How Do We Classify Animals?
By
Sonya Cameron
Things to look at
• Some animals are vertebrates: have
backbone.
• Some are invertebrates : do not have a
backbone.
• Are they warm blooded: the temperature
of their blood does not change with
environment.
• Are they cold blooded: The temperature of
their blood changes.
•Do they breath through lungs or
gills?
•Where do they live?
•Do they have hair?
•What do they look like?
•What type of symmetry do they have?
(Symmetry is matching pattern of body
shape).
•How do they get their energy (what do
they eat)?
Look at All the Different Animals
How Can We Group Them?
Invertebrates
Most animals are invertebrates: They have no
back bone.
Types of invertebrates:
Cnidarians (jelly fish and coral) Cnidarians have
a simple digestive system with a mouth. They
also have radial symmetry (their parts repeat
around a center).
Echinoderms (star fish and sea cucumber) They
have spiky skin and usually have suckers.
Sponges (ocean animals with no tissues, organs,
or body symmetry).
Arthropods: (Lobsters, crabs, and insects) They have
a hard covering called an exoskeleton and bilateral
symmetry (left side looks like right).
Mollusks: (clams and oysters, squid, snail, and
octopuses). They have soft bodies but some have
shells.
Worms
Vertebrates: Have backbones and include
dogs, cats, humans, birds, alligators, and
more.
Carnivore: Eats meat only
Herbivore: Eats plants only
Omnivore: Eats plants and meat
Scavengers: Eat the remains of
recently dead organisms
Predators and Prey
Predators hunt other animals for food.
Animals of Prey are animals that are hunted
for food.
Can you name some animals that are
predators?
Can you name some animals that are prey?
Scientists classify animals into
six groups
• Mammals
• Reptiles
• Amphibians
• Birds
• Insects
• Fish
Mammals
• Have fur or hair
• Breathe with lungs
• Female mammals make milk for their
babies
Examples of Mammals
What others can you name?
Reptiles
• Have scaly skin
• Most reptiles lay eggs
• Live in dry or wet habitats
Examples of Reptiles
Amphibians
• Begin their lives in water
• Have smooth, moist skin
• Live in both water and land
Examples of Amphibians
Birds
• Only animals with feathers
• Have two wings and two legs
• Young hatches from eggs
Examples of Birds
Insects
• Have three body parts and six legs
• Have hard body coverings
• Young hatch from eggs
Examples of Insects
Fish
• Live in water
• Breathe with gills
• Have fins to move through water
