• Classification of animals.
• Vertebrates and invertebrates.
• Classification of the invertebrates.
• Zoo Assignments

I-Book pages 10-13

Classification of animals:

- no cell wall

- no chloroplasts

- nucleus

I-Book pages 7-9

Vertebrates / invertebrates:

Ask yourself one question?

"Does it have a backbone?"

I-Book pages 7-9

Classification groups:

today we are going to discuss the phyla of the animal kingdom

I-Book pages 10-13

8 Phyla: 

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

I-Book page 12

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.
