Here on the Black Sea in Romania people are eating a shellfish called in Romanian "rapane" which they translate as "oyster". But they are elongated spiral shells which to me look nothing like the chunky flattish oyster shells in Australia. Besides which there is another Romanian word "stridie" for oyster and I can't find "rapane" in my print dictionary or any online dictionary but I can find some pictures with Google Images.

So, if I take photos of the shells and the food and ask what it's called in English would that be an acceptable question for this site?

EDIT

I couldn't find a question where this was done but there is this question asking to identify a food from a vague description and people asked for a photo to be added but none was.
