🔹 Part 1: Circle the words that describe amphibians

We are given a grid of 9 phrases. We need to identify which ones correctly describe amphibians.

Here are the phrases:

| vertebrates | cold-blooded | produce milk for babies |
|-------------|--------------|-------------------------|
| usually has webbed feet | mostly lays eggs | breathes through their skin |
| their skin is smooth and slimy | warm-blooded | has feathers and wings |

Now, let’s go through each one:

1. ✔ vertebrates – Yes! Amphibians have backbones (they are vertebrates).
2. ✔ cold-blooded – Yes! Amphibians are ectothermic (their body temperature depends on the environment).
3. ✘ produce milk for babies – No! That describes mammals.
4. ✔ usually has webbed feet – Many amphibians like frogs and some salamanders have webbed feet for swimming.
5. ✔ mostly lays eggs – Yes! Most amphibians lay eggs in water.
6. ✔ breathes through their skin – Yes! Amphibians can absorb oxygen through their moist skin.
7. ✔ their skin is smooth and slimy – Yes! This is a key feature of amphibians (e.g., frogs, toads).
8. ✘ warm-blooded – No! They are cold-blooded.
9. ✘ has feathers and wings – No! That describes birds.

✔ Correct answers to circle:
- vertebrates
- cold-blooded
- usually has webbed feet
- mostly lays eggs
- breathes through their skin
- their skin is smooth and slimy

🔹 Part 2: Circle the animals that are amphibians

We are shown six animals:

1. 🐸 Toad – YES, it's an amphibian (a type of frog).
2. 🦎 Lizard – NO, it's a reptile.
3. 🦆 Duck – NO, it's a bird.
4. 🦈 Shark – NO, it's a fish.
5. 🐸 Frog – YES, definitely an amphibian.
6. 🦉 Salamander – YES, this is an amphibian (the yellow one looks like a newt or salamander).

✔ Animals that are amphibians:
- Toad
- Frog
- Salamander

✔ Final Answers:

#### Words that describe amphibians:
- vertebrates
- cold-blooded
- usually has webbed feet
- mostly lays eggs
- breathes through their skin
- their skin is smooth and slimy

#### Animals that are amphibians:
- Toad
- Frog
- Salamander

> 💡 Note: Lizards, ducks, and sharks are not amphibians — they belong to reptiles, birds, and fish respectively.
