A hot land-sea planet with an ocean that is not made of water would likely have a unique and alien landscape. The land portion of the planet may be a vast expanse of rocky terrain with sparse vegetation and extreme temperatures, while the "ocean" would be a thick, viscous substance, perhaps a liquid metal or molten lava. The sky above would be tinged with a reddish hue from the intense heat and the atmosphere would be filled with toxic gases. The interactions between the land and sea on this planet would be violent and dynamic, with frequent volcanic eruptions and seismic activity shaping the landscape. The creatures that have evolved to inhabit this harsh environment would be adapted to withstand extreme temperatures and pressures, with unique biology and behavior that allow them to thrive in such a harsh world. Overall, a hot land-sea planet with a non-water ocean would be a hostile and inhospitable place, filled with danger and mystery, and offering a stark contrast to the more familiar planets we know in our own solar system.
