ALI HASSAN VIRK
DIFFERENCE BETWEEN SNAKES AND LIZARDS
LIZARD
Lizard refers to a
reptile that typically
has a long body and
tail, four legs, movable
eyelids, and a rough,
scaly, or spiny skin
SNAKES
Snake refers to a long
limbless reptile which
has a short tail, and
jaws that are capable
of considerable
extension.
LIZARD
Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Superorder: Lepidosauria
Order: Squamata
Brief Description
Most lizards are quadrupedal,
running with a strong side-to-
side motion. Others are
legless, and have long snake-
like bodies.
Some such as the
forestdwelling Draco lizards
are able to glide.
They are often territorial, the
males fighting off other males
and signalling, often with
brightly colours, to attract
mates and to intimidate rivals.
Lizards are mainly
carnivorous, often being sit-
and-wait predators; many
smaller species eat insects,
while the Komodo eats
mammals as big as water
buffalo.

Major
Differences
LOCOMOTION
Lizards have legs and snakes
do not have legs. While lizards
move on four limbs, a snake
moves by undulating its body
and also with the help of its
ventral scales. The ventral
scales give the snakes a good
grip on the surface.
Sense of
hearing
Lizards can hear sounds through
their external ear openings. On
the other hand, snakes only hear
through the skull bone. The
snakes, which have no external
ears, hear only through
vibrations from the ground.
