Red-Ruffed Lemurs at the Bronx Zoo. Perf. Red Ruffed Lemurs. Youtube. N.p., n.d. Web. < Lemurs usually have a prominent snout that is narrow and fox-like.
They have small ears that are hidden by hair.
While most of their body is a deep red, their hands, feet, forehead, crown, stomach and tail are all black. They also have a white patch of fur on the nape of their neck and might have more white patches in other places too!
They have six bottom incisors. Sizes
They are around 43 to 57 cm (16.9 to 22.4 in).
Its tail is longer than its entire body! Around 56-65 cm (22-25 in)!
There arms and legs are about the same length (this helps them climb!) Adaptations Their long tails help them balance.
They are very uncoordinated so they have long claws on their second toes to help them groom themselves (and others), and there six bottom incisors act as a 'toothcomb' to also groom themselves.
Long, opposable thumbs and fingers/toes on hands and feet help grasp things such as trees and branches. The most common types of movement are quadrupedalism, leaping, clinging, and suspension. They sometime use bipedalism, too. When they are walking, their head is usually facing down while their tail is up high. They usually leap when they are moving between trees and will look over their shoulders while clinging, push off, and then twist in the air. Red Ruffed lemurs are more arboreal and they like tall primary rainforests. These lemurs are only found in a small
north-eastern part of Madagascar.There's only about 30,000 - 50,000 Individual left in the world! Varecia rubra Lifestyles The IUCN Red List labels these primates as endangered.
The main reasons these animals are endangered are because habitat destruction, hunting. These lemurs also have an apparent need for tall primary forest which also makes it hard for them to find a place to say. Fruit make up 75% of a Lemur's diet, but they also eat many different species of plants! During the dry seasons though, they occasionally feed on some leaves and seeds, too. Arboreal vs. Terrestrial Endangerment Habitat (cont.) Activity/Movement Study I got to the chance to observe a Red Ruffed Lemur at the Singapore zoo for 15 minutes. This was a nice opportunity, but the entire time I was there my lemur was just resting and laying down the entire time! The picture to the right is how these lemurs usually spend there time. I think that reason I didn't really get the chance to observe my focal animal being very active is because there were only two of these lemurs at the zoo and these primates spend more than half of their time resting! Red Ruffed Lemurs are also most active in the morning and evenings, and we went in the afternoon to observe them. Lifestyles (cont.) That's it right there at the zoo! Lifespan (wild): 15 - 20 years
Lifespan (captivity): as long as an estimated 36 years.
Age of sexual maturity: 2 years (average)
Breeding interval: Once a year
Breeding season: May to July
Number of offspring: 2 to 6, avg. 3 Life Development and Breeding Social Behavior Red Ruffed Lemurs live in troops. The live in a group of males and females together, with one dominant female that leads the group. A troop of Lemurs usually has between 2 and 16 lemurs, but they can be as large as 30 lemurs.
Male and female lemurs look almost identical, but the females are a bit larger. They are also Diurnal, not nocturnal. they are most active during the mornings and evenings. Red Ruffed Lemurs have at least 12 different vocalizations that they use as a method of communication. They also communicate using scent marking. Diet Since Humans came to Madagascar, 15 species of lemurs have gone extinct! I am really wondering about what people are trying to do to prevent these lemurs from going extinct. Already 15 species of Lemurs have gone extinct since humans came to Madagascar! What were people doing differently? What have they changed? Does it look like these Red Ruffed Lemurs will also become extinct soon?
I am also wondering how long these Red Ruffed lemurs have been around or. There must have been one point in time when all lemur's looked alike, so when did the Red Ruffed Lemurs come around?
My last question is how many species of Lemurs are there known to be left, and are there more Red Ruffed Lemurs than the rest?? And when did the last species of Lemur's to go extinct, go extinct? Was it very recent? Does that mean that there is a very likely chance of the red Ruffed Lemur's going extinct too? Here's a sketch I drew Enclosure
