haemocyanin การใช้

The majority of gastropods have haemolymph containing the respiratory pigment haemocyanin.
Malacostraca have haemocyanin as the oxygen-carrying pigment, while copepods, ostracods, barnacles and branchiopods have haemoglobins.
In the freshwater Planorbid snails, however, the haemocyanin is replaced by haemoglobin, and thus their haemolymph is red rather than blue.
In scorpions and some spiders, however, the blood contains haemocyanin, a copper-based pigment with a similar function to haemoglobin in vertebrates.
In a severe infection, the ability of the lobster's blood pigment haemocyanin to carry oxygen may be reduced by up to 50 %.
