Journal of Experimental Biology is the leading journal in comparative animal physiology and biomechanics. We cover a broad range of integrative, comparative, ecological and evolutionary physiology and biomechanics research in animals at all levels of biological organisation, from the molecular to the integrated whole animal. 

Our authors and readers reflect a broad interdisciplinary group of scientists who study comparative biomechanics and molecular, cellular and organismal physiology in an evolutionary and environmental context.

About JEB

SPECIAL ISSUE – Developmental Plasticity: From Mechanisms to Evolutionary Processes

Special issue - A Century of Comparative Biomechanics

This special issue aims to enlighten readers on many aspects of ‘developmental plasticity’ – i.e. how environmental conditions experienced during early life can shape how an animal grows and matures into an adult, with long-lasting impacts on form and function. The series of Review articles covers a rich diversity of taxa - from worms to dung beetles and lizards to mice - and raises pressing questions for further research in the areas of physiology and evolution.

Open Access publishing options

We recognise the benefits of Open Access publishing and, as one of the very first Transformative Journals, we offer several publishing options to all of our authors, whatever their funder or financial status.

The Forest of Biologists The Forest of Biologists leaves icon

As part of a biodiversity initiative from The Company of Biologists, JEB plants a native tree in a UK forest for each published Research and Review article. We are also funding the restoration and preservation of ancient woodland and dedicating these trees to our peer reviewers. All of these trees are represented together in a virtual forest. Find out more about The Forest of Biologists.


Extraordinary creatures: notothenioids and icefish

Christina Cheng and Kristin O'Brien tell us about the remarkable freeze tolerant nototheniods that live in the Southern Ocean and how icefish are the only adult vertebrates that survive without haemoglobin.

JEB celebrated 100 years of discovery in 2023 - hear the Editors' thoughts about the journal and the future of their fields.

In the field

Featured articles

Editors' choice

When most birds moult they are at risk of getting chilly, but not gentoo penguins. Agnès Lewden and colleagues show that, during their moult, they grow a double layer, keeping the original feathers before shedding the old, potentially causing them to overheat when its hot.
