Antarctic octopods are able to survive freezing weather, as low as -1 celsius, thanks to a blue pigment in its blood. But why? Researcher from the Alfred Wegener Institute for Polar and Marine Research in Germany studied how the pigment, hemocyanin, can keep octopods' oxygen moving, despite the sub-zero temperatures.
How are the octopods (Pareledone charcoti) genetically different? And why? Kim Horcher and Cara Santa Maria discuss the blue blood.
