• annelids
• arthropods
• nematodes
• flatworms
• chordates
• molluscs
• echinoderms

I-Book page 12

Vertebrates / invertebrates:

Ask yourself one question?

"Does it have a backbone?"

I-Book pages 7-9

Chordates:

• Fish
• Amphibians
• Reptiles
• Birds
• Mammals

Mammals:

• They live on land and in water. Some can even fly.
• They breathe through lungs.
• They have hair or fur.
• They are warmblooded.
• Female mammals have babies drink milk from mammary glands (suckle).
• Most give birth to live young. 

Birds:

• They live on land and water. Many can fly.
• They breathe through lungs.
• They have feathers and wings.
• They are warmblooded.
• They reproduce with hard shells. 

Reptiles:

• They live on land on in water.
• They breathe through lungs.
• They have dry scales.
• They are coldblooded.
• They lay eggs with leathery shells. 

Amphibians:

• They live on land on in water. 
• As an adult they breathe through lungs and in the water they breathe through their skin. The young animals breathe through gills.
• They have smooth, moist skin.
• They are coldblooded.
• They reproduce with soft eggs in water. 

Fish:

• These animals all live in water.
• They breathe through gills.
• Their bodies are covered in slimy scales.
• They are coldblooded.
• They reproduce with soft eggs in water. 

Which chordate phylum lays eggs with a hard shell?

1. birds
2. reptiles
3. amphibians
4. fish

Which chordate phylum breaths with gills when they are young and with lungs as an adult?

1. birds
2. reptiles
3. amphibians
4. mammals

Which chordate phylum has feathers?

1. birds
2. reptiles
3. amphibians
4. mammals

Which chordate phylum has fur?

1. birds
2. reptiles
3. amphibians
4. mammals

Which chordate phylum is the only phylum in which all animals give birth to living young?

1. birds
2. reptiles
3. amphibians
4. mammals

Read this page in your I-Book. make sure you click all the question marks.

Cnidarians:

• Invertebrate animals that have a liquid skeleton.
• They have hollow bodies shaped like bags
• They have stingy tentacles.
• Examples: jellyfish and anemones

Annelids:

• Invertebrate animals with a liquid skeleton.
• They have long thin bodies divided into rings (segments).
• Examples: garden worms & leeches

Arthropods:

• Invertebrate animal with an exoskeleton.
• Arthropod means jointed leg, all these animals have jointed legs.
• They all have bodies that are divided into segments.
• Because they have an exoskeleton they grow by molting.
• They all have some kind of feelers or antennae.

Nematodes:

• Invertebrate animals with a liquid skeleton.
• They are also known as round worms.
• They have long, thread-like bodies.
• Some live in soil, but many are parasites that live in plants and animals.

Flatworms:

• Invertebrate animals with a liquid skeleton.
• They have a flattened body with a mouth at one end. 
• Some live in fresh water, but most are parasites of animals, such as a human tapeworm. 

Chordates:

• Vertebrate animals are animal with a backbone.
• They have an endoskeleton made of either bone or cartilage.

Molluscs:

• Invertebrate animals with a liquid skeleton.
• Their bodies are soft but not segmented. 
• Many of them have one or two shells to protect them.
• They have a muscular ‘foot’ to burrow or around with.

Echinoderms:

• Invertebrate animals with a liquid skeleton.
• These animals all live in the sea.
• They have tough, spiny skins.
• They body has a pattern of five parts.
• They move around on tube feet.

Arthropods:

There are 4 classes in this phylum:

• insects
• arachnids
• crustaceans
• myriapods

Arachnids:

• This is the spider group.
• They have bodies divided into two parts.
• They have four pairs of legs and no wings.
• They have no antennae and paralyze their prey with poison.

Insects:

• Their skin (cuticle) is waterproof and can stop them from losing much water.
  
• They have a body in three parts: the head, the thorax and the abdomen.
• The thorax has 3 pairs of legs and usually two pairs of wings. 
• They have one pair of antennae and compound eyes.
• They breathe through holes on the side of their body called spiracles.
• They do metamorphosis.

Crustaceans:

• Nearly all of these animals live in water (woodlice are an exception).
• They breathe oxygen using their gills.
• They have more than 4 pairs of legs and less than 20 pairs of legs. 
• Many have a chalky exoskeleton. This protects them like a suit of armor. 
• Crustaceans always have two pairs of antennae.

Myriapods:

• These animals have long- thin segmented bodies.
• The centipedes and the millipedes belong to this group of animals.

Which arthropod class has got 2 pairs of antennae?

1. insects
2. arachnids
3. crustaceans
4. myriapods

To which arthropod class do scorpions belong?

1. insects
2. arachnids
3. crustaceans
4. myriapods

Which arthropod class has 3 pairs of legs?

Name an example of a crustacean?
