What external feature does the salamander have that the frog does not?Group of answer choicesgillslungsfinseyes

To answer the question regarding the external features of salamanders and frogs, we need to consider the biological characteristics of both animals.

Key External Features Comparison

1. Gills: Salamanders, especially in their larval stage, typically have external gills that they use for breathing. Frogs do not have external gills; instead, they develop lungs as adults.

2. Lungs: Both frogs and adult salamanders possess lungs, but this feature is not unique to salamanders.

3. Fins: Fins are typically associated with fish and are not common in salamanders or frogs. Thus, it does not apply.

4. Eyes: Both frogs and salamanders have eyes, so this characteristic is not external to one species alone.

Conclusion

The external feature that salamanders have which frogs do not are gills. Frogs typically do not have gills beyond their tadpole stage, transitioning to lungs for respiration as adults.

Final Answer

Gills are the external feature that salamanders have that frogs do not.
