Study Notes

Groups of Amphibians

Three primary groups: salamanders, frogs and toads (anurans), and caecilians.

Tetrapod Requirements

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

Metamorphosis

Metamorphosis is the process where an immature hatchling undergoes transformation to become an adult, resembling other members of the same species.

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.
