An online visit to a website such as Frog Life Cycle helps you identify the type of frog you have, and it provides colorful photos and descriptions. There are over 80 different types of frogs in the United States and over 4,000 types worldwide.
Frogs come in colors other than green. There are yellow, brown, orange, red and black frogs and ones with color combinations. The patterns vary from solid to vibrant patterns. Male frogs also make sounds, or calls, which range from dog-like barks, whistles and groans to bird-sounding chirps. Calls are used to attract females at mating time, mark territory and warn predators.
