What animal has black blood?

In fact, blood is made up of four components: red blood cells, white blood cells, platelets and plasma.
Is black blood real?
It owes its color to hemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated). Human blood is never blue.

Do snails have blood?
Snails consist of blood to 20 to 50 %, the sea hare’s (Aplysia) body weight is about 75 % blood. Most snails’ blood pigment is haemocyanin. Contrary to haemoglobin, used by vertebrates, haemocyanin works on a complex with copper as oxygen binding atom. … Snails’ circulation basically is open.
What animal has 800 stomachs?
