Hello All,
At TONMOCon, Dr. Gilly and I had a few moments to discuss ammoniaism in squid and about the lifestyle of Dosidicus gigas and possible oxygenation issues. What I am wondering is how much research has been done on how deep water squid and octos survive hypoxic conditions. I know that their metabolism is low, and that the overall O2 affinity of hemocyanin is low, but what about overall respiratory efficiency? Does cutaneous respiration occur in the mantle or anywhere else? What about the use of CO2 "Carbon Sinks", to handle CO2 buildup? In what way does cephalopod tissue deal with CO2 buildup (analogous to the mammalian use of lactic acid)?
Just asking questions,
John
