Sarustre, a Pelagic world with total ocean coverage

Gaian Type planet. Water covers 85 to 99% of the surface. Oceanic climate varies. Land life, if advanced, may be stunted due to a restriction of terrestrial biomes. The atmospheres may be oxygen rich due to photolysis of water vapour and other ocean-related factors. Some worlds have an oxygen content in excess of 90%. Some pelagic worlds have very thick atmospheres; worlds that have hot, high-pressure supercritical oceans are known as PelaVenusian worlds.

Temperate Pelagic worlds with deep oceans are known as BathyPelagic worlds; those with shallow oceans are called EuPelagic worlds. Worlds with icy oceans are given the PelagicGelidian Subtype designation.

    Largely arctic Gaian Type worlds. However, small and scattered continents will inspire great amounts of precipitation, leading to large polar caps and land glaciation. Only the equator of most worlds have a warm year around climate.
