Homebrew Fish-men Species Details

Fish-men have gills near their necks, which only work when they are in water. On land, they can breathe with their lungs like humans do. However, their gills cannot breathe in air, like a normal fish cannot breathe in air through their gills.

Even though fish-men are part fish (or at least closer to fish biologically than human) and have been considered such by prejudiced humans in the past, they are still mammals and give birth to live young. Fish-men are also able to modulate the sounds that they make enabling them to speak in the same language as humans, yet at least one fish-man, Jinbe, has the ability to talk to other animals such as whales showing that a fish-man's larynx appears to be far more adaptable and capable of more than a human's. There are many merfolk who bear physical traits normally unique to fish-men, like Den's webbed hands and Shyarly's fangs. Furthermore, fish-men can sometimes demonstrate powers usually unique to merfolk, such as Jinbe's ability to communicate with whale sharks.

Even with merfolk and fish-men in the same immediate family, the primary species (merfolk or fish-men), subspecies (type of fish) and appearances may differ. The reason is that they still carry the genes of their ancestors, so the species is not determined only by the parents, but it can be any one type among all the species of the ancestors. Humans, fish-men, and merfolk have the same blood types, and can share if the types match.

The fish-men's subspecies have many variations, just like merfolk, being many types of fishes. So far, with the exception of the half fish-man Dellinger (whose fish traits are that of the Fighting Fish), all known fish-men fish-halfs are based on real-life fish species and not on any of Oda's made up species. Also, their size may vary greatly, with Wadatsumi being a fish-man the size surpassing that of an average giant. Unlike merfolk, fish-men eat meat, including fish, although whether this is a dietary advantage or just custom is unknown.
