Bullfrog and frog are both frogs, but they are different.

Frog is a kind of frog, belonging to Amphibia and Ranunculaceae. Yellow-green or dark green with black spots on the back. The head is slightly triangular, and the eyes are round and prominent, which can quickly find flying insects. The mouth is big, the root of the tongue is attached to the front of the mandible, and the tip of the tongue is forked, which can suddenly turn out the mouth to prey on pests. There are semi-aquatic organisms all over China. We often eat frogs.

The bullfrog page also belongs to Amphibia, Ranidae. Bullfrog, called bullfrog, is one of the larger frogs, because it has a loud voice, like an ox. The back of female frog is brown, and that of male frog is dark green. Male frogs croak and scream, and smell like Niu Jiao, hence the name. Eat insects, small fish, etc. Of course, bullfrogs can also eat.

But frogs will be a little more expensive than bullfrogs and more delicious.
