4.6

The Animal Kingdom

Welcome to Biology!

• This week, we will discuss the last animal groups of 4.6: the vertebrates
• First, I will ask some questions about the last lesson
• And then we will get started with new animals!

Name the two different types of Myriapods we have. Can you give one difference between them?

What was special about Crustacean legs?

How many body parts do Arachnids have?

1. 1
2. 2
3. 3
4. 4

Can you give one reason why we need insects?

Now onto the new groups!

• The new groups all belong to the vertebrates. Look up in your notes what vertebrates were again.
• Take out your notebook and a pen, because you'll need to take notes again!

Today, we will discuss:

Fish

Reptiles

Amphibians

Mammals

Birds

Fish

• Aquatic
• Most lay soft eggs, fertilized externally
• Some are livebearing
• Cold-blooded
• Scales
• Gills

Amphibians

• Water & land
• Most lay soft eggs, fertilized externally
• Cold-blooded
  
• Skin is moist and wet
• Undergo metamorphosis

Remember metamorphosis? If you don't, check your notes on the insects we discussed last lesson

Reptiles

• Live only on land
• Eggs fertilized internally + have hard, leathery shells
• Cold-blooded
• Lungs
• Dinosaurs were also reptiles

Birds

• Live on land + in the air
• Eggs fertilized internally + have hard, chalky shells
• Warm-blooded
• Wings & feathers
• Beaks look different based on what they eat

Mammals

• Live on land
• Eggs fertilized internally
• Monotremes, marsupials or placentals
  
• Have milk for their young
• Warm-blooded
• Hair or fur

Mammals

• Monotremes: lay eggs (platypus)
• Marsupials: give birth, but let them develop in pouches (kangaroo)
• Placentals: babies develop fully in placenta

That was it!

That was a lot of information, but now it's time for a little fun. Try to find examples of all these animals outside, and take a picture of them. You can upload the pictures on Itslearning again!

Good luck!
