"frog"的定义和意义

What is a "frog"?

A frog is an amphibian characterized by its slender body, long hind legs, webbed feet, and smooth, moist skin. It is a highly adaptable creature that inhabits a wide range of environments, including forests, wetlands, and gardens. Frogs are known for their ability to jump and swim, making them agile both on land and in water. They undergo a remarkable life cycle, starting as aquatic tadpoles and undergoing metamorphosis to become fully developed frogs. Frogs are often associated with their distinctive croaking calls, which they use to communicate and attract mates. They play a vital role in ecosystems as both predator and prey, helping to control insect populations and serving as a food source for other animals.
