The most important question about this, however, is undoubtedly that their blood resembles ours. why he is not in the red.

The answer is very simple: lobsters and some other arthropods use oxygen to transport oxygen. They use hemocyanin instead of hemoglobin. While hemoglobin contains iron, hemocyanin contains copper. This is where the whole issue really begins.

Copper turns a bluish color when combined with oxygen.

Therefore animals that contain hemocyanin blood appears blue when it carries oxygen. When oxygen binds, hemocyanin turns blue; when oxygen is not bound, it is colorless.
