Amphibious in Context
The amphibious nature of frogs allows them to spend part of their lives in water and part on land. They typically begin life as aquatic tadpoles before developing the physical characteristics needed to live primarily on land. This ability to adapt to two different environments makes amphibious animals particularly interesting to biologists.

The term amphibious is also used for vehicles designed to travel on both land and water. For example, an amphibious vehicle can drive along a road and then enter a lake or river without requiring a different means of transportation. Such vehicles are useful in situations where conventional land or water transportation alone would be insufficient.
