Species is unique
Thus, Categories within Kingdoms

How to remember?

Or how about this one . . . . . .
King Phillip Calls Opal For Great Soup.
Easier for your brain to remember one sentence that 8 individual words

•We only know a fraction of all the organisms that exist or have existed on Earth.
•Taxonomists give a unique scientific name to each species they know about whether it’s alive today or extinct.
Scientific Names
![Page 6: Basic Classification - Zoology. Classification of Organisms Kingdom Phylum Class Order Family Genus Species.](https://reader033.fdocuments.us/reader033/viewer/2022061509/56649e675503460f94b6341b/html5/thumbnails/6.jpg)
Scientific Names
The scientific name comes from one of two “dead” languages
– Latin or ancient Greek.
Why use a dead language?
They are static – don’t change
![Page 7: Basic Classification - Zoology. Classification of Organisms Kingdom Phylum Class Order Family Genus Species.](https://reader033.fdocuments.us/reader033/viewer/2022061509/56649e675503460f94b6341b/html5/thumbnails/7.jpg)
So Why Use a Scientific Name?
Maybe if we use an example using an animal you know.

•There are at least 50 common names for the animal shown on the previous 7 slides.
•Common names vary according to region.
•Soooo……why use a scientific name?
It is unique for that organism!
![Page 16: Basic Classification - Zoology. Classification of Organisms Kingdom Phylum Class Order Family Genus Species.](https://reader033.fdocuments.us/reader033/viewer/2022061509/56649e675503460f94b6341b/html5/thumbnails/16.jpg)
Scientific Names Helps eliminate confusion as to
which organism you are dealing with.
Thus the Mountain Lion is known as . . .
Felis concolor

Many (maybe even most) classification systems use . . . 2 main domains
– Archaebacteria– Everything else
– Along with 5 kingdoms

10. Ephemeroptera - mayflies
Insects in the order Ephemeroptera usually live in water as a nymph or larvae for a year or more and then emerge as an adult and live for a matter of hours or days
Notice the three tails on adult and nymph.
Mayflies have three and stoneflies have two.
![Page 53: Basic Classification - Zoology. Classification of Organisms Kingdom Phylum Class Order Family Genus Species.](https://reader033.fdocuments.us/reader033/viewer/2022061509/56649e675503460f94b6341b/html5/thumbnails/53.jpg)
Plecoptera – (stoneflies)
All species of Plecoptera are intolerant of water pollution and their presence in a stream or still water is usually an indicator of good or excellent water quality.
Note the two “tails” – stoneflies have two “tails” while mayflies have three
![Page 54: Basic Classification - Zoology. Classification of Organisms Kingdom Phylum Class Order Family Genus Species.](https://reader033.fdocuments.us/reader033/viewer/2022061509/56649e675503460f94b6341b/html5/thumbnails/54.jpg)
Mecoptera – (scorpionflies)
“scorpionflies” and “hanging flies”
Mecopterans are overwhelmingly predators or consumers of dead organisms
![Page 55: Basic Classification - Zoology. Classification of Organisms Kingdom Phylum Class Order Family Genus Species.](https://reader033.fdocuments.us/reader033/viewer/2022061509/56649e675503460f94b6341b/html5/thumbnails/55.jpg)
Trichoptera – (caddisflies)
The larvae of many species make protective cases of silk decorated with gravel, sand, twigs or other debris. The name "Trichoptera" comes from Greek: θρίξ (thrix, "hair") + πτερόν (pteron, "wing").
