No, there aren’t giant spiders on Mars

Mars Orbiter Spies Alien Ice ‘Spiders’. They are, however, unique erosion patterns not found on Earth caused by the sublimation of dry ice during the Martian spring.

Carbon dioxide ice on Mars does not melt into a liquid state; it bypasses the liquid phase and sublimates straight from a solid into a vapor. This seasonal process therefore creates its own type of erosion on the Martian landscape.

“This particular example shows eroded channels filled with bright ice, in contrast to the muted red of the underlying ground,” writes Hansen. “In the summer the ice will disappear into the atmosphere, and we will see just the channels of ghostly spiders carved in the surface.” [Amazing Mars Photos by MRO]
