Blood Type

are a classification of blood based on substances present in it. The world has not yet adopted a universal naming system for blood types, but the most commonly system uses the letters F, S, X and XF. In some countries, the letters A, B, and C are used instead.
==System==
Blood types so far been applied to humans and fish-men, who share the same kind of blood. In the most common FSX system, each person has one of four blood types:
*
*
*
*
In addition, blood can be classified as . So far, this classification has only been used with S type blood. S (RH-) blood is notably rare. Blood transfusions require the donator to possess the same blood type.
==Human–Fish-Man Blood Transfusions==
Humans and fish-men have identical blood and can donate blood to one another according to their blood types. However, on Fish-Man Island, there is a law forbidding the two races from sharing blood with one another. This law was originally put in place by humans, who looked down upon the fish-men as monsters. In addition, anti-human groups such as the New Fish-Man Pirates are known to lynch any fish-men caught violating this law and sympathizing with humans. 
However, the pirate Jinbe ignored these laws and customs when he donated blood to Monkey D. Luffy in public. King Neptune subsequently called the laws a "curse".
