- Definition: The term “amphibious” describes organisms or vehicles that can operate both on land and in water. In biology, it refers to animals, typically vertebrates, which can live and function in both aquatic and terrestrial environments. In a broader sense, it’s also used to describe vehicles, such as certain military craft, designed for operation on both land and water.
- Etymology and Origin: “Amphibious” is derived from the Greek word “amphíbios,” meaning “living a double life.” This is composed of “amphí” (on both sides, or double) and “bios” (life). The term came into English in the early 17th century, capturing the essence of living or operating in two different environments.
