Translation of "'stoat'" in Spanish

A stoat is as cute an animal as it is deadly.

Un armiño es un animal tanto bonito como fatal.

Unlike 'weasel', the Proto-Germanic ancestor of the word 'stoat' has not been established.

A diferencia de "comadreja", el antepasado proto-germánico de la palabra 'armiño' no se ha establecido.

Can you tell a stoat and a weasel apart just by looking at them?

¿Puedes distinguir a un armiño y a una comadreja solo con mirarlos?
