Indri Facts You’ll Never Forget

One of the best indri facts is that the indri lemur, also called the babakoto, is not only one of the largest living lemurs but is also one of the most surreal-looking ones.

The indri is a species of lemurs that are also known as babakotos. These are the largest lemurs on the planet with an average lifespan of 15-18 years but they sadly don't survive as long when kept in captivity.

This black and white lemur is famous for its teddy bear-like appearance. Populations of indri are mainly arboreal and completely depend on trees for food. They eat leaves, flowers, seeds, and fruits and are herbivores. Indris are territorial animals that live in protected areas, which are described as their territory. Reproduction in these mammals is sexual, with a female giving birth to offspring every two to three years after a gestation period of several months. These animals are not nocturnal and are awake in the daytime, but these animals are super lazy and spend about 16 hours a day sleeping. The indri species of lemur lives in small groups with five to six others.

This lemur got its name from people of the Betsimisaraka tribe and the name 'babakoto' also originated from this same tribe. If you like reading these indri facts, you can check out more facts on the Bornean orangutan or the capuchin monkey.

What class of animal does an indri belong to?

The indri lemur belongs to the class of mammals as they give birth to their offspring.

How many indris are there in the world?

The current conservation status of indris is Critically Endangered and there has been a drastic decline in the indri lemur's population in the past years. This is due to various natural and human reasons, including slash and burn agriculture. It is estimated that there are 10,000 indris left in the world.

Where does an indri live?

Indris are found in coastal and montane rainforests from the Mangoro River to Sambava. Indris are island animals and are found on the island of Madagascar. They live in groups in the trees and are arboreal. This means that the diet of Indris is strictly vegetarian, and they depend on trees for food. Indris can also live in captivity but normally not for more than a year.

What is an indri's habitat?

Indris are dependent on forests and trees for food and survival, these arboreal indris are found in coastal and montane rainforests on the island of Madagascar. The island is rich in vegetation that supports the diet of indris, who are completely vegetarian and depend on trees for food. Indris eat fruits, leaves, and flowers from trees in order to survive.

Who does an indri live with?

Indris live in small groups of two to six indris, consisting of a mated male, a female, and their offspring. They may even live in bigger groups with several generations of indris in fragmented forests.

How long does an indri live?

In their natural habitat or the wild, they can live for 15 to 18 years. They do not tend to survive in captivity and it is generally agreed that indris cannot survive for more than a year in captivity. The diet of indris is nuanced as they eat foods at different times of day, which cannot always happen in captivity, and that is why they can live much longer (up to 18 years) in the wild.

How do they reproduce?

They live in groups that include at least one mating pair. These male and female indris breed seasonally using sexual reproduction. Indri lemurs reach sexual maturity when they are between seven and nine years old and every two to three years, a female gives birth to offspring. Birth occurs after a gestation period of 120-150 days.

What is their conservation status?

The current conservation status of indri lemurs is Critically Endangered. The main reasons that indris are an endangered species are their loss of habitat and destruction of habitat as a result of local agricultural developments. With drastic declines in the indri lemur's population, there are only 10,000 indris (Indri indri) left in the world.
