Explanation:

Each animal was matched to its class based on its physical characteristics and reproductive traits as described in the worksheet. For example:
- Mammals are identified by having hair/fur, giving birth to live young, and being warm-blooded.
- Birds have feathers, lay eggs, and are warm-blooded.
- Reptiles have scales, lay eggs, and are cold-blooded.
- Amphibians have skin (not scales), lay eggs, and can breathe through lungs or gills.
- Fish have scales, lay eggs, and use gills for breathing.

This classification helps students understand the diversity of vertebrates and their distinguishing features.
