• Animals belonging to
the kingdom animalia
are multicellular,
eukaryotic heterotrophs
whose cells lack cell
walls.
INVERTEBRATES
• These are animals that have no
backbone or vertebral column.
• They range in size from
microscopic dust mites to more
than 20 meters in length.
• They include groups as diverse
as sea stars, worms, jellyfish and
insects.
VERTEBRATES
• Vertebrates are those
animals having
backbone.
• They comprise the 5%
of the animals in the
animal kingdom.
• These animals include
fishes, amphibians,
reptiles, birds and
mammals.
1.FEEDING
Animals feed in
various ways.
Herbivores feed on
plants including
roots, stems,
flowers and fruits.
They are also called
as plant-eaters.
• CARNIVORES • OMNIVORES
are those animals
that feed on
other animals.
• They are also
called as animal
eaters.
are animals that
feed on both
plants and
animals.
2. RESPIRATION
All animals
whether they
live in water or
on land undergo
respiration. This
means that they
take in oxygen
and release
carbon dioxide.
3. CIRCULATION
Large animals have
circulatory system
that made possible
for the circulation of
nutrients to take
place.
Smaller animals
such as small
aquatic worms rely
on diffusion for the
circulation of
important nutrients.

6. MOVEMENT
Complex animals tend to have
high levels of cell
specialization and internal
body organization, bilateral
body symmetry, a front end
or head with sense organs
and a body cavity.
