Classification?
 Animals
are separated into
groups or categories so that
they are more easily studied
and discussed by scientists
and others.
 Mammals
 Fish
 Birds
 Reptiles
 Amphibians
Mammals
Characteristics:
 Have
teeth
 Have hair
 Are warm blooded
 Have a single jaw bone
 Have inner ear bones
 Produce milk for their young
Mammals
 Mammals
have larger brains and
seem to be the most capable learners.
 All mammalian mothers nourish
their babies with milk.
Fish
Characteristics:
 Are
cold-blooded vertebrates
(backbone)
 Live in water
 Usually have paired fins, gills, and
scales
Fish
 Most
fish lay large numbers of
eggs, but some have live birth.
 Most
fish breathe by drawing
water over four or five pairs of
gills.
Amphibians
Characteristics:
 Are
cold-blooded vertebrates
(backbone)
 Lay their eggs in water
 Lack any skin coverings such as
fur, scales or feathers
Amphibians
Young amphibians tend to resemble
small fish.
 Amphibian means "two lives," a
reference to the change that frogs go
through as they move from egg to
tadpole to frog.
 Even as adults, most frogs and other

amphibians must stay close to water.
Birds
Characteristics:
 Have
feathers
 Lay eggs
 Have bodies specially adapted for
flight
 Have a beak rather than teeth
Birds
 Their
nearly hollow bones
provide lightweight strength.
 Birds now live almost
everywhere on Earth.
Reptiles
Characteristics:
 Have scales
 Lay leathery eggs on land
 Are often called cold-blooded
because they can't regulate their
own body temperature
Reptiles
 Reptiles
do not use energy to fuel
internal "furnaces"
 Although reptiles breathe through
lungs, some reptiles can also
absorb oxygen in water through
their mouth.
