The Danfoss's mouse lemur (Microcebus danfossi), also known as the Ambarijeby mouse lemur, is a tiny mouse lemur. It lives only on the island of Madagascar. These lemurs make their home in the western deciduous forests, between the Sofia River and the Maevarano River.
You can find many of these lemurs in the Ambarijevy, Anjajavy, and Beanamaolo forests. They usually live for about 5 years, but some can live up to 10 years. Mouse lemurs are part of a group called lemuriformes. This group makes up 20% of all primates and over 60% of the mammals found in Madagascar.
Scientists don't know exactly how many Danfoss's mouse lemurs live in the wild or in zoos. However, experts estimate there are about 2 to 5 individuals per hectare. Sadly, their population is shrinking.

Where They Live
Danfoss's mouse lemurs live in dry deciduous forests. Their homes can be found at heights up to 780 meters (about 2,500 feet). Each lemur might use an area from 50 to 400 hectares (about 120 to 1,000 acres).
Their forest home is split into many smaller parts. These lemurs often hide in tree holes during the day. This helps them save energy and stay safe.
What They Eat
Dry deciduous forests don't have a lot of food. Still, mouse lemurs eat many different things. Their diet includes insects, spiders, small vertebrates (like tiny lizards), fruits, and flowers.
Danfoss's mouse lemurs especially love bananas. Researchers often use bananas to help catch them for studies.
How They Look
Microcebus danfossi belongs to the group of the smallest primates on Earth. But compared to other mouse lemurs, the Danfoss's mouse lemur is quite large. It is a reddish lemur, measuring 25 to 29 centimeters (about 10 to 11 inches) long. This includes its tail, which is 15 to 17 centimeters (about 6 to 7 inches) long.
The Danfoss's mouse lemur has short, thick fur. It also has a white stripe that runs between its eyes. These lemurs look similar to other mouse lemur species. However, each species has unique genetic differences. Their bodies are also very good at saving energy and water. They can change their body temperature to match the air around them.
Reproduction and Life Cycle
Danfoss's mouse lemurs can have babies for a long time each year. Their breeding season can last from May to October, and sometimes even November. This is longer than many other lemur species. Their habitat is near a humid forest, which means more food is available for them.
They usually start having babies around one year old. Pregnancy lasts about 60 days. Most female lemurs give birth every year. This means a new generation of Danfoss's mouse lemurs appears every 1 to 5 years.
Behavior
Social Life
Microcebus danfossi lemurs look for food alone at night. They live in groups that are spread out. However, they often sleep together in regular groups. These sleeping groups might be:
- Only related females.
- Related males and females.
- Sometimes, a lemur sleeps alone.
Most female lemurs only interact with other females from their own sleeping group. They try to avoid females from nearby groups. Male sleeping groups seem to be less tolerant of each other. Most sleeping groups are led by females. Danfoss's mouse lemurs use sounds and smells to communicate and form these groups. They often use their feces and urine to mark their territory.
Taking Care of Babies
Baby lemurs drink their mother's milk for several weeks. The mother provides most of the care during this time. However, some male lemurs have been seen grooming, carrying, and guarding the babies.
Because the babies stop drinking milk so quickly, they have little time to learn social skills. To help the mother find food, they use a system called "infant parking." This means the mother leaves her baby or babies in their nest or tree hole while she goes out to find food.
Threats to Their Survival
Danfoss's mouse lemurs face many dangers. Their main predators are:
- Birds of prey: Like owls, hawks, and eagles.
- Snakes: Such as boas.
- Carnivores: Including mongooses and fossas.
- Introduced animals: Like dogs and cats.
Mouse lemurs have the highest rates of being hunted among all primates. This is mainly because of their small size.
However, the biggest threat to these lemurs today comes from humans. About 90% of Madagascar's original forests have already been destroyed. This includes the dry deciduous forests where Danfoss's mouse lemurs live. This loss of habitat is mostly due to farming and grazing animals. These lemurs are also sometimes hunted for the exotic pet trade.
Protecting Them
Human activities, especially farming, are the main reason for habitat loss. This has caused the forests to become broken into small pieces. This is a big problem for conservation. It traps lemurs in small groups, which reduces their genetic diversity. This means they can only have babies with a small number of other lemurs.
Scientists believe their population started to drop about 85 to 100 years ago. Around 11,000 lemurs may have disappeared since then. Studies show that these population drops happened around the same time humans started settling in Madagascar.
Conservation Status
The IUCN (International Union for Conservation of Nature) currently lists the Danfoss's mouse lemur as Vulnerable since 2018. Before that, in 2014, it was considered Endangered. It is hard for conservation groups to help this species. This is because their habitat is difficult to reach, and not much is known about them.
The IUCN is very clear about how serious the situation is. They predict that if no action is taken, all of the Danfoss's mouse lemur habitat could be gone by 2080 due to climate change alone. Without a suitable home, the species is unlikely to survive much longer. Given their current status and the speed at which their numbers are falling, they might even become extinct sooner. This is because human activity, not just climate change, is their biggest threat.
Most organizations agree that current efforts are not enough. These efforts include international laws and controls on trade. Also, only one small part of their forest, called Bora, is a protected area.
