Step 1: Understand the Definitions

- Vertebrates: Animals that have a backbone (spinal column). Examples include fish, birds, mammals, reptiles, and amphibians.
- Invertebrates: Animals that do not have a backbone. Examples include insects, spiders, jellyfish, worms, and mollusks.

Step 2: Analyze the Provided List of Animals

The worksheet provides a list of animals to classify:
1. Jellyfish
2. Spider
3. Fish
4. Bird
5. Dog
6. Lizard
7. Frog
8. Clam
9. Sea Urchin
10. Sea Sponge
11. Earthworm
12. Chimp
13. Cow
14. Elephant
15. Whale
16. Lion
17. Ostrich
18. Kangaroo
19. Shrimp
20. Snake
21. Toad
22. Centipede
23. Flatworm
24. Leeches
25. Lobster
26. Starfish
27. Shark
28. Snail
29. Crocodile
30. Crawfish

Step 3: Classify Each Animal

We will classify each animal based on whether it has a backbone (vertebrate) or does not have a backbone (invertebrate).

#### Vertebrates
- Animals with a backbone:
1. Fish
2. Bird
3. Dog
4. Lizard
5. Frog
6. Chimp
7. Cow
8. Elephant
9. Whale
10. Lion
11. Ostrich
12. Kangaroo
13. Snake
14. Toad
15. Shark
16. Crocodile

#### Invertebrates
- Animals without a backbone:
1. Jellyfish
2. Spider
3. Clam
4. Sea Urchin
5. Sea Sponge
6. Earthworm
7. Centipede
8. Flatworm
9. Leeches
10. Lobster
11. Starfish
12. Snail
13. Crawfish

Step 4: Write the Answers in the Worksheet

The worksheet has two columns labeled "Vertebrates" and "Invertebrates." You should write the names of the animals in the appropriate column based on your classification.

#### Vertebrates Column
- Fish
- Bird
- Dog
- Lizard
- Frog
- Chimp
- Cow
- Elephant
- Whale
- Lion
- Ostrich
- Kangaroo
- Snake
- Toad
- Shark
- Crocodile

#### Invertebrates Column
- Jellyfish
- Spider
- Clam
- Sea Urchin
- Sea Sponge
- Earthworm
- Centipede
- Flatworm
- Leeches
- Lobster
- Starfish
- Snail
- Crawfish

Final Answer

Here is the final classification:

#### Vertebrates
- Fish
- Bird
- Dog
- Lizard
- Frog
- Chimp
- Cow
- Elephant
- Whale
- Lion
- Ostrich
- Kangaroo
- Snake
- Toad
- Shark
- Crocodile

#### Invertebrates
- Jellyfish
- Spider
- Clam
- Sea Urchin
- Sea Sponge
- Earthworm
- Centipede
- Flatworm
- Leeches
- Lobster
- Starfish
- Snail
- Crawfish

Explanation

This classification is based on the presence or absence of a backbone, which is a key characteristic used to differentiate vertebrates from invertebrates. Vertebrates are more complex animals with internal skeletons, while invertebrates have simpler body structures without backbones.

Final Answer:
\boxed{
\text{Vertebrates: Fish, Bird, Dog, Lizard, Frog, Chimp, Cow, Elephant, Whale, Lion, Ostrich, Kangaroo, Snake, Toad, Shark, Crocodile} \\
\text{Invertebrates: Jellyfish, Spider, Clam, Sea Urchin, Sea Sponge, Earthworm, Centipede, Flatworm, Leeches, Lobster, Starfish, Snail, Crawfish}
}
