Red Ruffed Lemur

 


Classification:
Order Primates
Family Lemuridae
Varencia variegata rubra

Conservation Status:
Endangered under Red List-  CITES Appendix 1

 

Description:
The Red Ruffed Lemur can grow to be 3.5 feet long from its head to the end of its tail.  The tail alone can account for almost 2 feet of this total length and is used for balance when jumping from branch to branch through the trees.  They are the largest member of the Lemuridae family and are called “ruffed” lemurs due to the tufts of long, thick fur on their ears.  They have soft fur that is mostly reddish-brown in color with a black face, feet, tail, and belly.  They can weigh anywhere between 7-10 lbs.  

Range:
Island of Madagascar

Habitat:
Rainforest

Diet:
Red ruffed lemurs are completely herbivorous and have a diet consisting of fruits, nectar, seeds, leaves, and flowers.

Life Cycle:
The breeding season occurs from May through July in the wild, with the female in estrus for only a few days during this time, and only fertile one day during estrus.  After a gestation period of 90-102 days, the female will produce a litter of 2-6 newborns, with 2-3 being the average.  Ruffed lemurs are the only primate that can produce a litter of offspring instead of only a single newborn or twins.  When born, the Red Ruffed Lemur will have its eyes open and be fully furred, but will not have enough strength to cling to its mother.  Because of this, the mother will pick the newborn up and place it in a nest of branches and leaves that she constructed prior to the birth.  The mother may construct several of these nests and move the developing young around to various locations while she is foraging.  By the time the young reach 7 weeks of age, they are capable of following the mother around the treetops.  Weaning occurs around 4 months, and sexual maturity is reached at about 2 years, but the females do not reproduce until they are about 3 years of age.

Did You Know?

·     Instead of using their hands to groom parasites from their fur, red ruffed lemurs use a special set of teeth called a "toothcomb"

·        The red ruffed lemur has a complex social system with females always having a higher social status than males.

·       These lemurs have a very loud warning system.  When a predator is nearby, they use an elaborate series of barks and calls to alert other lemurs in the area to the threat.  These newly alerted lemurs will then take up the warning call until all those in the area are aware of the danger. 

·        Red Ruffed Lemurs have an excellent sense of smell and rely heavily on scent as a way to identify group members and mark territories.  They have scent glands located on their wrists and on their bottoms that aid in this process.
