Kingdom Animalia
~ Characteristics ~
Multi-cellular
Eukaryotic with no cell walls
 Heterotrophs (consumers)
motile

Characteristics Cont.
Animal Movement
 Most
animals are capable of
complex and relatively rapid
movement compared to
plants and other organisms.
Animal Reproduction
 Most
animals reproduce
sexually, by differentiated
haploid cells (eggs & sperm).
 Most
animals are diploid,
meaning that the cells of
adults contain two copies of
the genetic material.
In addition to
Characteristics of Life
1. Living things are organized.
2. Living things are made up of cells.
3. Living things metabolize.
4. Living things maintain an internal
environment.
5. Living things grow.
6. Living things respond.
7. Living things reproduce.
8. Living things evolve.
Animal Sizes
 Animals
range in size from no
more than a few cells (like the
mesozoans) to organisms
weighing many tons (like the
blue whale).
a mesozoan
blue whale
Animal Habitats
 Most
animals inhabit the seas,
with fewer in fresh water and
even fewer on land.
Animal Cells
 Animal
 Animal
cells, are eukaryotic
cells lack the rigid cell
walls that characterize plant
cells.

Animal Bodies


The bodies of most animals (all except
sponges) are made up of cells organized
into tissues.
Each tissue is specialized to perform specific
functions.
Cells->tissues->organs->organ sys >organism
Animal Symmetry




Describes how animal body
structures are arranged
Allows animals to move in different
ways
Cnidarians and echinoderms are
radially symmetrical.
Most animals are bilaterally
symmetrical.
Symmetry:
 The
most primitive
animals are
asymmetrical:
No symmetry
Radial Symmetry
 forms
that can be divided into
similar halves by more than
two planes passing through it.
 Animals
with radial symmetry
are usually sessile, freefloating, or weakly swimming.
Radial
Symmetry
Bilateral Symmetry
Animals
with bilateral
symmetry are most
well-suited for
directional
movement.
Bilateral Symmetry
~ Protection
and Support ~
 not
all animals have a
skeleton, divided into 2
groups:
 exoskeleton – a hard, waxy
coating on the outside of
the body

endoskeleton – support
framework within the body
~Invertebrates~
No
backbones
95%
of all animals are
in this group
~Invertebrate
Phylum Porifera~

Sponges

Do not move around
