28
True or false: All animals are vertebrates.
False. The majority are invertebrates whereas vertebrates make up a small percentage.
29
What is the difference between being poisonous and venomous?
Being poisonous means it hurts you if you eat it. Being venomous means it hurts if it bites you.
30
What are the nine phyla?
Porifera, Cnidaria, Echinodermata, Mollusca, Platyhelminthes, Nematoda, Annelida, Arthropoda, and Chordata.
31
What are the three qualifiers for being an animal?

36
33
What is the name for animals whose gut development starts with the mouth?
Protostomes
34
What is the name for animals whose mouths develop second?
Dueterostomes
35
Defining characteristics of Phylum Porifera:
Lack of specialized tissues, pump water through pores to eat, and are sessile as adults.
36
Defining characteristics of Phylum Cnidaria:
Radial symmetry, carnivorous, stinging cells, and polyp or medusa forms.
37
Main animal of Phylum Porifera:
Sponges
38
Animals in Phylum Cnidaria:
Jellyfish, coral, and sea anemones.
39
What happens to coral if the water is too warm?
It starts to "spit out" the algae that it lives with symbiotically, which leads to bleaching and death.
40
Key features of Phylum Platyhelminthes:
Growth by adding to body mass and not molting, well-defined head and tail, and a gut with one opening.
41
Key animals of Phylum Platyhelminthes:
Flatworms and flukes.
42
What is Schistosomiasis
A parasitic disease second to malaria; Is contracted by coming into contact with contaminated water.
43
Key features of Phylum Nematoda:
Growth by molting, mostly parasitic, and unsegmented bodies.
44
Key animals of Phylum Nematoda:
Roundworms
45

Body segmentation
47
Most notable animals from Phylum Annelida:
Earthworms and marine worms.
48
Key features of Phylum Mollusca:
Defined tissues, have bilateral symmetry, don't molt, are protostomes, and have a shell (aka a mantle, but there are exceptions).
49
Key creatures from Phylum Mollusca:
