Tetrapod Requirements
- An animal must have four legs to be classified as a tetrapod.

Salamander Types
- Three categories of salamanders:
- Wholly terrestrial salamanders
- Wholly aquatic salamanders
- Amphibious salamanders
Anuran Classification
- Both toads and frogs fall under the group known as anurans.
Larval Stage
- The larval stage of a frog or toad is referred to as a tadpole.
Caecilian Visibility
- Caecilians are rarely seen as they are primarily burrowing or aquatic creatures.
Annuli
- Annuli are the skin folds or rings present on caecilians.
Supporting Amphibians
- Personal actions to aid amphibians could include:
- Creating amphibian-friendly areas in gardens
- Properly disposing of garbage
- Avoiding the release of non-native species into local ecosystems
- Documenting amphibian sightings in science journals to contribute to citizen science efforts.
