2. INVERTEBRATES jeopardy
 Animals that don’t have a backbone are called
invertebrates
 They are very diverse and they are 90% of all
animal species
 Some of them, such as jellyfish and worms have no
protection for their soft bodies.
 Others, such as snails and claims, have a soft body
inside a hard shell

3. Think of some animals that live in water, soil or air
that don’t have a backbone
WATER SOIL AIR

5. Nematodes
Plathelminths
Annelids

6. Poriferans
 No mouth, stomach or
other organs.
 Most live in oceans.
 Cannot move
 They filter the water to eat
(up to 1 ton to get 30g)
 They can grow back any
broken part.
Sponges feeding

7. CNIDARIANS: INVERTEBRATES WITH
STINGING CELLS
 They have tentacles
 They have a mouth
 On the ocean floor:
POLYPS: anemones and
corals
 Move: JELLYFISH

Anemone eat fish

8. WORMS
 They can grow back parts if they
lose parts
 Some worms can grow up up to 30
meters long (tenia)
 Plathelminths: flatworms and
tapeworm(tenia, parasite),
 Nematodes: stomach parasites,
intestinal worm, anisakis (fish) y
triquina (pig). No segments,
cilinders, pointed end.
 Annelids: cilinders, segmented.
More complex. Earth worm, leech
(sanguijuela).
Plathelmint:
Annelids: earthworm
Nematode:
intestine worm

9. TAPEWORMS

10. MOLLUSKS
 They live on land, salty and fresh
water
 Two main parts: mantle and foot.
 Some of them can make shells
from the mantle.
 Bivalves: Two valves and a foot
to dig and hide inside the sand or
to move
 Gastropods: they use the foot to
move. They have tentacles and
they have a special tongue:
radula.
 Cephalopods: No external shell*.
Foot is divided in tentacles to
move with propulsion.
squid
snail
octopus
clam
Mussel

11. EQUINODERMS: INVERTEBRATES WITH
ENDOESQUELETON MADE OF CALCIUM
PLATES
 Radial simetry, at least 5 sections
 They have special feet to move
 They can regenerate parts of their
bodies.
 They use tubes to feed. .
Sea stars
Sea Urchin
Sea cucumber
Regeneration

12. ARTHROPODS:ANIMALES CON PATAS ARTICULADAS.
4 GROUPS
Arthropods
Insects Arachnids Crustaceans Miriapods

13. ARTHROPODS
 Exoesqueleton made of chitin: resistant but not
flexible(they molt to renew it when they grow.
 Divided in head, torax and abdomen.
 They have articulated appendage (legs, wings or
antennae)

14. INSECTS
 The biggest arthropods group
 3 pairs of legs. 6 LEGS
 3 sections (head, thorax,
abdomen)
 Some groups with compound
eyes
 Adapted appendages in the
mouth
 Indirect growth: from larvae to
the adult (sometimes pupa
stage)
fly
beetle
grasshopper
butterfly

15. ARACHNIDS
 4 pairs of legs
 Most of them live on
earth
 Cephalothoreax and
abdomen.
 Chelicerae with
poison.
spider
DUST
MITES:
ÁCAROS
tick:garrapata
SCORPION

16. CRUSTACEANS
 They have 5 pairs of legs.
 Some of them have two
legs modified in claws
 On the ocean floor
 Microscopic ones:
zooplancton
 cephalothorax and
abdomen
crab
shrimp
lobsterzooplancton

17. MIRIAPODS: MILIPEDES AND
CENTIPEDES.
 Many segments
 Live under the rocks
 In fact they don’t have
neither 100 nor 1000 feet.
 They protect themselves
by rolling into a ball
(milipedes)
 Milipedes: 4 legs in each
segment
 Centipedes: 2 legs in
each segment
milipedes
Centipedes
(escalopendra)
