Answer:

The "at "symbol (@)seems to appear everywhere, and nobody even knows what to call it. In other languages it has specific nicknames:

• apenstaartje - Dutch for "monkey's tail"
• snabel - Danish for "elephant's trunk"
• kissanhnta - Finnish for "cat's tail"
• klammeraffe - German for "hanging monkey"
• papaki - Greek for "little duck"
• kukac - Hungarian for "worm"
• dalphaengi - Korean for "snail"
• grisehale - Norwegian for "pig's tail"
• sobachka - Russian for "little dog"

The rather interesting history of the symbol and a selection its potential origins is at the link.
