DIFFERENCE BETWEEN SNAKES AND LIZARD ,BEST PRESENTATION PREPARED BY ALI HASSAN ,THIS WILL BE REALLY HELPFUL SPECIALLY FOR SCIENCE STUDENTS (ZOOLOGY ,BIOLOGY STUDENTS)
2. 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.
4. 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.
25. Brief
Description
• A long limbless reptile which has no
• eyelids, a short tail, and jaws that are
• capable of considerable extension.
• Most snakes have a venomous bite.
• Snakes are elongated, legless,
• carnivorous reptiles of the suborder
• Serpentes.
26. TYPES OF SNAKES:
• • Snake Species.
• • King Cobra.
• • American Copperhead.
• • Black Mamba.
• • Corn Snake.
• • Rattlesnake.
• • Boa Constrictor.
• • Eastern Coral Snake.
• • Black Rat Snake.
• • Burmese Python
27. 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.
28. Summarization of the differences
• 1. Lizards have legs and snakes
• do not have legs.
• 2. While lizards move on four
• limbs, a snake moves by
• undulating its body and also
• with the help of its ventral
• scales.
• 3. 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
29. Summarization of the differences
• only through vibrations from
• the ground.
• 4. While lizards can close their
• eyes, snakes cannot close their
• eyes.
• 5. Lizards have two moveable
• eyelids, but a transparent scale is
• what covers the eye of a snake.
• 6. A lizard sheds its tail when
• agitated or in times of danger,
• but snakes shed their skin.
• 7. While a lizard comes with
• two lungs, a snake has only one
• lung that works.
