The blood of which creature among the following does not contain haemoglobin?

Option 4 : Cockroach

The correct answer is option 4 i.e Cockroach

• The blood of Earthworm is red coloured due to the presence of respiratory pigment haemoglobin. 
• Fish blood cells have the presence of multiple forms of haemoglobin, called isohaemoglobins, which have different oxygen binding properties.
• Frogs, snakes, and lizards all have haemoglobin as the respiratory pigment in their blood, and haemoglobin is generally that rich red colour. So these all have red blood.
• The blood of the cockroaches does not have haemoglobin, which is what gives human blood the red colour. Hence option 4 is correct.
