Bullfrogs and frogs are not the same, the difference is: family difference, body size difference, skin difference, call difference.

Family difference: Bullfrogs and frogs are two different amphibians, which can be clearly seen from the different categories to which they belong. The bullfrog belongs to the genus Bullfrog in the order Anuraptilidae, but the frog belongs to the genus Tiger Frog in the order Anuraptilidae, and its scientific name is also called "Tiger Frog".

Difference in size: The difference in size between bullfrogs and frogs is a very obvious one. Bullfrogs are larger, ranging from 7-17 centimeters in length, and some can even reach 20 centimeters and above. The frogs are smaller, with their lengths ranging from 6-12 centimeters.

Skin Difference: There is also a difference in the smoothness of the skin between bullfrogs and frogs. The surface of the bullfrog's skin is relatively smooth, but the skin of the frog is rougher, which can be observed more clearly when you look at it.

Difference in origin: The origin of bullfrogs and frogs is different. Bullfrogs are native to North America, but frogs are native to many countries in Asia, such as China, Burma, Thailand, and Vietnam.

Call Difference: Bullfrogs have a prominent feature that their call is very loud, like the call of a cow, which is why they are named "bullfrogs", while pheasants do not have a call as loud as bullfrogs.
