How are Organisms Classified?•Classification: the grouping of anything according to its
similar characteristics.•The science of classifying organisms is known as
taxonomy.

How are Organisms Classified?•There are eight classification
groups of living things:•Domain•Kingdom•Phylum•Class•Order•Family•Genus•Species

What is an Animal?
•We will be focusing specifically on the Kingdom Animalia and its 9 phyla. •Vertebrates: animals with
backbones• Invertebrates: animals without a
backbone•97% of all animal species are
invertebrates!

What is Symmetry?
•To classify animals, scientists also look at symmetry, or how the body parts are arranged.•Radial symmetry: body parts are arranged in a
circle around a center point.•Bilateral symmetry: body can be divided into two
mirror image halves.•Asymmetry: no pattern of symmetry

What are the Characteristics of ALL Animals?•Characteristic 1: Animals cannot make their own food (consumers).•Characteristic 2: Animals digest their food.•Characteristic 3: Many animals move from place
to place.•Characteristic 4: Animals have many cells.•Characteristic 5: Animal cells have nuclei and
organelles (eukaryotic cells).

What are the 9 Different Phyla in Kingdom Animalia?•Phylum Porifera•Phylum Cnidaria•Phylum Platyhelminthes•Phylum Nematoda•Phylum Mollusca•Phylum Annelida•Phylum Arthropoda•Phylum Echinodermata•Phylum Chordata

Phylum Porifora •Aquatic organisms•Lack tissues and organs•Asymmetrical, mostly sessile (do not move)•Example: sponges
![Page 12: Classification & The Animal Kingdom](https://reader035.vdocuments.us/reader035/viewer/2022081415/568164db550346895dd72d51/html5/thumbnails/12.jpg)
Is this a “real” sponge?
•Sponges are: •Aquatic organisms•Lack tissues and
organs•Asymmetrical, mostly
sessile (do not move)

Phylum Cnidaria•Aquatic organisms•Radial symmetry•Digestive cavity with one opening•Tentacles with stinging cells•Examples: jellyfish, corals, hydra, sea anemones
![Page 14: Classification & The Animal Kingdom](https://reader035.vdocuments.us/reader035/viewer/2022081415/568164db550346895dd72d51/html5/thumbnails/14.jpg)
Phylum Platyhelminthes•Bilaterally symmetrical worms•FLAT bodies•Digestive system with one opening•Examples: parasitic and free-living species•Examples: Flat worms
![Page 15: Classification & The Animal Kingdom](https://reader035.vdocuments.us/reader035/viewer/2022081415/568164db550346895dd72d51/html5/thumbnails/15.jpg)
Phylum Nematoda•Round, smooth worms •Bilateral symmetry•Digestive system with 2 openings• Free living and parasitic forms•Examples: roundworms
![Page 16: Classification & The Animal Kingdom](https://reader035.vdocuments.us/reader035/viewer/2022081415/568164db550346895dd72d51/html5/thumbnails/16.jpg)
Phylum Mollusca•Soft-bodies, many with a hard shell or foot-like
appendage.•Aquatic or terrestrial•Examples: clams, snails, squid, octopuses
![Page 17: Classification & The Animal Kingdom](https://reader035.vdocuments.us/reader035/viewer/2022081415/568164db550346895dd72d51/html5/thumbnails/17.jpg)
Phylum Annelida•Round worms with segmented bodies•Bilateral symmetry•Terrestrial and aquatic•Examples: earthworms, leeches, and marine
polychaetes

Phylum Arthropoda•Largest animal group, bilateral symmetry •Have an exoskeleton, segmented bodies, and pairs
of jointed appendages•Land and aquatic•Examples: insects, crustaceans, and spiders

Phylum Echinodermata•Marine organisms•Radial symmetry•Spiny/leathery skin•Water-vascular system with tube feet•Examples: sea stars, sand dollars, sea urchins

Phylum Chordata•Organisms with internal skeletons and specialized
body systems•At some point all have a backbone (or notochord),
gill slits, and a tail•Examples: fish, amphibians, reptiles, birds, and
mammals
