Vertebrates &
Invertebrates
Presented by Mr. Fisher
The Animal Kingdom
Multi-cellular (has many cells)
Cannot make their own food, they are
heterotrophs (must get energy by eating
plants and other animals
Are either vertebrates or invertebrates
– Vertebrates fish, amphibians, reptiles, birds
or mammals
– Invertebrates sponges, segmented worms,
echinoderms, mollusks, and arthropods
Vertebrates
ANIMALS WITH A BACKBONE!
Shared characteristics of vertebrates:
– Backbone
– Protective skin covering
– Inside skeleton
– Muscles
– Blood that circulates through blood vessels
– Lungs or gills for breathing
Vertebrates are divided into 5
groups:
–Fish
–Amphibians
–Reptiles
–Mammals
–Birds
Vertebrate- Fish
Have backbones
Cold-blooded
(ectothermic)
Obtain oxygen in
water through gills
Most lay eggs
Have scales
Have fins
Live in water
Vertebrate- Amphibians
Have backbones
Cold-blooded (ectothermic)
Can breathe in water with
gills early in life and breathe
on land with lungs as adults
Lay jelly-like eggs
Major groups are frogs,
toads, and salamanders
Vertebrate- Reptiles
Have backbones
Cold-blooded (ectothermic)
Breathe with lungs
Most lay eggs
In some reptiles the eggs hatch inside the
mother
Have scales or plates
Vertebrates- Mammals
Have backbones
Warm-blooded (endothermic)
Breathe with lungs
Have babies that are born alive
Have fur or hair
Produce milk to feed their young
Vertebrates- Birds
Have backbones
Are warm-blooded (endothermic)
Breathe with lungs
Lay eggs
Have feathers
Have a beak
Two wings
Two feet
InvertebratesANIMALS WITHOUT A BACKBONE!
90% of ALL animals are invertebrates
Largest group of invertebrates are the
arthropods
Invertebrates- Sponges
Very simple animals
Have many pores (holes) through which water
flows
Water moves into a ventral cavity and out
through a hole in the top
Sponges obtain their food and eliminate wastes
through this passage of water
Live in fresh or salt water
Invertebrates- Segmented Worms
Have long tube-like bodies
that are divided into
segments
Simplest organisms with a
true nervous system
Have a long digestive tube
that runs down the length
of the worm’s body
Examples: earthworms
and leeches
Invertebrates- Echinoderms
Similar parts
(arms) that
extend from the
middle body
outwards
They have tube
feet and spines
Examples:
starfish, brittle
stars, sea
cucumbers, or
sea urchins
Invertebrates- Arthropods
Have jointed legs
Live on land and in water
Have hard outer
coverings called exoskeletons
Have segmented bodies
and some have wings
Examples: insects,
spiders, and crustaceans
Invertebrates- Mollusks
Have soft bodies
Most have a thick muscular
foot for movement or to open
and close their shells
Live in salt or fresh water
or on land
Some have shells
Examples: snails, clams
and octopi
