Silky sifaka (Propithecus candidus) is a species of lemur only found in a restricted range of northeastern Madagascar. In that region of Madagascar, the silky sifaka is known locally as simpona. Silky sifaka is a large lemur with long and silky white-colored fur. Due to various reasons like habitat loss and hunting at an alarming rate, these Endangered primates are considered one of the rarest species in the world. Silky sifakas are found in some protected areas and rainforests in the region with the majority of the population in the Marojejy National Park and Anjanaharibe-Sud Special Reserve. The population of the silky sifakas has reduced so much that only a few group members have been documented in recent times. There is no local taboo for hunting and eating these animals, which has led to a decline in the population of the silky sifakas.

Silky sifakas are known for their scent-marking behaviors where males scent mark trees by rubbing the trees with their chest gland, genital glands, or both. Females are known to do it by rubbing the genital glands in a vertical motion. The mating includes females giving birth to one young every two years or so.

The majority of the feeding of these primates consists of leaves and seeds, like all eastern sifakas. During feeding, females take priority over males. The social structure of the silky sifaka is variable and groups are formed between males and females with male-female pairs, one-male groups, and multi-male or multi-female groups.

Silky Sifaka Interesting Facts

What type of animal is a silky sifaka?

Silky sifaka is a species of large lemur found only in Madagascar.

What class of animal does a silky sifaka belong to?

Silky sifaka (Propithecus candidus) belongs to the class of Mammalia in the kingdom of Animalia.

How many silky sifakas are there in the world?

The population size of the lemurs known as silky sifakas is known to be just 100-1,000 individuals. Groups and members of mature males and females are calculated only to be around 250 individuals currently. Habitat disturbance and hunting of these lemurs have led to this decline in the population of the species and conservation practices to save the lemurs have all failed for now.

The silky sifaka has been observed in only a few places in Madagascar. The animal is observed in some protected areas of the region.

Where does a silky sifaka live?

The distribution range of the silky sifakas is restricted to the range of northwestern Madagascar. The range extends from Maroantsetra to the Andapa Basin. Group members are also found in Antainambalana River in the south and Maraojejy National Park to the north. Apart from this range, they also have been seen in far north areas of the Bemarivo River near Sambava. The range of the lemurs is restricted on the northwest side of Madagascar by the Androranga River in the Tsaratanana Corridor. The search for the species is limited to these areas. Apart from these, a group of the species with long, silky white fur is scattered on the trees of the restricted areas of Marojeju and Anjanaharibe.

Most of the silky sifakas are now found in the elevated areas of the Marojejy National Park and Anjanaharibe-Sud Special Reserve. They are found in areas of height from 2300-6152 ft (701.04-1875.13 m).

What is a silky sifaka's habitat?

The silky sifaka habitat consists of montane and mid-altitude rainforest. The sifakas are more common in rainy areas. The species inhabit high elevations which include sclerophyllous forest and low ericoid bush. As the species is arboreal, the search for the group can be focused on the trees of these rainforests.

The ecology of silky sifaka consists of tropical moist montane forests where it is seen feeding on over 100 different species of tree, vine, and epiphytic/parasitic plants. The animal is seed feeding mostly on the leaves and seeds of the trees.

The population of the Propithecus candidus is quite restricted and only a few are left in the world.

Who do silky sifakas live with?

The social structure of the lemur silky sifaka is unique. The social structure of the lemur species includes groups of male-female pairs, one-male groups, and multi-male or multi-female groups.

How long does a silky sifaka live?

The lifespan of the silky sifaka is not known, and this species cannot survive in captivity. The Verreaux's sifaka is known to live for around 23 years of age. The lifespan of the group silky sifaka should be similar to this species.

How do they reproduce?

It is not known if the silky sifakas remain in the same pair for a lifetime or just during the mating period. Mating is done in a few days from November to January every year. A single infant is born in June/July. Usually, females give birth every two years. Maternal care is huge in this species and the social behavior shown by the infants in clinging to the mother's belly is common to all sifakas.

What is their conservation status?

The population of the Propithecus candidus is decreasing at an alarming rate. The silky sifaka conservation status has been categorized as Critically Endangered by the IUCN Red List. Habitat loss and hunting are the main causes of this status. Also, in Madagascar, it is not illegal to kill and eat these animals. Habitat disturbance like slash-and-burn agriculture, illegal logging of precious woods, and fuelwood has also added to the problems for the silky sifaka.

This rare species can only be seen most in the Marojejy National Park and Anjanaharibe-Sud Special Reserve in Madagascar. For proper conservation, education and awareness should be provided to all people involved in the area.
