Mammals Fish Birds Reptiles Amphibians
MammalsMammals
Characteristics: Have teeth Have hair Are warm blooded Have a single jaw bone Have inner ear bones Produce milk for their young
MammalsMammals
Mammals have larger brains and seem to be the most capable learners.
All mammalian mothers nourish their babies with milk.
FishFishCharacteristics: Are cold-blooded vertebrate
(backbone) Live in water Usually have paired fins, gills, and
scales
FishFishMost fish lay large numbers of
eggs, but some have live birth.
Most fish breathe by drawing water over four or five pairs of gills.
AmphibiansAmphibiansCharacteristics: Are cold-blooded vertebrate
(backbone) Lay their eggs in water Lack any skin coverings such as
fur, scales or feathers
AmphibiansAmphibians Young amphibians tend to resemble sm
all fish. Amphibian means "two lives," a referenc
e 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.
BirdsBirds
Characteristics: Have feathers Lay eggs Have bodies specially adapted for
flight Have a beak rather than teeth
BirdsBirdsTheir nearly hollow bones
provide lightweight strength. Birds now live almost
everywhere on Earth.
Characteristics: Have scales Lay leathery eggs on land Are often called cold-blooded
because they can't regulate their own body temperature
ReptilesReptiles
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.
