1. LIVING THINGS CLASSIFICATION
THE FIVE KINGDOMS

2. ANIMAL KINGDOM CLASSIFICATION

3. ANIMAL KINGDOM CLASSIFICATION
INVERTEBRATES: animals without a backbone
•Sponges
•Cnidarians.
•Molluscs.
•Annelids.
•Arthropods.
•Echinoderms.

4. ANIMAL KINGDOM CLASSIFICATION
VERTEBRATES: animals with a backbone
•They belong to phylum chordata
ASCIDIAS: Chordates but not vertebrates

5. ANIMAL KINGDOM CLASSIFICATION
Vertebrates characteristics:
•Skeleton with spinal column.
•Digestive system.
•Excretory system.
•Sexual reproduction.
•Nervous system with brain and spinal chord.

6. SPONGES
SPONGES characteristics:
•They live attached to an underwater
surface
•Their body is covered with pores.
•They feed filtering water. Water goes
out through the osculum.

7. CNIDARIANS
Gastrovascular cavity
Mouth-anus
Characteristics:
•Digestive cavity with a single
opening (mouth-anus).
•Tentacles to catch preys.
Tentacles

8. ANNELIDS
Characteristics
•Bodies are long and cylindrical.
•Bodies divided in segments (metameres).
•They breathe through the skin. (cutaneous
respiration).
•Some of them have distinct sexes but other
are hermaphrodites (sexual reproduction)
Earthworms
Leeches

9. ANNELIDS

10. MOLLUSCS
Characteristics
•External layer called mantle. Inside they have the visceral mass with organs.
•Internal or external shell.
•Muscular foot.
•Radula: a tonge with teeth for biting and chewing.

11. MOLLUSCS
Types
•Gastropods:
•Spiral shell or no shell (slugs).
•Head with four tentacles.
•Mainly herbivores.
•Cephalopods:
•Head with eyes and mouth.
•Tentacles to catch prey.
•Carnivores.
•Bivalves:
•No head.
•Two shells.
•Filter feeders.

12. Arthropods
Characteristics
•Body divided into segments.
•Jointed limbs (articulated limbs).
•Exoeskeleton with muscles for movement.
•Breathe through trachea or gills.

13. Arthropods
Characteristics
•Metamorphosis (in some cases).
•Moult to grow.

14. Arthropods
Types:
•Myriapods: Separated head and body
(trunk) formed by many metameres with
legs.
•Arachnids: Body divided in two
parts, cephalotothorax (4 pair of legs)and
abdomen.
•Crustaceans: head and cephalothorax
(usually 5 pairs of legs).
•Insects: Head, thorax (3 pairs of legs) and
abdomen.

15. FISH
Characteristics:
• Adapted to live in water because:
•They breathe trough gills.
•They have fins to move.
•Their shape is fusiform.
• Their swim bladder fills up with air
allowing them to float.
• They are poikilotherms: don´t control their
body temperature.
•They are mainly oviparous.

16. FISH
Types:
Cartilaginous: skeleton made of cartilage.
Bony: Bony skeleton.

17. Amphibians
Characteristics:
• They undergo metamorphosis:
•Larvae breathe through gills and
use a tail as a caudal fin to swim.
•Adults develop limbs, and breathe
through lungs and the skin (cutaneus
respiration).
•Poikilotherms.
•They are oviparous and lay eggs in water.

18. Amphibians
Types:
Anurans: lose the tail when adults. Four
limbs of different sizes.
Uroldels: don´t lose the tail when adults.
Four limbs of the same size.

19. Reptiles
Characteristics:
Adapted to live on land:
•Breathe through lungs.
•Body covered with scales that
prevent from dehydration.
•Lay eggs covered with a thick
layer that allow them to survive on
land.
Poikilotherms.

20. Birds
Characteristics:
Adapted to fly:
•Wings and feathers.
•Hollowed bones.
•Sternum highly developed.
•Air sacs.
Homeotherms.

21. Mammals
Characteristics:
Females with mammary glands.
Body covered with fur.
Homeotherms.
Most of them viviparous.

22. Mammals
Types:
Monotrems: oviparous, but with
mammary glands and fur.
Marsupials: viviparous. Babies are
born underdeveloped. Feed on
mammary glands that females have in
a pouch.
Placentals: vivipaous, babies are born
completely developed
