ANIMAL DIVERSITY
Systematics
• study of biological diversity and its origins
Its arms
TAXONOMY focus on properly describing, identifying, classifying, and naming of organisms.
CLASSIFICATION
focus on placing organisms within groups that show their relationships to other organisms.

Didinium sp. ►body is barrel-shaped with cilia restricted to 2 girdles ► the anterior has a proboscis elevation at the tip is an expansible cytostome ►macronucleus is Cshape ► carnivorous
Paramecium sp.
• Body is slipper‐shape with a blunt anterior and pointed posterior region • Body is covered by a firm pellicle and a cilia used for locomotion, protection and sweeping of food materials • Food materials comes in thru the oral groove leading to the cytopharynx • Fecal materials are expelled thru a cytoproct found posteriorly
Vorticella sp.
• Bell‐shaped • 2 rows of cilia are confined to the oral region • Macronucleus is worm‐like while micronucleus is dot‐ like • Attached to the body is a long stalk with contractile fibers or myonemes
Stentor sp.
• Trumpet‐shape ciliate • Macronucleus is monoliform or bead like • May either be attached to substrate or free‐ swimming
Phylum Dinozoa
• Dinoflagellates: single‐celled organisms • Occur as motile cells with 2 flagella • Possess equatorial and posterior longitudinal flagellum located in grooves • Body is either naked or covered by cellulosic plates or valves or by cellulose membrane
Ceratium sp.
• Lives in freshwater and marine habitats • Girdle divides it into anterior epicone and posterior hypocone • Contains a centrally located
