Flailx are oddball "fish" that photosynthesize their oxygen from the sun, severely limiting the nautical areas they may call home. However, flailx are extremely adept at holding their breath for long periods of time (sometimes for days!) and will venture into the deep sea to frolick along the seafloor alongside other schools of fish. They will, however, frequently return to the surface for more air and to re-warm their bodies in the sun after spending much time submerged. It is theorized that the flailx are a "reverse-evolution" of land mammals turned nautical, and that ancient flailx had long, spider-like legs.
