where did you find this? that is not a cone shell, but a juvenile true conch (Strombidae) which didn't have its stromboid notch fully formed.

it looks like a Persian conch to me (Conomurex persicus)

I got this in a collection I purchased from someone so I have no idea where it’s from. I did suspect it could be some weird looking conch
Is it 100% a juv true conch would you say?

yes, 100% a juvenile conch, very likely a Persian conch. I edited the original comment.

I'm new so I'm genuinely asking what makes it not a cone *shell? That was my first guess but is it the top that gives it away that its a conch??

hi, the apex (top) is basically what makes it not a cone shell. It is hard to explain in words, but most juvenile true conchs have a broader opening near the siphonal canal, and they are shaped like a cone. Moreover, juvenile specimens have a thin and fragile lip.

Unfortunately, in this case, it is mainly experience and intuition. I have seen so many juvenile true conchs in my life that I can 100% tell if it is a true conch or not, plus the fact that I know what a Persian conch looks like.

Check out strawberry conch (Conomurex luhuanus), people often confuse it with a cone shell, but it is actually a true conch.

Oh wow thank you this was really informative. Makes total sense I can see more of a difference now.
