Does the sucker of octopus need to be removed?
Eating octopus does not need to remove its sucker, but it must be thoroughly cleaned to remove the dirty things stuck on the sucker. The parts that octopus can't eat are:

1, internal organs: The internal organs of octopus are located in the head, including stomach, intestine and other internal organs, and contain more toxic substances such as sediment, heavy metals, bacteria and feces. If you don't clean it, it will not only taste bad, but also consume too many toxic substances for a long time, which is not good for your health.

2, teeth: although the octopus's body is soft, but the octopus's teeth are very sharp, in the middle of the glass sucker. If you don't remove it and eat it again, it will affect the taste and even knock your teeth, causing adverse consequences.

3, black film: there is a black film on the octopus skin, which will be very embarrassing to eat, which will greatly affect the taste. It is recommended to remove it before eating.
