Observed alpha-stat pH pattern for octopus haemolymph. The temperature dependent change of pH was determined for thawed Octopus pallidus haemolymph at 0°C, 10°C, and 20°C. Venous pH of the other species refer to freshly sampled and analysed haemolymph. pH were corrected to the free hydrogen ion scale by subtracting an experimentally determined offset of −0.136 (0.130-0.142, n = 87) pH units to account for the high ionic strength of cephalopod haemolymph [61]. Sources: Octopus pallidus, Pareledone sp., Adelieledone polymorpha (Strobel and Oellermann 2011, unpublished); Eledone moschata (Strobel and Mark 2010, unpublished); Octopus vulgaris [50,51].
