26-1 Introduction to the
Animal Kingdom
List the characteristics that
define Kingdom Animalia.
What percentage of animals
are invertebrates?
Can you identify the animals
in the photo to the right?
Animal Origin
Label the following groups
and events on the time line
above:
Earth Forms
Prokaryotes
Eukaryotes (Protists)
Animals
Cambrian Explosion
Single cell
Stalk

In the space below, describe what you think the figure above
represents. Hint: This is NOT the same individual organism
over time. Each arrow represents an evolutionary event.

In the space below, describe what you think the figure above
represents. Hint: This IS the same individual organism over
time. How does this figure and the one on the previous slide
compare? Label the phyla to the right.

Body Plan: Coelom & Germ Layer “Fates”
Label the diagrams including which is an acoelomate, pseudocoelomate, and
eucoelomate. Identify and list the germ layers, including what each gives rise to.
Body Plan: Symmetry & Position
Planes of

Plane of
symmetry
Label the three types of symmetry shown, including which phyla exhibit each. Also
label the following: Oral, Aboral, Anterior, Posterior, Dorsal, Ventral, Cephalized.
Body Plan: Comparison
Evolutionary Trends
Compare and contrast the body plans of these phyla, including Phylum Chordata.
Evolutionary Trends: Digestive Systems
Identify which of these phyla have a “2-way” digestive system, and which have a
“1-way” alimentary canal (AKA digestive tract).
Evolutionary Trends: Respiratory Systems
Compare and contrast the gas exchange systems in these phyla. (To which phylum
do insects belong?) How do the phyla not shown exchange gases?
Evolutionary Trends: Circulatory System
Compare and contrast the circulatory systems in these phyla. How do the phyla not
shown perform whole-body transport (open vs. closed vs. no system)?
Evolutionary Trends: Excretory Systems
Compare and contrast how these
phyla rid of metabolic (nitrogenous)
waste. How do the phyla not shown
perform this function?
Evolutionary Trends: Nervous Systems
Describe the nervous systems of these phyla. Which
are cephalized and have a central nervous system?
What of the phyla not shown?
Evolutionary Trends: Movement & Support
Describe, compare and contrast the musculoskeletal
systems of these phyla. What type of skeletal
system do the muscles contract against?
