..., the influence of multimodal cues on receiver learning and/or memory has not been studied in invertebrates. Here, we test the hypothesis that the presence of a seismic (vibratory)stimulus improves color discrimination learning in the jumping spider Habronattus dossenus . Using a heat-aversion learning experiment...

...Damian O. Elias; Andrew C. Mason; Wayne P. Maddison; Ronald R. Hoy SUMMARY Visual displays in jumping spiders have long been known to be among the most elaborate animal communication behaviours. We now show that one species, Habronattus dossenus , also exhibits an unprecedented complexity...

...Duane P. Harland; Robert R. Jackson SUMMARY Portia fimbriata from Queensland, Australia, is a jumping spider(Salticidae) that preys on other spiders, including other salticids. Cryptic stalking (palps retracted, walking very slowly and freezing when faced) is a prey-specific tactic deployed...

...Anke Schmitz; Steven F. Perry SUMMARY In jumping spiders, both the book lungs and the tracheal system are well-developed. The tracheal system consists of four thick primary tracheae that branch into small secondary tracheae, some of them ending in the opisthosoma and others entering the prosoma. We...

...Duane P. Harland; Robert R. Jackson ABSTRACT Portia fimbriata from Queensland, Australia, is an araneophagic jumping spider (Salticidae) that includes in its predatory strategy a tactic (cryptic stalking) enabling it to prey effectively on a wide range of salticids from other genera. Optical cues...

...M. F. Land ABSTRACT Most spiders have eight simple eyes, of which one forward-pointing pair (the principal eyes) has a different structure from the other three pairs (the secondary eyes). The principal eyes are often movable, whereas the secondary eyes are fixed. In most jumping spiders (Salticidae...
