Teacher Page

• The learner will be able to classify living
  things into groups based on structure.
• The learner will be able to understand that
  organisms are classified according to their
  structural similarities which mirror their
  evolutionary relationships.
• The teacher can use this production to show
  similarities and differences in vertebrates.
• The students should use science journals to write
  in answers as the teacher proceeds through the
  program.
• The teacher should use this as an introduction to
  vertebrates and seize the opportunities to have
  class participation by leading a guided
  discussion.

VERTEBRATE CLASSIFICATIONWrite these questions
and try to answer them to the best of your
ability in your science journal!

• 1. What is the kingdom in which all
  vertebrates are classified?
• 2. What is the phylum in which all vertebrates
  are classified?
• 3. What is the subphylum in which all
  vertebrates are classified?

Why am I a vertebrate, and how am I like fish,
amphibians, birds, and mammals?

ALL VERTEBRATES BELONG TO THESE CATEGORIES

• KINGDOM ANIMALIA
• PHYLUM CHORDATA
• SUBPHYLUM VERTEBRATA

TALKING IGUANA

As a green iguana, let me tell you all
the characteristics that Vertebrates share.
They are

• backbone
• bilateral symmetry
• coelomate animals that have endoskeleton
• closed circulatory system
• efficient respiratory system
• complex brain and nervous system

5 Major Groups

FIVE MAJOR GROUPS OF VERTEBRATAES Create a chart
with Fish, Amphibians, Birds, Reptiles, and
Mammals at the top in your science journal.
Under each heading write their characteristics!Cli
ck on each underlined group to learn more! Fish
Amphibians Birds

Mammals

Fish

• 3 Types 1.Jawless (ex.-Lamprey, hagfish)
• 2.Cartlaginous Fishes(ex.-shark)
• 3.Bony Fishes(ex.-tuna, jack)
• Ectotherms- body temperature is dependent on the
  surroundings.
• 2 chambered heart
• Have gills

9
AmphibiansDOUBLE-LIFE

• Examples- Frogs, Toads, Salamanders.
• As adults, they live on land, but rely on water
  for breeding and egg development.
• All go through metamorphosis, in which the young
  gradually lose their tails and gills and develop
  legs, lungs, and other adult structures.
• Ectotherms- body temperature is dependent on the
  surroundings.
• 3 chambered heart

10
Reptiles

• Examples-snakes, lizards, turtles, crocodiles,
  and alligators.
• Ectotherms- body temperature is dependent on the
  surroundings.
• Most have 3 chambered heart, but crocodiles have
  a 4 chambered heart.
• Have lungs
• scaly skin reduces loss of body moisture on land.
• Have amniotic egg- embryo in amniotic fluid.

11
Birds

• Have feathers.
• Forelimbs modified into wings.
• Have amniotic egg- embryo in amniotic fluid.
• Incubate eggs in nests.
• Endotherms-animals that maintain a constant body
  temperature.
• Have thin hollow bones enabling flight.
• Have lungs.

12
Mammals

• Examples- Humans, Dogs, Cats, Kangaroo ect.
• Endotherms-animals that maintain a constant body
  temperature.
• 4 chambered heart
• Have mammary glands
• Have lungs
• Have hair for insulation
• 
  3 Types of
  Mammals

3 Types of Mammals

3 Types of Mammals

• Monotremes- lay eggs (example-platypus)
• Marsupials- young develop in pouch of
  mother.(example-kangaroo, koala)
• Placental-carry young inside the uterus until
  development is nearly complete.
• (example-humans, dogs, cats)
