Which sign is called 'monkey tail', 'puppy', 'snail', 'moon's ear' or 'pig's tail' in different languages?

Good to know, but wondering why there's a picture of a pickled rollmop herring?

ATS, In Czech we call it "zavináč". And the pickled rollmop herring is "zavináč" too. If you wonder why, check the rollmop shape from the side.

In Polish most people will call it "monkey" for reasons unknown.

ATS, I agree, but now I want to eat some pickled herring.

In Bosnia & Herzegovina it's called "ludo a", or "crazy a" translated in english.

In greek it's called "papaki", which means duckling.
