And yet, even in this bitter uninviting world of cold shadows, a myriad of peculiar creatures have made their homes, dramatically adapting their anatomy, behaviours and physiologies in order to cope with the challenge of living here. In this film, we’ll take a look at the unique ways in which these otherworldly creatures have adapted to thrive as masters of the deep dark sea.
