Water Person (Super Friends)

The Water People are a sapient, spacefaring species of aquatic humanoids from a world in the constellation of Sagittarius. Like Earth, about three quarters of their homeworld is covered in water.

Biology
The Water People are aquatic humanoids with pale skin, almond-shaped green eyes and a pair of small nostrils. They have webbed four-fingered hands and feet. Long pink hair is also present in some females. They can swim at over 40 mph (~ 64.3 km/h) and dive over two thousand feet in depth (609.6 m).

Culture and society
Water People are a friendly species which prefer to avoid confrontation. They travel through space in ships with numerous families on board. For fuel they use silicon, which they can extract directly from sea water. As an aquatic species, they haven't yet developed the means to obtain purified silicon from sand. Their vehicles use jet propulsion for moving underwater, and mechanical legs for traversing land. The Water People consider these more efficient than propellers and wheels, respectively.
