Flying fish in Cele Trei Creaturi live around the edges of the world, particularly around the seven World Waterfalls. The Athletics God is a flying fish. While most live in the water and fly only to catch bugs, thus retaining all of their swimming capabilities (pics 1,6), the flying fish farther inland are more specialized for various terrestrial niches (pics 2, 4, 5). Some of the most inland flying fish are incapable of swimming properly, although they still need water to lay their eggs and hatch their fry.
Some are bred as pets (pic 3). These pet flying fish are not known for their stellar flying abilities, or intelligence.
