Let’s go step by step through each sentence and decide whether it’s about amphibians (A), reptiles (R), or both (B).
---
1. They are cold-blooded.
→ Both amphibians and reptiles are cold-blooded (they can’t control their body temperature like we do).
✔ Answer: B
---
2. They have scales.
→ Reptiles have dry, scaly skin. Amphibians have smooth, moist skin — no scales.
✔ Answer: R
---
3. They breathe air.
→ Adult amphibians breathe air with lungs (some also use skin). Reptiles always breathe air with lungs. So both do!
✔ Answer: B
*(Note: Even though baby amphibians may use gills, the statement says “they breathe air” — which is true for adults of both groups.)*
---
4. They lay eggs.
→ Most amphibians and most reptiles lay eggs. Some reptiles give live birth, but generally, egg-laying is common to both. The worksheet likely expects this as a shared trait.
✔ Answer: B
*(Exception note: A few reptiles like some snakes/lizards give live birth, and a few amphibians too — but for school level, “they lay eggs” = both.)*
---
5. They have moist smooth skin.
→ This is only true for amphibians. Reptiles have dry, scaly skin.
✔ Answer: A
---
6. They live the first part of their lives in the water and the last part on land.
→ This describes amphibians (like frogs: tadpoles in water, adults on land). Reptiles usually hatch on land and stay on land (except sea turtles, etc., but they don’t change habitat like amphibians).
✔ Answer: A
---
7. They breathe with lungs and gills.
→ Only amphibians do this — babies (tadpoles) use gills, adults use lungs (and sometimes skin). Reptiles never use gills.
✔ Answer: A
---
8. They have four or no legs.
→ Most amphibians have 4 legs (frogs, salamanders). Some reptiles have 4 legs (lizards, crocodiles), some have none (snakes). So both groups include animals with 4 legs OR no legs.
✔ Answer: B
*(Example: Frog = 4 legs; Snake = 0 legs → so “four or no legs” applies to both groups overall.)*

They are cold-blooded. →
B
They have scales. →
R
They breathe air. →
B
They lay eggs. →
B
They have moist smooth skin. →
A
They live the first part of their lives in the water and the last part on land. →
A
They breathe with lungs and gills. →
A
They have four or no legs. →
B
