Isn't this a squid? Why do my neighbors say that this one I bought is not squid at all? Today, I saw that there was a squid for sale, 15 pounds, and I bought two catties when I looked very fresh

Isn't this a squid? Why do my neighbors say that this one I bought is not squid at all?

Today I rushed to the gathering I saw that there is a sale of this squid, 15 pounds, I looked very fresh and bought two pounds, came back to the neighbor asked me what to buy, I said squid, a few people came to see and said that this I bought is not squid, how is this not squid, I have the impression that this is squid, like what iron plate squid sold at the food festival is not like this?

Everyone said, is this a squid?
