Solution
The correct option is D Molluscs
- Haemocyanin and hemoglobin are respiratory proteins found in animal’s blood.
- Haemocyanin contains copper while hemoglobin contains iron. Hence the blood of animals with hemocyanin has a blue color instead of red.
- Most molluscs and arthropods contain hemocyanin, such as the horseshoe crab and the giant octopus.
- Haemocyanin is better than hemoglobin in lower oxygen environments like the bottom of certain oceans/seas.
- Annelids have hemoglobin, hemerythrin and chlorocruorin as blood pigments while echinoderms often lack any pigments.
