Kingdom Animalia
~ Characteristics ~
Multi-cellular
•Eukaryotic with no cell walls
• Heterotrophs (consumers)
•motile
•
Characteristics Cont.
Animal Movement
• Motile, mobile
–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.
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 to
organisms weighing many tons
a mesozoan
blue whale
Animal Habitats
• Most animals inhabit the seas,
with fewer in fresh water and
even fewer on land.
Animal Cell Diagram
Animal Bodies
• The bodies of most animals 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, free-floating, or
weakly swimming.
Radial
Symmetry
Bilateral Symmetry
• Animals with bilateral
symmetry are most wellsuited for directional
movement.
Bilateral Symmetry
~Invertebrates~
• No backbones
• 95% of all animals are in
this group
~ Protection
and
Support ~
–exoskeleton – a hard, waxy
coating on the outside of the
body
– endoskeleton – support
framework within the body
~Invertebrate
Phylum Porifera~
• Sponges
• simplest form of animal life
• live in water
• Do not move around
• no symmetry
• 5000 species
~Invertebrate
Phylum Porifera~
• Examples:
Tube Sponge,
Glass Sponge,
Sea Sponge
~Invertebrate
Phylum Cnidaria~
• Live in water
• Most have tentacles
• catch food with stinging
cells
• gut for digesting
~Invertebrate
Phylum Cnidaria~
 2 different
shapes
 Medusa - like a
jellyfish
 Polyp - like a
hydra
~Invertebrate
Phylum Cnidaria~
• Examples Jellyfish, Hydra,
sea anemones, and
corals
• Soft bodies
~Invertebrate
Phylum Mollusca ~
• Hard Shells
• Live on land or in water
• have a circulatory system and a
complex nervous system.
• Important food source for humans
~Invertebrate
Phylum Mollusca ~
Class
Gastropoda
–snails and slugs
–may have 1 shell
–stomach-footed move on stomach
~Invertebrate
Phylum Mollusca ~
Class Bivalves
–2 shells hinged
together
–clams, oysters,
scallops and mussels
~Invertebrate
Phylum Mollusca ~
Class Cephalopods
–squids and octopuses
–internal mantel
~Invertebrate
Phylum Platyhelminthes:
worms ~
 Flatworms
Example: Planaria, tape worms
Flat, ribbon-like body
 Live in water or are parasites
 lives in intestines of host absorbing
food
bilateral symmetry
Regeneration- regrow body parts
~Invertebrate
: Flat WORMS Cont.~
 eyespots detect light
 scavengers & predators
 lives in intestines of host
absorbing food
 food and waste
go in and out the same opening
Examples
of flat worms
~Invertebrate
Phylum Annelida ~
Are Segmented worms
Have Body divided into
segments (sections)
–Live in water or
underground
–have a nervous and circulatory
system
~Invertebrate
Annelida Cont~
• Earthworms
• eat soil and
breakdown
organic matter,
wastes provide
nutrients to soil
More annelids:
segmented worms
• leeches
• parasites that feed on blood of other
animals
~Invertebrate
Phylum Arthropod ~
• Body divided into sections/segments
• Exoskeleton – outer
– Molt – shed exoskeletons as they grow
• Jointed appendages (legs)
• well developed nervous system
• largest group of organisms on earth
~Invertebrate
Phylum Arthropod ~
• Include the classes:
–Crustaceans, arachnids,
centipedes, millipedes, and
***Class insecta
• Classified into classes according
to the number of legs, eyes and
antennae they have.
~Invertebrate Phylum
Arthropods~
• Insects- 3 body sections
1. Head – antenna
2. Thorax – midsection (wings and legs)
3. Abdomen – (internal organs/structures)
– grasshoppers, ants, butterflies,
bees
~ Phylum
