In the German language there are some commonly used sayings with amphibians and reptiles.
"allen Unkenrufen zum Trotz" (despite the prophecy of doom / Unkenrufe=calls of Bombina)
"Sei kein Frosch" (don't be a coward / Frosch=frog)
"einen Frosch im Hals haben" (to have a frog in the throat)
"eine Kröte schlucken" (to swallow a bitter pil / Kröte=toad)
"ein paar Kröten" (a few bucks / Kröten=toads)
"Sie ist eine falsche Schlange" (she's a snake in the grass / Schlange=snake)
"Schlangenfrass" (awful meal)
I wonder if there are the same or similar expressions in other languages. Who can help?
