Firefly flashing and jumping spider predation

Animal Behaviour, 2012
Bioluminescent flashing in fireflies, while primarily a sexual signal, is known to deter some predators while attracting others. We tested whether flashing serves an antipredator function against two species of diurnal, visually hunting jumping spiders, Phidippus princeps and Phidippus audax. To confirm anecdotal reports that fireflies flash during the

The jumping spiders of Mozambique (Araneae: Salticidae)

Zootaxa
Only 26 species of jumping spiders have been recorded from Mozambique to date. The present study is based on materials from four museum collections. Fourteen species are described as new to science: Habrocestum mozambicum sp. nov. (♂ ♀), Hyllus bisulcus sp. nov. (♂), H. ornatus sp. nov. (♂ ♀), H. simplex sp. nov. (♂), H. tetensis sp.

Place avoidance learning and memory in a jumping spider

Animal Cognition, 2016
Using a conditioned passive place avoidance paradigm, we investigated the relative importance of three experimental parameters on learning and memory in a salticid, Servaea incana. Spiders encountered an aversive electric shock stimulus paired with one side of a two-sided arena. Our three parameters were the ecological relevance of the visual stimulus,

Association and reversal learning abilities in a jumping spider

Behavioural Processes, 2014
The ability to learn and overwrite learned associations allows animals to respond adaptively to changes in their environment. However, such behavioural plasticity is presumed to be costly and the question arises to which extent animals with restricted neuronal capacity are capable of such flexible behaviour.

Rearing environment affects behaviour of jumping spiders

Animal Behaviour, 2000
We tested the effect of rearing conditions on the behaviour of jumping spiders, Phidippus audax. Spiders were assigned randomly to either small or large cages that either were empty or contained a painted dowel. Laboratory-reared spiders were raised from second instar to adult in these environments.

Dynamic Jump Motion Control of a Jumping Spider Robot with Redundant Degrees of Freedom

ACM Cloud and Autonomic Computing Conference, 2019
Aiming at the disadvantages of the traditional jumping robot, such as single jumping form and low movement efficiency, a hexapod robot based on jumping spider is constructed, which can realize multi-direction jumping.

Jumping kinematics in the wandering spider Cupiennius salei

Journal of Comparative Physiology A, 2010
Spiders use hemolymph pressure to extend their legs. This mechanism should be challenged when required to rapidly generate forces during jumping, particularly in large spiders. However, effective use of leg muscles could facilitate rapid jumping. To quantify the contributions of different legs and leg joints, we investigated jumping kinematics by high ...

Crystal structure of Jumping Spider Rhodopsin-1 bound to 9-cis retinal

, 2019
Light-sensitive G protein-coupled receptors (GPCRs)-rhodopsins-absorb photons to isomerize their covalently bound retinal, triggering conformational changes that result in downstream signaling cascades.
