Haemolymph is observed in Arthropods. Hemolymph is a fluid in the body cavities and tissues of invertebrates, in arthropods functioning as blood and in some other arthropods functioning as blood and in some other invertebrates functioning as lymph.
Haemolymph is the fluid in teh circulatory system of arthropods i.e., archnids, crustaceans and insects. Haemolymph fills all the interior (Hacmocoell) of the animal’s body and surround all cells. It contains hemocyanin, a copper based protein that turns blue in color when oxygenated, instead of iron-based blue in color when oxtgneated, instead of iron-based haemoglobin in red blood cells found in vertebrates, Thus, haemolymph gives a green- blue color color to their blood.
