Translation of "Empinadas" in English

Destacam-se entre as ondas as cabeças / empinadas e as rubras e altas cristas; / o restante dos corpos volumosos / desliza em grandes arcos sobre o mar.

Their breasts erect they rear amid the deep, / their blood-red crests above the surface shine, / their hinder parts along the waters sweep, / trailed in huge coils and many a tortuous twine.
