All lemurs
are considered endangered by the U.S. Fish and Wildlife Service. ·
The name “lemur”
comes from the Latin word lemures, which means “ghosts.” ·
Ruffed lemurs are the only primates that have litters. There
are two subspecies of ruffed
lemurs—black-and-white ruffed lemurs are covered in black and white fur, while
red ruffed lemurs are mostly red, with a black forehead, crown and tail, and a
white patch at the back of the head. Their ears are tufted and their eyes are a
golden colour. Their name comes from the ruff of fur framing their
face.
Ruffed lemurs live
in the eastern rainforests in eastern Madagascar. Ruffed lemurs eat mostly
fruit, as well as nectar, leaves, flowers and sometimes soil. Ruffed lemurs are believed to be
monogamous. Gestation lasts approximately three months and the young are born
from September through November. Although females can give birth to up to six, the
litter size is usually two or three. They are born with their eyes open and
fully furred, but are too weak to cling to their mother, so they are placed in a
nest of branches and leaves, prepared by the mother prior to their birth.
Sometimes females further line their nests with fur plucked from their own
bodies. When the babies are three weeks old, they begin to follow their mothers
around. Ruffed lemurs are social animals that live in groups of two to
16 individuals, with the average size being approximately five. They reinforce their relationships by grooming each other.
Ruffed lemurs are known for their series of loud alarm calls that warn other
members of their group of approaching predators. Forest destruction and hunting are the major conservation
concerns for ruffed lemurs. The red-ruffed lemur is listed as Critically
Endangered by the IUCN. All the
