...Yu Zeng; Grisanu Naing; Vivian Lu; Yuexiang Chen; Robert Dudley ABSTRACT Many wingless arboreal arthropods can glide back to tree trunks following free falls. However, little is known about the behaviors and aerodynamics underlying such aerial performance, and how this may be influenced by body...

... may limit body size, especially if the integument also functions in support or locomotion. Pycnogonids, or sea spiders, are marine arthropods that lack gills and rely on cutaneous respiration but still grow to large sizes. Their cuticle contains pores, which may play a role in gas exchange. Here, we...

Finally, we present the first evidence for the presence of melanosomes in arthropods, using both scanning and transmission electron microscopy, overturning the assumption that melanosomes are a synapomorphy of vertebrates. Our research shows...

...Verner P. Bingman; Jacob M. Graving; Eileen A. Hebets; Daniel D. Wiegmann ABSTRACT Amblypygids, or whip spiders, are nocturnal, predatory arthropods that display a robust ability to navigate to their home refuge. Prior field observations and displacement studies in amblypygids demonstrated...

To gain insights into the ancestral function and evolution of the visual system in panarthropods, we investigated phototactic behaviour, opsin gene expression and the spectral sensitivity of the eyes in two...

...Tom Weihmann; Michael Günther; Reinhard Blickhan SUMMARY Unlike most other arthropods, spiders have no extensor muscles in major leg joints. Therefore, hydraulic pressure generated in the prosoma provides leg extension. For decades, this mechanism was held responsible for the generation...

... and the strain patterns for 177c and 179 were determined (see Delp et al., 1990 ; Full and Ahn, 1995 ). Muscle strain is directly proportional to joint angle in insect legs because these muscles insert on apodemes (arthropod ‘tendon’), which are 40 times stiffer than vertebrate tendon ( Ker, 1977 ). Given...
