1) What is it? Write a check mark (√) in the right box:

We need to classify each animal into one of the following categories:
- Fish
- Mammals
- Reptiles
- Amphibian
- Birds
- Vertebrates (animals with a backbone)
- Invertebrates (animals without a backbone)

> Note: All fish, mammals, reptiles, amphibians, and birds are vertebrates.
> Invertebrates include animals like insects, worms, snails, etc., which do not have a backbone.

Now let’s go through each animal:

| Animal | Fish | Mammals | Reptiles | Amphibian | Birds | Vertebrates | Invertebrates |
|------------|------|---------|----------|-----------|-------|-------------|---------------|
| 1) Monkey | | ✓ | | | | ✓ | |
| 2) Whale | | ✓ | | | | ✓ | |
| 3) Butterfly | | | | | | | ✓ |

✔ Explanation for Each:

1. Monkey – Mammal (has fur, gives birth to live young, feeds milk), so Mammals, Vertebrates
2. Whale – Mammal (lives in water but breathes air, has hair, feeds milk), so Mammals, Vertebrates
3. Butterfly – Insect, no backbone → Invertebrates
4. Worm – No backbone → Invertebrates
5. Cow – Mammal → Mammals, Vertebrates
6. Shark – Fish (lives in water, has gills, scales), so Fish, Vertebrates
7. Lizard – Reptile (dry skin, scales, cold-blooded), so Reptiles, Vertebrates
8. Crab – Crustacean, no backbone → Invertebrates
9. Lion – Mammal → Mammals, Vertebrates
10. Ladybug – Insect → Invertebrates
11. Toad – Amphibian (lives in water and land, moist skin, lays eggs in water), so Amphibian, Vertebrates
12. Snail – Mollusk, no backbone → Invertebrates
