3. Invertebrates are
animals without a
backbone, they are
pluricelulars and
eukaryotes. Are ovipars.
There are such groups:
Gastropods
Bivalves
Cephalopods
Insects
Arachnids
Crustaceans
Miriapods

4. Gasteropods
The gasteropods have
five important parts:
The mouth
The stomach
The shell
The anus and
the heart.

5. Bivalves
The parts of the bivalves are
very similar than the parts of
the gasteropods:
The mouth
The foot
The shell
The mantle
And the siphons (exhalant-
inhalant)

6. CEPHALOPODS
The cephalopods are animals
very weird.
He have tentacles, and, there are
many in each tentacle suckers.
In this family are: octopus, sepia
and squid. But are other animals
of this family they have
characteristics very similars.

7. INSECTS
e insects are commons
cause they are all
e world except the poles.
e a lots of tipes of insects in
e Earth, and there
rloximalety
0.000 known species of insects.
Abdomen
Head
Thorax
Eyes
Antennae

8. ARACHNIDS
of the arachnids are very few of species:
pions.

9. CRUSTACEANS
Crustaceans are
canival, eat their
own species.
All crustaceans live
in the sea and the
rivers.
He have a thin shell
and freacualy a big
Tweezers.
Antennae
Tweezers
Abdomen
Cephalothorax

10. MIRIAPODS
The miriapods tend to
have many legs and are
very weird. In this family
of invertebrates are the:
Millipedes
Scalopendra
And centipede
Tend to have a
exoskeleton.

11. The life of the invertebrates
Gasteropods: Are herbivorous, do not usually live in extreme climates.
Bivalves: Usually live in beaches and the sea, and have a shell, some
are carnivores and other herbivorous.
Cephalopods: They live in the sea, are carnivores and in cases of
emergency can remove ink to confuse the predator.
Insects: Are very casuals in the world. Are carnivores and other are
herbivorous and canivals. They have an exoskeleton.
Arachnids: Have eight legs and live in all the world.
Crustaceans: Live in the sea or the rivers. Have an exoskeleton.
Miriapods: Usually are biger than other invertebrates. Are carnivores.

12. THE RELATIONSHIP OF THE
INVERTEBRATES WITH THE
HUMANS:
There are many
species of
invertebrates in the
world and this makes
them quite typical
animals in our lives
In Asia some
invertebrates are
typical food.

13. BIBLIOGRAPHI
