  Vertebrate Animal Kingdom

Classifying Vertebrates

• Objectives
• Understand the classification and identification
  of the animal kingdom
• Become confident with the organization of fish
  in the animal kingdom

3
Organization of Vertebrates

• The vertebrates of the animal kingdom are
  divided into five main groups. Choose one of the
  groups to learn more about them.
• 1. Fish
• 2. Amphibians
• 3. Reptiles
• 4. Birds
• 5. Mammals

FishThe Water Dwellers

• Most fish are cold blooded vertebrates that live
  in water. Scientists believe that fish were the
  only vertebrates on Earth for about 150 million
  years.
• Scientists classify fish living today into three
  classes.

5
Classes of Fish

• Jawless
• Cartilage
• Bony

6
Jawless Fish

• Jawless fish have a round mouth, tube like body,
  single fins, no scales, and a skeleton made of
  cartilage.

Incorrect

• The shark is a cartilage fish. Unlike the
  jawless fish, the cartilage fish have movable
  jaws, scales, paired fins, and skeletons made of
  cartilage.

• The Tuna is a bony fish. Bony fish have scales,
  well-developed sense organs, fins, and skeletons
  made of bone.

AmphibiansLiving in Water and on Land

• Amphibians spend part of their lives in water and
  part on land. They have moist, smooth skin that
  allows for the exchange of oxygen and carbon
  dioxide. They are cold-blooded. The three types
  of amphibians that exist today are frogs and
  toads, salamanders, and caecilians.

22
ReptilesThe Move to Land

• Reptiles are cold blooded and have thick, dry,
  waterproof skin covered with scales. As a
  reptile grows, its skin is shed by molting.
• The four orders of reptiles living today are
  turtles, alligators and crocodiles, lizards and
  snakes, and tuataras.

23
BirdsTaking to the Air

• Birds are vertebrates that have wings, a beak,
  two legs, and a body covering of feathers. Birds
  were the first warm-blooded vertebrates to have
  insulated body coverings made of feather,
  adaptations for flight, hollow bones, and eggs
  with hard shells that allow for incubation.
  Most, but not all, birds fly.

24
MammalsThe Fur Bearers

• A mammal is a warm-blooded vertebrate that has
  hair, feeds milk to its young using mammary
  glands, has oil glands to lubricate skin and
  hair, and has sweat glands to regulate body
  temperature.
