“…Mc Keown et al. (2023b) conducted a study over three spider sites containing fat and thin spiders, measuring the diameters of the spiders and their central pits, as well as the number of branches (over 1,000 per spider for starburst spiders) using the Strahler (1952) stream order method for 112 spiders. Informed by their previous experiments of spider development on the small‐scale (L. Mc Keown et al., 2021), they suggested that the central pit of spiders corresponded to the size of the original vent responsible for their formation.…”

Araneiforms are some of the most intriguing surface expressions found on another planet in that they are active today, have no direct Terrestrial analog, and represent a formation process that is unlike anything seen on Earth. They are defined as converging systems of branching troughs exhibiting fractal properties and comprise a variety of different types based on observed activity and location. These include (a) the original "spiders" (e.g., C. J. Hansen et al., 2010;Piqueux et al., 2003), which are large (up to 1 km in diameter), dendritic, often radial negative topography features restricted to the high south polar latitudes; (b) sand furrows (M. C. Bourke, 2013; M. C. Bourke & Cranford, 2011), which are up to 50 m in length and extend along dune slopes in both hemispheres over a season (then disappearing), and (c) dendritic troughs (G. Portyankina et al., 2019), which have been observed to form and grow interannually on loosely consolidated inter-dune material. All of these features are proposed to be formed by some variant of a "geyser" (non-geothermal) process known as the Kieffer model (Kieffer et al., 2006). This model postulates that insolation penetrating through translucent CO 2 ice during spring yields basal sublimation and produces energetic jets. The process can leave fans and spots of dark albedo fines strewn across the ice surface, having scoured the substrate to form dendritic patterns (Kieffer et al., 2006;Piqueux et al., 2003). Fans and spots are identified in the locales of all of these features in spring , but only both furrows (M. C. Bourke, 2013) and dendritic troughs (G. Portyankina et al., 2017) have been observed to form today.
