A NUMBER of invertebrate animals possess blood pigments which are generally assumed to be respiratory, although only in a few instances has a respiratory function been demonstrated experimentally. For terms and use, please refer to our Terms and Conditions 1. This is the case at air saturation of the water and at oxygen concentrations below air saturation both at 10 and 17 degrees C. 3. Footnotes. 2. 1.The oxygen consumption of Sabella decreases soon after the concentration of dissolved oxygen in the sea water falls below the value corresponding to air saturation both at 10 and 17° C. Above air saturation at 17° C there is no significant rise in oxygen consumption. The Society’s fundamental purpose, reflected in its founding Charters of the 1660s, is to recognise, promote, and support excellence in science and to encourage the development and use of science for the benefit of humanity.

The Society has played a part in some of the most fundamental, significant, and life-changing discoveries in scientific history and Royal Society scientists continue to make outstanding contributions to science in many research areas. It follows that chlorocruorin functions as an oxygen carrier in Sabella at all temperatures and oxygen pressures to which the animals are subjected in nature. A NUMBER of invertebrate animals possess blood pigments which are generally assumed to be respiratory, although only in a few instances has a respiratory function … Chlorocruorin is an oxygen-binding hemeprotein present in the blood plasma of many annelids, particularly certain marine polychaetes.

It follows that chlorocruorin functions as an oxygen carrier in Sabella at all temperatures and oxygen pressures to which the animals are subjected in nature. As such, it may contain errors.

The oxygen consumption of Sabella whose chlorocruorin has been converted to carboxychlorocruorin is lower than that of normal worms. There are four major classifications of respiratory pigment: hemoglobin, hemocyanin, chlorocruorin, and hemerythrin. The fall in oxygen consumption of the animals after treatment with carbon monoxide is not due to an action of the latter on cell enzymes. The oxygen consumption of Sabella decreases soon after the concentration of dissolved oxygen in the sea water falls below the value corresponding to air saturation both at 10 and 17 degrees C. Above air saturation at 17 degrees C there is no significant rise in oxygen consumption. The oxygen consumption of Sabella whose chlorocruorin has been converted to carboxychlorocruorin is lower than that of normal worms. If chlorocruorin does act as an oxygen carrier, it may be that the pigment does not function when a worm is in air-saturated water, but only comes into action in water deficient in oxygen, the amount of oxygen in simple solution in the worm's blood being sufficient for its needs in air-saturated water.
