The blood of most species of serpulid and sabellid worms contains the oxygen-binding pigment chlorocruorin.
2.
The blood of " S . vermicularis " contains the oxygen-binding pigment chlorocruorin.
3.
Chlorocruorin is an kDa myoglobin-like subunits arranged in a giant complex with a total weight exceeding 3600kDa.
4.
The most common of these is haemoglobin, but some groups have haemerythrin or the green-coloured chlorocruorin, instead.
5.
The ratio of plasma hemoglobin to chlorocruorin is high in younger individuals, but this ratio reverses as the animal matures.
6.
;Chlorocruorin : Found in many annelids, it is very similar to erythrocruorin, but the heme group is significantly different in structure.
7.
The biochemistry of the blood of " Serpula " is especially unusual in that the blood contains not only hemoglobin, but also chlorocruorin.
8.
Chlorocruorin ( as the larger carrier erythrocruorin ) is an oxygen-binding hemeprotein present in the blood plasma of many annelids, particularly certain marine polychaetes.
9.
While all sabellids and serpulids employ chlorocruorin as an oxygen transport macromolecule, " Serpula " is the only genus that appears to possess both hemoglobin as well as chlorocruorin.
