Translation of "Shuddered" in Portuguese

My wife shuddered at the sight of a one-eyed cat.

Minha mulher tremeu ao ver um gato caolho.

The fleet was on mid ocean; land no more / was visible, naught else above, before / but sky and sea, when overhead did loom / a storm-cloud, black as heaven itself, that bore / dark night and wintry tempest in its womb, / and all the waves grew rough and shuddered with the gloom.

Quando os navios já se encontram no alto mar, / não mais restando terra alguma à vista – / céu e mar, mar e céu por toda a parte – / vêm sobre nós pesados nimbos, transportando / treva e tormenta, e o mar se encrespa assustador.
