The colour of blood is Red in colour due to the presence of Haemoglobin where the Haem is surrounded by 4 Iron molecules and this is well seen in Mammals but where as in Insects i.e Arthropods we can’t find this feature of blood being in red but instead colourless due to the absence of respiratory pigment in blood.
