Figures
- Fig. 1.
Prey choices of test spiders. (A) Percentage of test spiders that responded during prey-choice tests at each light level. (B) Prey choices made by test spiders that responded. N values are shown within each bar in A and B; data for B are based on the black area in A. Ca: Cyrba algerina. Co: Cyrba ocellata.
- Fig. 2.
Percentage of test spiders that responded during mirror rival-identification tests at each light level. A response was recorded when a spider adopted a threat display while its gaze was fixated on the mirror. Ca: Cyrba algerina. Co: Cyrba ocellata. N is shown within each bar.
- Fig. 3.
Pre-prey-choice fixation of gaze on lures by spiders at different light levels. Data for C. algerina (white) and C. ocellata (gray) are medians, with 25th and 75th percentiles; whiskers indicate minimum and maximum. (A) Distance at which test spiders fixated their gaze on the lures and then, without breaking fixation, chose a lure. (B) Time elapsed between fixating their gaze on the lures and, without breaking fixation, choosing a lure. N is shown in A.
- Fig. 4.
Responses of spiders to a mirror image at different light levels. Data are means±s.e.m. for C. algerina (circles) and C. ocellata (squares). (A) Virtual distance from the mirror image at which spiders first displayed. (B) Time elapsed between the test spider fixating its gaze on its mirror image and then, without breaking fixation, initiating display. (C) Virtual distance (2× distance) at which the test spider first fixated its gaze on its mirror image and then, without breaking fixation, performed a threat display. N is shown above the x-axis in A.

Editorial – The changing of the guard
In his Editorial, Hans Hoppeler announces that he will be stepping down as Editor-in-Chief of JEB in July 2020. He reflects on the history of JEB, why he has enjoyed his tenure as JEB’s Editor-in-Chief and the recent developments in the publishing world.
Big Biology podcast
JEB is partnering with the Big Biology podcast and in this sponsored episode, JEB Editor Michael Dickinson talks to the Big Biology team about the aerodynamic mechanisms of insect flight, how insects control flight with their tiny 100k neuron brain and his recent JEB paper showing how fruit flies navigate using the sun and polarized light as a compass.
Editors’ choice – An appetite for invasion: digestive physiology, thermal performance and food intake in lionfish (Pterois spp.)
Invasive lionfish are a colossal problem in the Mediterranean Sea and western Atlantic Ocean. Now it turns out that they are successful invaders because they invest more energy in digestion than moving about.
Travelling Fellowship – Anti-ageing in the Greenland Shark
Find out how Pierre Delaroche’s Travelling Fellowship grant from the Journal of Experimental Biology took him to Greenland, where he gathered data to further understand the ageing process in the longest-living vertebrate known to science. Don’t miss the next application deadline for 2020 travel, coming up on 29 November. Where will your research take you?
Commentary – Yank: the time derivative of force is an important biomechanical variable in sensorimotor systems
The derivative of force with respect to time does not have a standard term in physics. In their new Commentary, David C. Lin and his colleagues propose that the term ‘yank’ should be used to denote the time derivative of force.
Runners waste energy every time their legs stop swinging, but now a team of scientists from the US and Canada have shown that a springy ankle tether can reduce runners’ energy costs by 6.4%, which is nearly the entire cost of swinging the limbs. Read the full research article here.
Journal of Experimental Biology is pleased to announce a new partnership with Publons! This allows reviewers to easily track and verify every review by choosing to add the review to their Publons profile when completing the review submission form. Publons also makes it simple for reviewers to showcase their peer review contributions in a format that can be included in job and funding applications (without breaking reviewer anonymity).

preLights – Oxygenation properties of hemoglobin and the evolutionary origins of isoform multiplicity in an amphibious air-breathing fish, the blue-spotted mudskipper (Boleophthalmus pectinirostris)
Charlotte Nelson highlights work in mudskippers suggesting that a diversity in expressed hemoglobin isoforms is not required for the switch between aquatic and aerial respiration.
