Hearing in Penguins

Pinguine sind perfekt angepasst an ein Leben im Meer und an Land. Auch wenn diese beliebte Tiergruppe sehr gut erforscht ist, gibt es dennoch Wissenslücken. Zum Thema „Hören von Pinguinen“ weiß man bisher fast gar nichts. Wissenschaftler*Innen wollen dieses interessante Themenfeld nun näher untersuchen.
