance, these lemurs also eat fruit, spreading seeds and helping fruit trees grow for people to eat.

But, these lemurs are in danger. Their population has gone down by more than 30% in the last 15 years, and they are now at risk. They are listed as Vulnerable species in the IUCN Red List. The primary reason behind this decline is the loss and degradation of their habitat, stemming from unsustainable agricultural practices. This has caused their living spaces to break apart. Sadly, this problem isn’t just for pygmy mouse lemurs. Over 250,000 different kinds of animals in Madagascar are facing the same issue.
