Canned Russian Herring with teeth (Source)
In Russia you don’t eat canned fish, the canned fish eat you! The can pictured here is supposed to contain Atlantic Herring however it looks more like a piranha or snake head to me. Alternatively it could be a wolf herring which is also found in the Atlantic. If there are any fish experts out there that can help identify it please let us know. Whatever it is, it deserves a place in the bizarrefood blog.
