They all belong to the animal kingdom, Chordata, Amphibia and Anura. Anurak is commonly known as frog.

Frog (Amphibia Anura)

3. Common black-spotted frogs:

As for the different names, I looked at Wikipedia and Baidu Encyclopedia, and I didn't agree with several names.

Wikipedia says "Toad is a general term for frogs and toads", "Toad is commonly known as toad" and "Anura mainly includes frogs and toads. There is no strict difference between these two types of animals, and some families have both. "

Baidu wrote "Toad, also called Toad Hama" and "Ranunculaceae Anura collectively referred to as frog"

5. As for toxins:

"Many frogs have slightly poisonous toad venom on their surfaces, which makes them unpopular with predators. Most toads, on the other hand, have large poison-producing glands, called parotid glands, which are mainly located at the back of the eyes or other parts of the body. These glands can secrete different toxins or mucus, making their skin slippery and unpalatable.

If they can feel unhappy immediately, the hunter will stop hunting and let them escape. If the effect takes a long time to take effect, it can also reduce the chance of the hunter hunting again next time. Pathogenic frogs are often covered with bright colors, indicating that they are not suitable for eating. This adaptive strategy is called vigilance.

The well-known poisonous frog is the poison dart frog. Many primitive tribes used to put its venom on arrows to shoot their prey.

6. Generally speaking, we usually tell the difference in our life. Generally speaking, the green one with smooth skin is called frog, the gray one is black, and the skin is called toad.

7. Don't touch frogs and toads easily, especially brightly colored ones. Ordinary people have no ability to distinguish between poisonous and nontoxic frog species.
