Cover: Fan worms (Annelida: Sabellidae) can rapidly withdraw their tentacles, which are covered in heavily ciliated ramifications called pinnules, into their tubes to protect them from approaching threats. Jiang et al. (jeb245731 ) show that, in order to achieve these rapid, forceful movements through seawater without damaging their tentacles, fan worms have developed functional morphological adaptations to reduce fluidic drag, including the flattening of their radiolar pinnules and the deformation of bodily segmental ridges.

REVIEWS
Adaptive echolocation behavior of bats and toothed whales in dynamic soundscapes
Summary: This Review compares echolocation in bats and toothed whales, with special emphasis on predator–prey interactions and adaptive sonar behaviors used to negotiate complex natural scenes.
Effects of wing damage and moult gaps on vertebrate flight performance
Summary: The flight apparatus (wings, flight muscles, neuro-muscular control) of vertebrates is fine-tuned for efficient flight. I review causes and consequences of wear, damage and moult gaps that temporarily affect wing morphology and flight performance.
SHORT COMMUNICATION
Close encounters of three kinds: impacts of leg, wing and body collisions on flight performance in carpenter bees
Summary: Flying insects frequently collide with obstacles when navigating dense clutter, but the performance consequences of collisions depend on which parts of the insect (e.g. leg, wing, body) are involved.
RESEARCH ARTICLES
Hawkmoths regulate flight torques with their abdomen for yaw control
Summary: Quantitative analysis of flight behavior, modeling and numerical simulation shows that the abdomen of hawkmoths can regulate wing-generated flight torques about the vertical (yaw) axis.
Developmental environment has lasting effects on amphibian post-metamorphic behavior and thermal physiology
Climatic stressors during development have lasting impacts on the thermal physiology, performance and behavior of juvenile frogs post-metamorphosis, with implications for susceptibility to predators and pathogens in subsequent life stages.
Regulation of the swimming kinematics of lampreys Petromyzon marinus across changes in viscosity
Summary: Swimming lampreys largely compensate for changes in viscosity, maintaining similar kinematics over 20× changes in viscosity, suggesting that they use sensory feedback to regulate their body waveform.
Low production of mitochondrial reactive oxygen species after anoxia and reoxygenation in turtle hearts
Low rates of mitochondrial O2·− production are responsible for lack of tissue damage upon reoxygenation after anoxia in turtles, likely owing to low succinate accumulation and low degradation of adenine nucleotides.
Rapid manoeuvre of fan worms (Annelida: Sabellidae) through tubes
To achieve rapid movements through seawater, fan worms have developed functional morphological adaptations to reduce fluidic drag, including the flattening of their pinnules and the deformation of bodily segmental ridges.
Sensorimotor control of swimming Polypterus senegalus is preserved during sensory deprivation conditions across altered environments
Summary: Lateral line and visual systems of Polypterus senegalus are not critical for responding to fluid viscosity but may be involved in a forward model of motor control to adjust locomotion.
Experimental reduction in blood oxygen-carrying capacity alters foraging behaviour in a colonial waterbird
Summary: Experimental reduction of blood oxygen-carrying capacity in incubating black-headed gulls results in fine-scale alterations in foraging behaviour, as birds with induced haemolytic anaemia perform fewer, but longer foraging trips.
ECR SPOTLIGHTS
2023 JEB Outstanding Paper Prize shortlist and winner
The JEB Editors are delighted to announce the shortlisted authors for the 2023 JEB Outstanding Paper Prize. Read the winning paper - Tiny spies: mosquito antennae are sensitive sensors for eavesdropping on frog calls - by Hoover Pantoja-Sanchez and Brian Leavell from Ximena Bernal's lab at Purdue University, USA.
JEB Science Communication Workshop for ECRs
If you’re an early-career researcher interested in science communication and are attending the SEB Annual Conference in Prague this summer, come a day early and join the JEB Editors at a sci comm workshop to learn the key writing skills needed to promote your research to a broad audience beyond your peers (1 July at 14.30-17.30). Places are limited to 24 attendees, and applicants should apply through the SEB registration page by 30 April 2024.
Bridging the gap between controlled conditions and natural habitats in understanding behaviour
Novel technologies enable behavioural experiments with non-model species, in naturalistic habitats and with underexplored behaviours. In their Commentary, Scholz and colleagues discuss how to obtain a deeper understanding of the natural ecology and lifestyle of study animals.
Beluga metabolic measures could help save species
To help save animals from extinction, it’s important to understand what each species needs to survive. This led Jason John et al. to measure the metabolic rates of captive belugas to develop a ‘fish calculator’ showing that the whales need to eat ~23 salmon per day.
ECR Workshop on Positive Peer Review
Are you an ECR looking for tips on how to write concise, astute and useful manuscript reviews? If so, join the JEB Editors at a 2-hour JEB-sponsored Workshop on Positive Peer Review at the Canadian Society of Zoologists annual meeting in Moncton on 9 May 2024 at 13.00-15.00. There are 25 spaces for ECRs and selection is first come, first serve. To sign up, check the ECR Workshop box when you register for the CSZ meeting.
