Reflection
• Prompt: Write 3 questions that you have
about Jelly Fish and Coral Reef.
What are the six kingdoms of
living things?
4 Characteristics of animals
1. Many celled organisms
2. Obtain their food by eating other
organisms
3. Reproduce sexually
4. Move from place to place
An animal that does not have a
backbone is called an
nvertebrate
i__________.
• Most animal
species (95%) are
invertebrates
• Can you name
some
invertebrates?
• Jellyfishes, worms,
snails, crabs,
spiders & insects
An animal that has a backbone is
ertebrate
called a V__________.
• Can you name
some vertebrates?
• Fishes,
amphibians,
reptiles, birds and
mammals
Classification of Animals
• Vertebrates
• Invertebrates
• 35 Major Groups
called a Phylum
Are Sharks vertebrates?
• Yes
• Although they
have cartilages
instead of
bones, they
have a skeleton
and a backbone
Sea anemone and many circular
adial
animals exhibit R______
ymmetry
S_______
• What are some
characteristics of Radial
Symmetry Animals?
• Do not have distinct
front or back ends
• Lives in the ocean
• Senses their
environment in all
directions
The balanced arrangement of a
butterfly’s body is called
ymmetry
ilateral
B_______
S________
• What are some
characteristics of
Bilateral Symmetry
Animals?
• Larger & More complex
than radial symmetry
animals
• Moves more quickly
• Sense organ in the front
Is a Sponge an animal or a
plant?
• Sponge is an animal
• Although it cannot
move around from
place to place sponge
take food into their
bodies
What do sponges eat?
• Tiny
organisms
such as
bacteria and
protists
• Sponge gets
its oxygen
from water
• Network of
spikes support
the sponge
Sponge Larva
• Sponge reproduce
asexually and sexually
• Sponges do not have
separate sexes
• At any one time of the
year, some sponges are
producing eggs and
others are producing
sperms
What are Cnidarians?
More on Cnidarians
• Unlike sponges, cnidarians have
specialized tissues
• Muscle like tissues for swimming
• Anemones stretch out
How does cnidarians obtain and
digest food?
• Cnidarians captures
its prey by using its
stinging cells to inject
venom
• Then the cnidarian’s
tentacles pull the prey
animal to its mouth
• From there the food
passes into a body
cavity where it is
digested.
Jellyfish Facts
•
•
•
•
They are not used to make Jelly
98% Water
No Heart or Blood
Most don’t have a brain (except
Box Jellyfish)
• Most only detect light. Some have
24 eyes (Box Jellyfish)
• When stung, Vinegar (not urine) is
the best treatment
• Irukandji Jellyfish (size of fingernail)
can kill you with a single sting.
How are coral reefs made?
• Built by cnidarians
1. Free swimming coral
larva attaches to a solid
surface ( broken shell,
sunken ship)
2. The coral polyp
produces a hard, stony
skeleton around its soft
polyp body
3. Over thousands of
years, as live corals add
their skeletons, the reef
grows
Reflection
• Prompt: Write 5 facts that you learned in
the video.
