Images of Titan
If you are asked about Titan, you can boast of your astronomical knowledge, remembering that Titan is the only cosmic body in the solar system with proven stable arrays of liquid on the surface.
You will nod approvingly and may wonder where on Titan are these liquid arrays. If you inadvertently say that these distinct black spots on the equator of pixel1 are the hydrocarbon seas of Titan, you will be laughed at.

These areas are mostly dry, they could well ride a wheeled Titan Rover. And those very hydrocarbon seas are located much above the equatorial black spots, near the north pole - pixelated2.

>> There are dark regions similar in size to Xanadu, encircling the satellite along the equator, which were initially identified as methane seas. Radar studies, however, have shown that the dark equatorial regions are almost universally covered by long parallel rows of dunes stretched in the direction of prevailing winds (west to east) for hundreds of kilometers - so-called "cat scratches."

>> The dark color of the lowlands is explained by the accumulation of particles of hydrocarbon “dust” falling from the upper layers of the atmosphere, washed away by methane rains from elevations and brought to the equatorial regions by winds. Dust can be mixed with ice sand.
