This presentation was made for my 3rd grade homeschool son. It is divided into invertebrates and vertebrates. It discusses basic characteristics, life cycle, and types of animals.
7. INVERTEBRATES: SPONGES
Characteristics
•Sponges take in water from
pores and release it at the top
•The water holds the sponge
up
•They feed and "breathe" by
filtering the water that flows
through them
•Phylum Porifera
Sponges
10. INVERTEBRATES: SPONGES
Special Adaptation
•When they find that the water circulating through them
has more silt and large particles that could block their
canal system, they automatically close their pores and
protect themselves!
Sponges
22. Characteristics
•Radial symmetry, central
mouth
•No central nervous
system
•No circulatory system,
heart or blood
•Some have tentacles with
stinging cells
•Can reproduce sexually or
asexually (not all species
can do both though)
Cnidarians
INVERTEBRATES: CNIDARIANS
24. Types of Cnidarians
a)All forms of Jellyfish
b)Anemones: Are not mobile

INVERTEBRATES: CNIDARIANS
25. *Special note: Comb jellies are a side step away
from jellyfish. They are in the phylum
Ctenophora. They look similar, but are different
in some important ways.
- Comb jellies use cilia flapping on their sides to
move. They do not contract a bell like jellyfish.
- Comb jellies use cells called colloblasts to
capture their prey. These cells stick to the prey,
not harpoon them.
- They have two (2) holes. While true jellies have
a sealed bell with only one opening, comb jellies
have a small opening at the top of their body and
one at the bottom so that water can flow through
them.
- They often have plates for protection on the
outside of their bodies.

26. Types of Cnidarians
c)Corals: create hard calcium carbonate
skeletons. They are not mobile.

28. Mollusks
•Internal or external shell
•Largest marine phylum
•Numerous molluscs also live
in freshwater and terrestrial
habitats
•Three universal features are
a mantle, a radula (teeth),
and a nervous system.
INVERTEBRATES: MOLLUSKS
•Most shells are made of
calcium carbonate
•Circulatory systems
•In reproduction, molluscs
may change gender
37. Bivalves
Characteristics
•Mollusk with two hinged
parts that are
symmetrical
•ctenida (specialized
gills)
•Tiny eyes, mantle, no
head
•Filter feeders
INVERTEBRATES: BIVALVES
43. Characteristics
•Mollusk with one shell
(univalved)
•Bilateral symmetrical
•ctenida (specialized
gills)
•Tiny eyes, mantle, no
head
•Can have up to six
kidneys
•Sexes are separate
•Feed by scraping algea
INVERTEBRATES: MONOPLACOPHORA
Monoplacophora
48. Characteristics
•Mollusk with dorsal shell
which composed of eight
separate plates
•Bilateral symmetrical
•Most of the body is a
snail-like foot
•Have gills
•3 chambered heart
•Feed by scraping algea
INVERTEBRATES: POLYPLACOPHORA
Polyplacophora
53. Characteristics
•Mollusk
•Tentacles on head
•Eye spots on
tentacles
•Mucous skin
•Shell can be external
or internal made of
calcium carbonate
•Muscular foot
INVERTEBRATES: GASTROPODS
Gastropods
59. Characteristics
•Flat, soft, and paper
thin
•Many are parasitic
•Others are free living
•Bilateral symmetry
•Brain: small clusters of
nerves
•Get most of their
oxygen through diffusion
Flatworms
INVERTEBRATES: FLATWORMS
65. Characteristics
•Nematodes are small
and smooth
•Have a complete
digestive system
•Bilateral symmetry
•Parasitic
•Have muscles that
move down the length of
that entire round body
INVERTEBRATES: ROUND WORMS
Round Worms
75. Arthropods
•75% of all animals
•Exoskeleton made of chitin
•Molt to grow new
exoskeleton
•Jointed appendages (legs)
INVERTEBRATES: ARTHROPODS
•Advanced sense organs
•Open circulatory systems
•Metamorphasis
-Complete
-Gradual
78. Characteristics
•Chitinous exoskeleton
• 3-part body (head,
thorax and abdomen)
• 6 jointed legs,
compound eyes and one
pair of antennae
•Only invertebrate to fly
•Most diverse groups of
animals on the planet
•Represent more than
half of all known living
organisms
Insects
INVERTEBRATES: INSECTS
84. `
Characteristics
•Have biramous (two-
parted) limbs
•Bilateral symmetry
•5 pairs of legs
•Nauplius (form of larvae)
•Most are free-living
aquatic animals
•Some are terrestrial,
parasitic, and sessile
•Fished and farmed for
human consumption
INVERTEBRATES: CRUSTACEANS
Crustaceans
91. Characteristics
•8 jointed legs
•Exoskeleton
•Bilateral symmetry
•Two further pairs of
appendages that have
become adapted for

to 30cm in size

environment because
they don't have a waxy
cover like insects
