The copper in their blood gives their blood a bluish tint. It is much like how iron in our blood causes our blood to be red. Haemoglobin is a red pigment in blood that makes the blood red when it comes out into oxygen (that why when we bleed, our blood is red.) some animals do not have haemoglobin in blood, for example LOBSTERS! So this is why their blood is blue.
Some crabs and lobsters.
Not necessarily. Crustaceans such as lobsters have blue blood. But vertebrates such as fish and whales have red blood.
There are many different kind of lobsters around the world. The color of lobsters is dependent on where they live and what they eat. Lobsters can be blue, red, yellow, yellow calico, two-toned, and black.
Mammalian blood is NOT blue.
A metal called aluminium.
Lobsters in the wild are generally mottled yellow, green, brown, and almost never red. The reason they turn red during cooking is that other pigmentations are broken down by heat, but the red pigments are not.
