Are the mini octopus in calarmari from the same creature as the actual calamari rings?

I just ordered calamari from an Italian restaurant. For the first time I noticed fully formed mini octopi fried up and included amongst the "regular" fried ring calamari pieces. I've never seen this before. Are they just teeny tiny little squid? Or are they a part of the squid that the rest of the calamari rings come from? Are they a separate food entirely?

Let me clarify-- I'm talking about things that look just like itty bitty little octopus. I'm just trying to figure out if they are smaller versions of what the actual calamari "rings" are made of.

The little octopus-looking fried bits are the tentacles or legs of smallish-squid. Calamari is the entire squid cut up into pieces and fried usually- the rings come from the head and body, and the octopus-looking legs are from the bottom of the squid.
