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?
BEARDED DRAGON
ALL VERTEBRATES BELONG TO THESE CATEGORIES:
• KINGDOM ANIMALIA
• PHYLUM CHORDATA
• SUBPHYLUM VERTEBRATA
TALKING IGUANA
• backbone• bilateral symmetry• coelomate animals that have endoskeleton• closed circulatory system• efficient respiratory system• complex brain and nervous system
As a green iguana, let me tell you all thecharacteristics that Vertebrates share. They are:
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!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.
• 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
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) REVIEW
As an amphibian, an
Argentine Horned Frog,
let’s review the
characteristics of
vertebrates!
