Namib wheeling spiders ("Carparachne spp."), found in the Namib desert, will actively roll down sand dunes. This action can be used to successfully escape predators such as the "Pompilidae" tarantula wasps, which lay their eggs in a paralyzed spider for their larvae to feed on when they hatch. The spiders flip their body sideways and then cartwheel over their bent legs. The rotation is fast, the golden wheel spider ("Carparachne aureoflava") moving up to 20 revolutions per second, moving the spider at 1 metre per second.
