Do you have any idea which species that might be? You may need to delve into the depths of the internet to work it out, but it’ll be worth the effort. Have fun!

I’m just happy you got the clues without me saying what I incorrectly thought it was.
Usually I can narrow things down a bit, if not to a species, but looking at this one I couldn’t narrow it down even to Kingdom! Still, 7 inches long would be a big nut, so I’m leaning to the molluscan suggestions…
Think I may be wrong with my previous answer. Like peas in a pod, it could be a close shave.
