A mammal can be a carnivore (meat eater), herbivore (plant eater) or
omnivore (meat and plant eater). By looking at the teeth , eye position and
feet you can usually identify which of the three it is.
First let's look at teeth. If the mammal has long, sharp canine teeth next to the
front ( incisor ) teeth and also has sharp cheek teeth (carnissials) it is a
carnivore . The canines are for seizing and stabbing prey. The carnassials help
cut up meat in the mouth.
If the mammal has either blunt canines or no canines, and has big flat side and
back teeth ( premolars and molars) it is a herbivore. Herbivores use their molars
for crushing and grinding plants.
But what about herbivores that do have large front teeth? Beavers, for example,
have huge front incisors . And river hippos have two huge lower canines . Well,
beavers use their incisors for chewing through bark, branches and even trees. And
hippos use their canine tusks for defense and fighting, not for chewing . But
both beavers and hippos have large flat molars that they use for grinding up plant
matter.
If the mammal has a variety of all kinds of teeth (canines, incisors, premolars and
molars) it is an omnivore . It has a variety of teeth because it eats a variety of
foods, both meat and plants.

ANSWER SHEET
Fur, hair or bristles cover most mammals . Some mammals like elephants, have
very little hair while some have lot like cats or sheep. Sheep's fur is used to make
wool. Porcupines and hedgehogs have needle like spikes on their bodies
instead of hair.
The function of a frog's skin is to regulate the transfer of moisture and fluids.
In colder regions, many birds and mammals develop a special coat on their body
which is very thick and white and protects them from the cold. They shed that coat
during the summer seasons. In very hot areas, animals have lesser hair. Deer,
Zebras, Giraffes etc have very short hair on their skins. Camels that live in deserts
have thick skin with shot hair.
In many cases, an animal skin, fur or hair may match the colour of the surroundings
and protects them from predators . This is called camouflage . Most animals in
the desert area are sand-coloured while in snowy areas they are white.
