Pandiculation documented in a spider

نویسندگان

چکیده

After a long period of waiting in ambush on the hub its orb web, an araneid spider (Cyclosa argenteoalba) was found to stretch out body and legs, exhibiting distinctive behavior known as pandiculation (https://bit.ly/2TUp5SY). This coordinated movement is clearly different from that excretion (https://bit.ly/3fzwcYR). Pandiculation natural instinctive activity, often accompanying yawning, performed broadly by mammals (including humans) birds (Appl Anim Behav Sci 1989; doi.org/10.1016/0168-1591(89)90117-2), while only yawning reptiles, amphibians, fish, excluding sharks rays (Psychon B Rev 1997; doi.org/10.3758/BF03209394). However, along with other arthropods, spiders belong Protostomia, which phylogenetically very distant Deuterostomia, whose members include vertebrates. Whether has evolved once or separately Mammalia/Aves Araneae still uncertain, but discovery suggests this may be exhibited arachnids perhaps arthropods even Protostomia well. Within Arthropoda, possibility via spiracles (exoskeletal openings associated respiration) should also considered.

Documented bites by a yellow sac spider (Cheiracanthium punctorium) in Italy: a case report

Since increasing clinical information would improve understanding of the danger of yellow sac spiders to humans, we report the case of a 7-year-old child and her father bitten by a documented Cheiracanthium punctorium. They developed acute persistent pain with local skin signs and numbness, and required emergency ...

Documented Data Dispersal

We define the Documented Data Dispersal (DDD) problem as determining, given inputs, outputs, and an application connecting them, whether or not a certain input was used to produce a certain output. There exist many possible ways to address this problem. All of the solutions can be characterized by the level of program analysis, instrumentation, and data analysis that they perform. These paramet...

Alamo Impact Crater Documented

Introduction: The early Late Devonian, wet-target Alamo Event at southern Nevada resulted in one of the best-exposed and well-dated impact deposits ever documented, the Alamo Breccia [1]. Because post-impact geologic processes have modified, obscured [2, 3] and perhaps wiped away its original morphological and architectural relationships, the crater stratigraphy has remained uncertain. Thus, th...
