Vertebrates
 Vertebrates are animals with backbones.
 These can be made into smaller groups.
 These are Mammals, Reptiles, Amphibians,
Birds and Fish

Mammals
 Humans are mammals. The word mammal
comes from the Latin mamma, meaning
breast, because female mammals produce
milk to nurse their babies. Nearly all
mammals give birth to live young, and all are

body temperature regardless of
VerteBrates environmental conditions. They are
vertebrates and use lungs to breathe air and
are the only animals that grow hair. Mammals
probably appeared on Earth some 200 million
years ago.

Reptiles
 Reptiles have been around for 300 million
years, and during the age of the dinosaurs,
they ruled the Earth. Those days are long
gone, and those giants have vanished, but
some 6,500 species of reptiles still thrive
today. Crocodiles, snakes, lizards, and turtles
are all reptiles. Most reptiles live on land, and
most lay eggs. They are vertebrates, and,
unlike any other animals, are covered in
scales. They are cold-blooded, and regulate
their body temperature by seeking or avoiding
the sun's heat.
Amphibians
 Amphibians lead double livesﾑone in water
and one on land. Many begin life with gills,
then develop lungs as they age. They are
vertebrate animals that include frogs, toads,
salamanders, and newts as well as odd,
wormlike caecilians (seh-SILL-yuns). They
are cold-blooded, using the environment to
regulate their body temperature. Early
amphibians were the first animals to leave the
sea and venture onto land, forming a crucial
link from fish to terrestrial reptiles.
