Transcript of Animal Classification
similarities and differences
Why are there so many different organisms on earth?
Why do some of these different organisms have similar characteristics?
We can organize all LIFE by their
Organization of Life
Group organisms together based on anatomical similarities
Scientists group all living things into the following six kingdoms
The systematic grouping of organisms into categories on the basis of evolutionary relationships or physical appearance.
The questions have to have
We can organize these six kingdoms even further!
How Do We Classify Exactly?
Allows us to keep track of the
3 to 10 million different living things
1a. Does eat Meat.........go to 2
1b. Does not eat meat
2a. Is larger size........go to 3
2b. Is smaller size
3a. Is a carnivore
3b. Is an omnivore
Identify the Animal
Does it have a longer neck?
Does it have a shorter neck?
Does it not have stripes?
Does it have stripes?
Is the body covered in stripes?
Is the bosy not covered in stripes?
Archaebacteria are found in extreme environments:
- boiling water
- thermal vents
- highly acidic environments
Complex and single celled.
There are many kinds and they are found everywhere - most are beneficial.
Slime molds and algae are protists.
Sometimes they are called the
odds and ends
kingdom because its members
are so different from one another.
Protists include all microscopic organisms that are not bacteria, not animals, not plants and not fungi.
Examples of fungi:
Most fungi are multicellular and consists of many complex cells.
Plants are multi-cellular organisms that produce their own food.
Examples of plants:
- flowering plants
With over 250,000 species, the plant kingdom is the second largest kingdom.
The animal kingdom is the largest kingdom with over 1 million known species
Squid, Octopus, Snail, Clam
Insects, Crabs, etc
- Jellyfish and Coral
Animals can mate if they
are the same species!
We name animals using
- “Binomial” =
- “Nomenclature” =
*Genus is always capitalized
Species is always lower-case
* Both are always italicized
There are 7 levels of classification that describe a species
Genus and species are the most specific levels of organization
How Do We Name Organisms We Classify?
Can be classified together because they all produce milk (mammal)
Can be classified together because they all have same characteristics.
(claws, fur, strong upper limbs)
More About The Kingdoms...
Does it has symmetry? YES.........
Is it a circle?........YES...
It's a Sea Urchin!
Organize questions onto a chart called a
Questions must have a
"yes" or "no"
The more levels of organization that two organisms share, the more closely related the two organisms are!
...go to pink
....go to blue
- have DNA
- can grow and develop
- respond to stimuli
- keep homeostasis (a balance)
- obtain and use energy
