Animals that have a backbone
9. What are invertebrates?
Animals that do not have a
backbone
10. How many phyla are
invertebrates?
8
How many are vertebrates?
1
11. What is the difference
between vertebrates and
invertebrates?
A vertebrate has a backbone,
the invertebrates do not have a
backbone.
12.What are sponges?
Simple animals with pores and
canals.
13. What do sponges look like?
Look like underwater plants of
various shape and color.
14. Draw two examples of
sponges:
1
2
15. Explain how the sponges
use a network of pores and
canals:
Water enters the sponge
through the pores, flows
through the canals into the
center of sponge then out the
top.
16. Where in the ocean do
sponges spend their entire
adult life?
Attached to something on the
bottom of the ocean.
17. Describe the function of
the three types of cells found in
sponges:
a)Cells to grab incoming
food
b)Cells to make sperm and
egg
c)Cells to make the
exoskeleton
18. Explain how the sponge
uses filtration:
Water, oxygen, food, and
sperm are filtered out of the
water as it moves down the
canals.
19. Describe the sexual and
asexual ways that sponges
reproduce:
Sexual
By fertilizing an egg with
sperm that it filtered out of
the water
Asexual
By budding! A new sponge
grows off of the side of the
adult, breaks off and becomes
a separate sponge.
20. List a practical way tht
we use sponges. What part of
the sponges are we actually
using:
We use the skeleton of the
sponge for cleaning.
21. Draw the following 5
examples of animals found in
the phylum coelenterata:
HYDRA
Sea Anemone
Brain coral
22. Why are coelenterates
called the stinging celled
animals?
They have special cells that
fires poison darts at their prey
when they are touched.
23.What are tentacles?
Arm like parts that surround
the mouth.
24. Where are the stinging
cells located on the
coelenterates?
ON THE TENTACLES!
25. What is the job of the
tentacle?
Presents the stinging cells for
use. Grabs food and puts it in
the mouth.
26. Explain how and why the
stinging cells are fired by the
coelenterate:
Automatically fires just as
soon as a prey touches a
tentacle.
27. Explain how the stinging
cells and the tentacles work
together to get food:
Stinging cells paralize prey,
tentacles put it in the mouth.
28. What is a colony
creature?
Groups of animals that
function as one animal.
29. Give two examples of
colony creatures;
CORAL REEF
PORTUGESE MAN OF
WAR
30. Why can you always see
the tentacles of some
coelenterates and you can’t
always see the tentacles of
others??
Different fishing styles!
Jellyfish, sea anemome dangle
their tentacles out all the time.
Coral only stick out their
tentacles at night.
31. Describe the cell layers of
the coelenterates:
Endoderm = inner layer
Jelly layer = middle layer
Ectoderm = outer layer
32. Explain how swimmers
can be injured by the stinging
cells of the coelenterates,
when it is impossible for the
human to be a food source.
The human accidentally
touched the tentacle and the
stinging cell fired
automatically.
33. How will a person be
affected by the sting of a
jellyfish?
Burns – hurts- pain- body part
paralized!
33. If a swimmer is stung by a
jellyfish, what should he or
she do?
HOBBLE out of the water
Get it off!
Put meat tenderizer on the
sting.
34. Complete the following
chart regarding parasitic
flatworms:
a
Tapeworm
Hanging in the small
intestine
b
Blood Fluke
In the blood stream
c
Liver Fluke
In the liver
35. How does the tapeworm
get its food?
It soaks up the food that has
been digested by its host.
36. What is the difference
between IMMATURE
PROGLOTTIDS, MATURE
PROGLOTTIDS, AND
GRAVID PROGLOTTIDS?
Immature proglottids are new
tapeworm segments.
Mature proglottids have
developed sex organs
Gravid proglottids are full of
eggs.
37. Sketch the tapeworm and
label the three types of
proglottids.
Scolex
Mature proglottids
Immature
proglottids
Gravid
proglottids
38. Describe the tapeworm
life cycle:
1.Eggs are swallowed
2.Eggs hatch in stomach
3.Worm swims to the small
intestine.
4.Bites into the wall of the small
intestine and waits for your
food.
39. Describe the two ways
that people can get
tapeworms into their body:
Method # 1:
Eat raw pork containing the
tapeworm.
Method # 2:
Swallow eggs off of our
hands that we picked up
throughout the day.
Which method do you think
happens most often?
We swallow eggs off of our
hands.
40.What is the Trichina?
Tapeworm that gets into pork.
41. Describe two ways that
tapeworm infection can be
controlled:
Cook pork well done
And
Wash your hands good after
using the bathroom.
42. Why is the planarian
considered a free living
organism?
It is a consumer, but it is not a
parasite.
43. What does the planarian
eat? Where is it found?
Eats = Night feeder. Eats dead
things in the water
Found = Ponds and streams all
over the world.
42. Draw and label a
planarian:
Eye
spots
chemoreceptors
mouth
What are:
Eye spots?
Photoreceptors
that allow the
worm to measure
light and dark.
No image!
Chemoreceptors
Organs used by
the worm to
follow the
chemical trail of
some dead
decaying thing.
Funky digestive system?
Incomplete digestive
system. Food and
body waste use the
same hole.
How can a planarian
eat objects bigger
than it is?
Planarian follows the chemical
trail until it finds the dead fish.
Pukes up its stomach, and lays it
on the fish. Eats, then pulls it in.
43. What is an incomplete
digestive system?
A system where there is only
one opening into it. Mouth
only,no anus.
44. Draw and explain how the
planarian can use
REGENERATION as a way to
reproduce and a way to heal
itself:
Pulls itself into,then grows back
missing parts. 1 becomes 2.
If a piece of the worm is eaten,
it can grow missing body parts.
45.What is a
HERMAPHRODITE?
A creature that contains male
and female sex organs.
Why is it useful? It can breed
with any other planarian that
it meets.

Just inside the RECTUM.
c) Why is the way they
reproduce so annoying to us?
The females crawl in and out of
the anus to lay her eggs. It
makes the anus ITCH.
D) Why do they reproduce this
way?
To get you to scratch and spread
her eggs.
52.Why do most restaurants
INSIST that all employees
wash their hands after they use

siphons?
To let water in and out of the
bivalve.
