Cover: In Amphimedon queenslandica larvae, phototaxis is conferred by posterior, concentric rings of pigmented and ciliated cells. This image is artificially colored to highlight ciliated cells (purple) that act as light-responsive 'rudders' to steer the living larvae. Because sponges are not known to possess nervous systems or opsins, the molecular components of sponge phototaxis must differ from other animals. Rivera et al. (pp. 1278−1286) characterize two cryptochrome genes in A. queenslandica. One is expressed near the pigment ring, and its protein contains a co-factor responsive to wavelengths of light that also mediate photic behavior, suggesting a cryptochome may act in the aneural, opsin-less eye of a sponge.

The Integrative Biology of the Heart
We are pleased to welcome submissions to be considered for our upcoming special issue: The Integrative Biology of the Heart, guest edited by William Joyce and Holly Shiels. This issue will consider the biology of the heart at all levels of organisation, across animal groups and scientific fields.
JEB@100: an interview with Monitoring Editor John Terblanche
John Terblanche reveals how he narrowly avoided becoming a sports scientist and why he thinks phenotypic plasticity is the big question currently facing comparative physiologists. Find out more about the series on our Interviews page.
Vision 2024: Building Bridges in Visual Ecology
Early-career researchers can apply for funded places at our Vision 2024: Building Bridges in Visual Ecology. The event is organised by Eleanor Caves, Sonke Johnsen and Lorain Schweikert and being held at Buxted park 10-13 June 2023. Deadline 1 December 2023.
Reconciling the variability in the biological response of marine invertebrates to climate change
Drawing on work in reef-building corals, Zoe Dellaert and Hollie Putnam provide historical context to some of the long-standing challenges in global change biology that constrain our capacity for eco-evolutionary forecasting, as well as considering unresolved questions and future research approaches. Read the full Centenary Review Article here.
Sipping takes no effort for hovering hawkmoths
Hovering takes the most effort so how much energy does sipping require when hawkmoths hover? Next to nothing, apparently. Alexandre Palaoro & colleagues have discovered that the insects’ proboscises are incredibly wettable, drawing nectar along the length with no effort, giving them a free drink on the wing.
