PHYLA
GENERAL CHARACTERISTICS
 Most complex of all kingdoms
 Multicellular (made of many cells)
 They obtain food from OUTSIDE SOURCES
 They move from place to place to get food (at
least at one point in their lives)
 Heterotrophs/consumers who eat other things
for energy
 Cell membrane- no cell wall
HOW ANIMALS ARE CLASSIFIED:
1- BODY
STRUCTURE
2- DNA
C- HOW IT DEVELOPS
WHAT COMMON CHARACTERISTICS
DO ALL THESE CREATURES SHARE
SINCE THEY ARE ALL ANIMALS?!
1234-
The angler fish
The Aye-Aye is a nocturnal
animal that lives in Madagascar.
The Kiwi bird, although only
the size of a chicken lays an
egg that weighs about 1
pound!.
All animals, no matter their size, appearance or
habitat they live in carry out the SAME functions.

Get food and oxygen

Keep internal
conditions stable

Move

Reproduce
Animals Move?!
How about an oyster?
 Coral?
 Barnacle?
 Glass Lizard?

How do things move?
Animals Reproduce!

Sexual reproduction:
the fertilization of
an egg by sperm
◦ (2 sex cells join)

Asexual
reproduction: a new
organism reproduces
another organism
similar to itself
◦ (one parent)
Classification of Animals
The animal kingdom is
divided in to phyla.
 All vertebrates are
divided into one
phylum (CHORDATA),
while all the other
invertebrates make
up the remaining
animal phyla.

BASIC BODY CHARACTERISTICS OF
ANIMALS
Body symmetry - the way body parts are
arranged around a point or central axis.
Directions on the body - used to describe
areas on the body of an animal.
Pattern of body development - a sequence
of developmental steps.
BODY SYMMETRY
BILATERAL THE BODY CAN BE
DIVIDED INTO TWO
IDENTICAL HALVES BY
ONLY ONE SPECIFIC
PLANE THROUGH THE
LONGITUDINAL AXIS.
BODY SYMMETRY
RADIAL THE BODY CAN BE
DIVIDED INTO TWO
IDENTICAL HALVES
BY ANY PLANE THAT
PASSES THROUGH
THE LONGITUDINAL
AXIS.
BODY SYMMETRY
ASYMMETRICAL THE BODY HAS NO
DEFINITE SHAPE
AND CANNOT BE
DIVIDED INTO
TWO IDENTICAL
HALVES.
Sea sponge is
asymmetrical

Developmental Stages
1.ZYGOTE-THE FERTILIZED EGG.
2. EMBRYO-THE DEVELOPING FERTILIZED
EGG.
3. FETUS-THE EMBRYO HAS DEVELOPED
TO THE POINT THAT IT BEGINS TO
RESEMBLE THE MATURE ORGANISM.
9 Phyla of the Animal kingdom
1)Porifera
6) Mollusca
2)Coelenterata
7) Echinoderm
3)Flatworms
8) Arthropoda
4)Roundworms
9) Chordata
5)Segmented worms
Porifera
Means “having pores”
asymmetrical
Ex: sponges
Coelenterata
Sac-like body
Have tentacles
Ex: hydras, jelly fish, coral,
 sea anemones
Radial symmetry
3 Phyla of Worms:
Flatworms
Roundworms
Segmented worms
Molluska:
Hard shell surrounding soft body parts
Live in water & damp places
Examples:
Snail, & Sea Scallop
Only a few do not have shells:
 Octopus & Sea slug
Echinoderms:
Means “spiny-skin”
Star shaped
Radial symmetry
Spiny
Ex:
Starfish & Sea Urchin
Arthropoda:
Makes up 75% of the animal kingdom
Basic Characteristics:
hard external skeleton
segmented body
jointed legs
Ex: beetle, milli & centipede, spider, crab
Chordata:
Vertebrates
Have internal skeleton
Vertebral column
Limbs
CLASSES: fish, amphibians, reptiles, birds,
mammals
