Reef Devils are a sapient race in the Big Blue. They are an amphibious species native to Cerulea that split and evolved apart from Tritonids over hundreds of years. This was due the Change exposure from living in their home, Devils' Reef, which is located within a Change-field.
Reef Devils possess fish- and shark-like features, such as darker, rounder eyes, gills (despite already being amphibious) and several rows of even pointier teeth than Tritonids, as well as shark-like fins on their backs and elbows. They usually have indigo skin that fades to a pinkish purple at the extremities, such as around the edges of their fins, their noses and ears, elbows and knees, and nails.
Their natural disposition is jittery and distrustful, and are usually non-verbal in unfamiliar environments, and they are therefore viewed as hostile or gremlin-like by others. Though regarded by many as insane and volatile, Reef Devils can be crafty, intelligent and capable of just as much creativity and complex thought as any other species.
Reef Devils speak a dialect of Tritonid called Reefian, which preserves conservative features that has been lost in other branches of the language. Some Reef Devils also speak standard Tritonid -- or, alternatively, Common -- but it is often broken or sounds archaic due to the influence of Reefian on their speech.
