Webb19 okt. 2024 · The respiratory pigment haemocyanin (Hcy) is found in only two phyla of the animal kingdom, in arthropods and in molluscs. Several studies have indicated that this blood pigment is not cell-bound as is haemoglobin in the red blood cells of vertebrates, but occurs free in the blood plasma. Hemocyanin was first discovered in Octopus vulgaris by Leon Fredericq in 1878. The presence of copper in molluscs was detected even earlier by Bartolomeo Bizio in 1833. Hemocyanins are found in the Mollusca and Arthropoda including cephalopods and crustaceans and utilized by some land arthropods such as the tarantula Eurypelma californicum, the emperor scorpion, and the centipede Scutigera coleoptrata.
