Nuu

The Nuu are a pacifist race hailing from their homeworld of the same name. Their world is largely aquatic and they were once entirely aquatic lifeforms, but among many evolutionary changes they incurred due to actively working to coexist with other sentient species, they became amphibious.

Physiology
Nuu can immediately be spotted as most resembling fish, though they have a high degree of aesthetic differences between them. Standing at the same height as humans on average, they're extremely frail and prone to dehydration when living on land even if they can manage to do so for extended periods of time. Their brains and by extension nervous systems are more complex than that of other races, which seems to be the source of their vast intellect; they're known for their advanced technologies but have also never put their science to work making any kind of weapon. Their skin is made of soft scales which lend themselves to streamlining underwater and they come in a wide variety of colors - Various shades of black, blue or purple, sometimes even extending into reds or pinks or white. Many have a sort of pattern to their skin consisting of more than one color. They have webbed hands and feet that lend themselves to swimming and vestigial fins that vary in length and rigidity, making their individuality even greater. Their eyes are considered somewhat anomalous among other races, as this is one feature which doesn't seem to change - Every Nuu has large single colored eyes, entirely black and often very moist. To some it's somewhat uncomfortable to look at, though many report sensing a vaguely endearing empathy in their gaze.

Lifespan
Birth is practically sacred among the Nuu, due to both the nature of their reproduction and the intense desire to celebrate and preserve life. They are non-mammalian and breed through clusters of eggs, which themselves take a few years to hatch. Their actual lifespan is comparable to elves and their technological superiority means high survival rate among newborns - But because of this, they are deliberately careful in conducting reproduction and it is treated as a grand spiritual event.
