Moroccan Flic-flac Spider
''Cebrennus rechenbergi'', also known as the Moroccan flic-flac spider and cartwheeling spider, is a species of huntsman spider indigenous to the sand dunes of the Erg Chebbi desert in Morocco. If provoked or threatened it can escape by doubling its normal walking speed using forward or backward flips similar to acrobatic flic-flac movements used by gymnasts. ''C. rechenbergi'' is the only spider known to use this unique form of rolling locomotion. The discovery of the Moroccan flic-flac spider has influenced biomimetic robot research, resulting in the development of an experimental robot based on the spider's motion.King, R.S. (2013).

Etymology The spider is named after its discoverer, Ingo Rechenberg, bionics professor at the Technische Universität Berlin. Rechenberg may have first encountered the spider on a trip to Morocco ...

Peter Jäger
Peter Jäger is a German people, German arachnologist, and current Head of Arachnology at the Naturmuseum Senckenberg, Senckenberg Research Institute and Natural History Museum in Frankfurt, Germany. He has named several spiders after celebrities; in 2008, he named ''Heteropoda davidbowie'' after British singer David Bowie, and ''Heteropoda ninahagen'' after German singer Nina Hagen. In 2013, he named ''Bowie monaghani, Ctenus monaghani'' (currently in the genus ''Bowie (spider), Bowie'') after actor Dominic Monaghan, to honor his work in the documentary series ''Wild Things with Dominic Monaghan''. In 2020, Jäger named a new genus and species of huntsman spiders from Madagascar after Greta Thunberg. The new spider is named ''Thunberga greta''. In 2022, he named 54 species of huntsman spiders from across Asia under the new genus ''Bowie (spider), Bowie'' in commemoration of the musician David Bowie 75th's birthday, the second time the musician's name was honored.

Opisthosoma
The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax). It is a distinctive feature of the subphylum Chelicerata (arachnids, horseshoe crabs and others). Although it is similar in most respects to an abdomen (and is often referred to as such), the opisthosoma is differentiated by its inclusion of the respiratory organs (book lungs or book gills) and the heart. Segments The number of segments and appendages on the opisthosoma vary. Scorpions have 13, but the first is only seen during its embryological development. Other arachnids have fewer; harvestmen, for instance, have only ten. In general, appendages are absent or reduced, although in horseshoe crabs they persist as large plate-like limbs, called opercula or branchiophores, bearing the book gills, and that function in locomotion and gas exchange. In most chelicerates the opisthosomal limbs are greatly reduced and persist only as specialized structures, such as the silk-producing ...

Spiders Described In 2014
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Sparassidae
Huntsman spiders, members of the family Sparassidae (formerly Heteropodidae), are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places (forests, mine shafts, woodpiles, wooden shacks). In southern Africa the genus ''Palystes'' are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related. More than a thousand Sparassidae species occur in most warm temperate to tropical regions of the world, including much of Australasia, Africa, Asia, the Mediterranean Basin, and the Americas. Several species of huntsman spider can use an unusual form of locomotion. The wheel spider (''Carparachne aureoflava'') from the Namib uses a cartwheeling motion which gives it its name, while ''Cebrennus rechenbergi ...
