Grade VI - Science Classification of animals

1. SIR MICHAEL ANGEL S. SAJOT

2. VERTEBRATES?
Vertebrates are animals with
backbone.

3. MAMMALS
Mammals are endotherms or warm-blooded creatures. They can
regulate they own heat to maintain temperature. The bodies of
mammals are covered with hair or fur. Since they produce their
body heat, they bodies are lined with sweat glands.
Sweat glands are glands that releases water to lower their body
temperature if it is too hot.
Sebaceous glands are glands that releases fat to prevent the loss
of too much body moisture and body heat.

4. MAMMALS
Monotremes
Marsupials
Placental Mammals

5. REPTILES
Reptiles are ectothermic or cold-blooded. They cannot regulate
their body temperature. Their skin is covered in hard dry scales
made of keratin. Keratin prevents water from the skin cells.
Reptiles are generally egg-laying animals.
Most of the reptiles have a three-chambered heart, which is very
distinct to reptiles, except alligators and crocodiles which possesses
four-chambered hearts.

6. REPTILES
Sphenodontia
Squamata
Crocodilia
Testudinata and
Chelonia

7. AMPHIBIANS
Similar with reptiles, they are cold-blooded animals. Amphibians
have moist skin. They lack hair, scales and feathers. Their skin can
be smooth like the frog skin or rough like the toad.
The female amphibians lay their eggs in water, after which the
male would release his sperm in water.

8. AMPHIBIANS
Anura
Apoda
Urodela
Trachystoma

9. BIRDS
Birds are generally warm-blooded animals. Their skin is covered
with feathers. Similar to some reptiles they have four-chambered
heart. They are lightweight and have hollow bones to aid them in
flight.

10. BIRDS
Philippine Eagle
Maya or Sparrow
Dove

11. FISH
Fish are mostly vertebrates. They are also cold-blooded animals.
Their skin is covered with scales. The limbs of the fish are modified
into fins for swimming. They also have gills for breathing under
water. They lay their eggs outside their bodies.
Their body is divided into three parts: head, trunk and tail.

12. FISH
Jawless Fish
Cartilaginous Fish
Bony Fish
