Octopus' blue blood allows them to rule the waves

Summary:
Worldwide colonization by octopods is in their blood. They manage to survive temperature habitats ranging from as low as -1.8°C to more than 30°C due to their ability to keep supplying oxygen to their body tissues. A new study shows that a blue colored pigment, hemocyanin, in their blood, responsible for oxygen transport, crucially allows octopods to live in freezing temperatures.

Worldwide colonization by octopods is in their blood. They manage to survive temperature habitats ranging from as low as -1.8°C to more than 30°C due to their ability to keep supplying oxygen to their body tissues. A new study, to be presented at the Society for Experimental Biology meeting on July 5, shows that a blue colored pigment, hemocyanin, in their blood, responsible for oxygen transport, crucially allows octopods to live in freezing temperatures.

Research by Michael Oellermann, Hans Pφrtner and Felix Mark at the Alfred Wegener Institute for Polar and Marine Research in Germany, looked at how octopods are able to supply oxygen to tissues in freezing temperatures. The researchers compared the properties of blood pigment haemocyanin, responsible for oxygen transport, of Antarctic, Temperate and Warm-Adapted octopods.

The researchers found that the forms of haemocyanin of the Antarctic octopod Pareledone charcoti, are genetically and functionally different from the temperate and warmer climate octopods, facilitating oxygen release at sub-zero temperatures.

Michael Oellermann said: "Octopods are mainly local non-migratory species that move by crawling and have only short life stages in which they inhabit the water column. They are therefore mostly unable to migrate away from or escape "bad" environmental conditions, which exposes them to higher adaptive pressure to deal with these conditions. Our finding shows a crucial physiological adaption in cold environments that allows octopods to sustain an aerobic life."
