Lemurs - a special class of primates
Now that you've learned much about our closest relatives and animal
friends, the chimpanzees, gorillas and orangutans, over the past few
weeks, today we will feature yet another kind of primate related to the
apes and us...

Red-ruffed lemur.

Have you heard of a kind of primate called lemurs, sometimes known as
the greater mouse? Even if you have heard of them or seen pictures of
these creatures, you may have never connected them to primates, because
of their appearance.
Lemurs are a special class of primates known as prosimiants found
only in Madagascar, (the world's fourth largest island), which is
226,650 square miles in size, and the Comoro Islands. Most of you must
be aware of the location of Madagascar, in the Indian Ocean, 250 miles
off the Southeastern coast of Africa. The Comoro Islands are situated in
the North of Madagascar.
It is believed that more than 40 million years ago, some of the
ancestors of modern lemurs were carried out to sea on islands of
floating vegetation, and ended up on the island of Madagascar. As time
passed, these animals evolved into many different species, ranging from
the size of a mouse, to the size of a St. Bernard dog.

Today, there are 14 genera of lemurs. There are 50 species of lemurs,
and out of these, about 17 are on the endangered species list. The name
lemur is derived from the Latin word lemures, which means 'spirits of
the night'. This may have been given due to the large, reflective eyes
of the nocturnal species.
Ring-tailed lemurs
This type of lemurs are easy to recognize because of their long,
black and white striped tails and the black mask patterns on their white
faces. Their fur is a solid brownish grey on the back. Their bellies
however are white. An adult lemur is no bigger than a cat.

As ring-tailed lemurs are partly arboreal and partly terrestrial,
they spend more time on the ground hunting for food, which consists
mainly of fruits and some leaves, and occasionally insects.
Ring-tailed lemurs live in groups of 5-25 animals in which the adult
females are dominant over the males. Females stay in the group into
which they are born, but the males move away.

Their food and their babies...

Some lemurs are omnivores and some are herbivores. They eat fruits,
flowers, leaves, insects, spiders and small vertebrate.
Baby lemurs are born during early spring, that's around September in
Madagascar. Once mama lemur gives birth to a single baby, she takes good
care of it. Baby lemur travels about clinging to its mother's belly
during the first two weeks of life. Then, when it becomes a little too
big to do this, it jumps on to her back and gets about, until it becomes
too large to do even this.

What lemurs look like

Even though there are many kinds of lemurs, most have long, pointed
noses, which contribute to their excellent sense of smell, coats that
vary from reddish brown colour to grey, long limbs, flexible toes and
fingers.
They come in all different sizes. The Pygmy Mouse lemur, which is the
smallest, weighs only an ounce, but the biggest ones, the Indri and
Diademed Sifaka lemurs can weigh up to 15 pounds, which is about the
size of a big cat. They have big, bushy tails which they often wrap
around their own bodies or that of a neighbour's, when they are at rest.

Species under threat

The lemurs are faced with the threat of extinction on different
levels. Some lemurs, such as the Red-ruffed lemur and certain types of
Bamboo lemurs are considered to be in the 'Critically endangered' list.
In the list of 'Endangered' lemurs, Hairy-eared dwarf lemur, the Golden
brown mouse lemur and the Black and white ruffed lemur are included.

The Black lemur, Crowned lemur and a number of Fork-marked lemurs are
all on the 'Vulnerable' list, while the Avahi, the Lesser Bamboo lemur
and a number of supportive lemurs are classed in the 'Lower risk'
category as they have the best chance of survival in the wilds.

Why they are threatened...

The loss of habitat due to large-scale deforestation for the purpose
of agriculture, timber production and other purposes is the main cause
for the depletion of the lemur population in Madagascar and Comoro
Islands.
The lemurs are also hunted for food and also out of fear the people
have for these strange creatures, especially the Aye-aye.

Madagascar is not a rich country, and most people cannot think of
conservation when they are struggling to put food on the table to feed
their families. However, measures have been taken to make the people
aware as to why they should protect not only the endangered species of
lemurs, but all other remaining life forms in the rich rainforests of
Madagascar.

Already, parts of the rainforest have been set aside and have become
protected areas for a large number of unique plants, and animals that
call it home.

Their habits and habitat
Most lemurs are arboreal, which means that they spend a major part of
their time on trees and bushes. They have a good grip to hang on to
branches. Their long tails help them to maintain their balance when they
leap from tree to tree. The Ringtail lemur does not spend as much time
on trees as its cousins, because it prefers to run about on the ground,
most of the time.

Lemurs that are awake and active during the day live in groups, but
nocturnal lemurs tend to live alone. In general, lemurs are social
animals.
The lemurs which are found only in Madagascar and neighbouring Comoro
Islands live in a variety of habitats ranging from moist, tropical
rainforests to dry desert areas.

Communication methods
Since lemurs, with their long noses, have an excellent sense of
smell, they use their sense of smell to 'talk' to each other. Now, if
you are puzzled as to how they use their noses to talk, let's check it
out.

Lemurs have scent glands on their bottoms and on their feet. These
help them to leave out odours on whatever surfaces they cross. So, when
another lemur goes by that route, it enables the lemur to know that a
lemur has passed that way. Lemurs also use their tails to communicate.
They wave the tails in the air when they want to get their message
across to another lemur. They also make noises to communicate. |
