This document discusses the classification of animals according to their structure, diet, and reproduction method. It classifies animals as either vertebrates or invertebrates based on whether they have a backbone. Vertebrates are then broken down into mammals, birds, fish, reptiles, amphibians, while invertebrates lack a backbone. Each group's defining characteristics are described such as body covering, breathing organ, and whether they are oviparous (born from eggs) or viviparous (born alive from the mother). Examples are provided to demonstrate how specific animals like crocodiles, butterflies, pigs, and penguins can be classified.

1. ANIMAL
CLASSIFICATION

2. CLASSIFICATION OF ANIMALS
… ACCORDING TO THEIR STRUCTURE (BODY):
• VERTEBRATE: They’ve got a backbone.
• INVERTEBRATE: They haven´t got a backbone.

3. CLASSIFICATION OF ANIMALS
… ACCORDING TO THE FOOD THEY EAT:
• CARNIVOROUS:
• HERBIVOROUS:
• OMNIVOROUS:
They eat animals.
They eat plants and fruits and
animals.
They eat plants and fruits.

4. CLASSIFICATION OF ANIMALS
… ACCORDING TO THE WAY THEY ARE BORN:
• VIVIPAROUS:
• OVIPAROUS:
They are born from mum´s stomach.
They are born from eggs.

10. AMPHIBIANS CHARACTERISTICS
• They are vertebrates.
• They are oviparous.
• They have got moist skin.
• They breathe with their
gills (tadpoles) or lungs
(adults).

11. INVERTEBRATES CHARACTERISTICS
• They are invertebrates.
• They are oviparous.
• They have got differents
body covering: no
protection, shell or
exoskeleton.
• They breathe with their
trachea.
• They are cold-blooded.
