Cover: This juvenile Apteronotus leptorhynchus, or brown ghost knifefish, belongs to one of approximately 200 species of South American gymnotiform weakly electric fishes. These animals use an active electrosense for foraging at night in often turbid waters as well as for communication. The total energetic cost of their electric behaviour, including generation and sensing of the electric field, is estimated to be about 30% of routine metabolic rate (Salazar et al., pp. 2459−2468). The articles in this special issue review the remarkable recent contributions of research on electric fishes to energetics and many other areas of biology.

Sensory perception in a changing world – join us in Liverpool in March 2025
We are excited to invite you to a unique scientific conference, celebrating the 100-year anniversary of The Company of Biologists, and bringing together our different communities. The conference will incorporate the JEB Symposium Sensory Perception in a Changing World and the SEB satellite meeting. Find out more and register to join us in March 2025 in Liverpool, UK. Submit your abstract by 17 January 2025. Early-bird registration ends on 17 January 2025.
Extraordinary creatures: mantis shrimp
In our new Conversation series focusing on extraordinary creatures, Tom Cronin and Sheila Patek tell us about the incredible biology of mantis shrimp, from their complex vision to their powerful striking abilities.
Behaviour as a physiological process
In this Commentary, Shamil Debaere & colleagues argue the case for integration of behaviour into animal physiology, and advocate for behaviour to be considered as a physiological process.
Tiny ring-necked snakes keep warm heads despite their size
Some ectotherms are able to raise the temperature of certain body parts above the temperature of other regions & now Christian Fox and Albert Chung, with undergraduates from the University of Virginia, reveal that the heads of tiny ring-necked snakes can be 2.1C warmer than their tails, even though they are only 20cm long.
