Sirens

Depicted as humans with the lower body of a dolphin, sirens are supposedly demonic in origin. Their hands are webbed and their skin thicker than that of humans. They have thick hair in green or red color and their eyes are always black.

Sirens mostly use wooden tools and live in shallow seas where they construct simple habitats from flotsam. Normally they live in small family groups of 2 to 8 individuals. While living in the sea they need beaches for birthing their young and hence they are known to most sailors and seafarers. Sirens often avoid contact with humans and, as they are sometimes mistaken for castaways, this has given them a reputation for trying to lure sailors ashore. Sirens can live as long as humans although it is rare for them to become older than 50. Sirens have their own language known as Nautilian but can sometimes speak a human tongue as well.
