Characteristics
Of Animals
The Animal Kingdom
Characteristics of Animals
• They are multicellular.
• They reproduce either sexually or
asexually.
• They have distinct body parts that
do different things.
• They can move around.
• They cannot make their own food.

Animal Kingdom
• Animals are classified
into the Animal
Kingdom.
• Animals are
consumers.
• Animals can be
grouped as
Invertebrates or
vertebrates.
Invertebrate -No
backbone
Vertebrates Backbone present
Vertebrates can be further characterized as endotherms
or ectotherms.
• Endotherms-Animal that can
produce its own heat and can
maintain a constant body
temperature.
• Ectotherms-an organism that
needs sources of heat outside of
itself. (cold blooded)

Invertebrates
• Invertebrates are by far the most numerous
animals on Earth.
• Nearly 2 million species have been identified to
date. These 2 million species make up about 98
percent of all the animals identified in the entire
animal kingdom.
• The true number of invertebrate species may be as
high as 100 million and that the work of
identifying and classifying invertebrate life has
only just begun.
symmetry
• Most animals have symmetry. Let’s look at
the different type of symmetry.
• Asymmetry
• Radial
• Bilateral
•Bilateral- Two halves of
an organism’s body are
mirror images of each
other.
•Radial symmetry- in which
the parts of the body are
arranged in a circle around
a central point.
•Asymmetry-When you
cannot draw straight line
to divide its body into
two or more equal parts.
Its body is not organized
around the center.
Giant clam mollusk
• I am a Nautilus Mollusk. I
rest on the ocean floor in the
daytime.
I swim at night. I eat shrimp
and algae.
To breathe or not to breathe
Animals have different ways to breathe. We
will the two ways that animals breathe:
• Gills
• Lungs
Animals have different methods of
locomotion and respiration.
• Gills-breathing organ of
fish:the organ that fish and
some other water animals use to
breathe, consisting of a
membrane containing many
blood vessels through which
oxygen passes.
•Lung-respiratory
organ in vertebrates
that transfer oxygen into
the blood and remove
carbon dioxide from it.

Let’s move
Animal have different body parts that allows
them to move. Let’s learn about some of
those ways.
• Tube feet
• Tentacles
• Appendages
• Tube feet- radial canals
connected to dozens of tiny
suckers; used for feeding,
moving around, or
performing other functions
depending on the species.
• Starfish - ampullae
and tube feet
• Tentacles- a long flexible
organ around the mouth or on
the head of some animals,
especially invertebrates such as
squid, used in holding,
grasping, feeling, or moving
•Appendage- a body
part or organ that
projects from the main
part of the body, e.g. a
tail, wing, or fin.

• Some animals reproduce asexually, but
most reproduce sexually. We will learn the
different types of each.
• Budding
• Fragmentation
• Conjugation
• Internal fertilization
• External fertilization
Some animals reproduce asexually,
but most sexually.
• Budding-a form of asexual
reproduction in which an
outgrowth of the parent
pinches of and eventually
separates to form a new
individual.
• Great shot of asexual budding in a prepared
slide of Hydra.
•Fragmentation- parts
of organism break off
and then develop into
a new individual that
is identical to the
original one.
• Conjugation-the simplest
form of reproduction, in
which two single-celled
organisms such as bacteria or
protozoans link together,
exchange genetic information,
and then separate.
•Internal fertilizationWhen the eggs of a
female is fertilized
inside of the female.
•External fertilizationWhen the eggs of the
female is fertilized
outside of the female
body.
Animals may go through a variety of
developmental stages.
• Complete metamorphosis-a
change that involves the four
stages of egg, larva, pupa, and
adult in insects such as
butterflies, beetles, flies, and
bees
• Incomplete
metamorphosis- -a change
that involves the three
stages: egg, nymph and
adult.

ems/metamorphosis/
• Larvae-the wingless
immature worm-shaped
form of many insects that
develops into a pupa or
chrysalis before becoming
an adult insect
• Screwworm Fly
Larvae
• Embryo-animal in initial
developmental stage: the
developing young of an
animal from the earliest
stages after conception up
to birth or hatching.
• Human
mouse
• Nymph-the larva of some insects
such as mayflies, dragonflies,
and grasshoppers that resembles
the adult and develops into the
adult insect directly, without
passing through an intermediate
pupa stage.
• Pupa-developing insect inside
cocoon: an insect at the stage
between a larva and an adult in
complete metamorphosis, during
which the insect is in a cocoon
or case, stops feeding, and
undergoes internal changes.
Adult
• The stage after a series
of developmental
changes.
