• 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 CLASSIFICATION
Write these questions and try to answer them
to the best of your ability in your lab
notebook!
• 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?

As a green iguana, let me
tell you all the
characteristics
that Vertebrates share.
backbone They are:
bilateral symmetry
coelomate animals that have
endoskeleton
closed circulatory system
5 Major
efficient respiratory system
Groups
complex brain and nervous system
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!Click on each
underlined group to learn more!
Fish
Amphibians
Birds
Reptiles
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
Amphibians
“DOUBLE-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
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.
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.
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.
REVIEW
