As a unique species endemic to the island of Madagascar and the nearby islands, they are some of the strangest-looking primates alive today for their large eyes, bushy tails, and idiosyncratic behaviour that makes them a prized possession of the island. They are often referred to as “living fossils” due to their resemblance with early primates that existed millions of years ago. They are the most interesting primate of Madagascar.
Amazing facts:
- Tree huggers: Most species of them are arboreal, meaning they live in the trees.
- Omnivorous diet: eating flowers, fruits, and leaves along with a few insects.
- Astounding fact: All nocturnals have enlarged eyes to assist them in lowlight settings.
- Nocturnal and Diurnal: Best of all, Various species have evolved to be active both day and night.
- Long Lifespan: Some species have a longer lifespan of 30 years in captivity.
- Social Creatures: They have social groups called troops, and some species consist of 30 individuals.
- Scent Communication: Scent glands are one of the main methods of conveying messages and marking a region or territory.
- Critically Endangered: Most of their species are critically endangered because of the loss of their habitats.
Habitat and Food:
