"@" has a lot of interesting names - monkey, herring, pig's tail, strudel, mouse, elephant's trunk, and "arroba" (a unit of weight, like a bushel).

[gvx]

Yeah, in Dutch it's "apenstaartje" (little monkey's tail), although the last decades, it's becoming far more common to use the English "at".

[froh]

it's "Klammeraffe" in German, spider monkey, and figuratively a small monkey clinging to / clasping someone or something.

It's "zavináč" in Czech -- pickled herring. If you buy them in a jar, they're rolled up, looking a lot like that symbol.

I kept a collection of names for @ on my first website: https://web.archive.org/web/19981202002949/www.student.nada....

What languages or cultures or regions use this form?

[HillRat]

It's particularly popular in Yendor, I believe.

[anyfoo]

Spread from there to Ancardia and Moria as well, though.

In the 90s/00s it was often referred to as 'miukumauku' in Finnish, roughly translates as 'meowmeow', as in the sound a cat makes, since it somewhat looks like a sleeping cat.

[kotborealis]

In Russian, it's usually called `dog`. No idea why.

[abudabi123]

A dog will always perform a certain spiral inwards walk pattern before it comes to rest on bedding.

[joosters]

I forget the exact details, but I've seen it called a snail in some programming language or other - I remember getting an error message along the lines of 'unexpected snail at line x'! I wish I could recall what language it was - perhaps something verilog related?

[gpas]

In italian we call it "chiocciola", which translates to snail.
