A spider living in the Sahara Desert excavates its burrow by hauling out bundles of sand fastened with silken cords, while another carries sand balls in a ‘basket’ of its own bristles.

Steffen Bayer at the State Museum of Natural History Karlsruhe in Germany and his colleagues detail the anatomy of one new spider species, Evippomma rechenbergi, from specimens found in Morocco. The creature boasts exceptionally long silk-extrusion nozzles, which allow it to dab silk between individual sand grains and stabilize the walls of its tube-shaped hideaway.

Rainer Foelix at the New Cantonal School Aarau in Switzerland and his colleagues describe the sand-carrying habits of E. rechenbergi and a species of giant crab spider, Cebrennus rechenbergi, living in dunes of the same region. C. rechenbergi digs its tubular burrow by carrying out a load of sand in a ‘basket’ of bristles protruding from its face and front appendages. A similar basket evolved independently in desert ants, the authors note.

Meet the Moroccan Flic-Flac Spider (Cebrennus rechenbergi) a truly unique spider that moves using flic-flac jumps! C. rechenbergi is a huntsman spider indigenous to Morocco, found in the sand dunes of the Erg Chebbi desert. When provoked or threatened, the flic-flac spider can escape by doubling its normal walking speed using forward or backward flips similar to acrobatic flic-flac movements used by gymnasts. C. Today, it is the only spider known to use this unique form of rolling locomotion.

The discovery of species has influenced biomimetic robot research, resulting in the development of an experimental robot based on the spider's motion.

Not sure about those spiders but I have seen camel spiders out in Afghanistan. Those critters get pretty big and can put up a good fight with other critters such as scorpions and win.

Hey they've been evolving for millions of years. These things know how to do anything they NEED to. Very impressive. We're only here right now chatting online because we started eating bone marrow and growing our brains.
