In recent articles Vogt (1975, 1977, 1980) and Land (1976, 1978) have put forward a theory of reflection optics as a method by which a superposition image is formed on the retina in macruran decapods, notably the crayfish. A feature of the reflecting superposition eyes investigated so far by Vogt & Land is that the corneal facets have negligible focusing properties, such focusing as exists being achieved by total internal reflection in the proximal part of the crystalline cone. The present work shows for the first time that the cornea of an Australian crayfish, Cherax destructor, which otherwise has all the required anatomical features of such a reflecting superposition eye (Fig. 1 A, B, C), possesses corneal facet lenses each of which focuses light from a distant object (forming a real inverted image) to a position behind the cornea approximately corresponding to...
Using the reactive scope model to redefine social stress in fishes
In their Review, Katie Gilmour and colleagues redefine the ambiguous concept of social stress by using the reactive scope model as a framework to explain the divergent physiological phenotypes of dominant and subordinate fishes.

Thirteen-lined ground squirrels survive extraordinarily low blood oxygen
Brynne Duffy and colleagues reveal that thirteen-lined ground squirrels are true hypoxia champions surviving extreme low blood oxygen, down to just 34% oxygen, when they emerge briefly from hibernation.
The Company of Biologists Workshops
For the last 15 years, our publisher, The Company of Biologists, has provided an apt environment to inspire biology and support biologists through our Workshops series. Read about the evolution of the Workshop series and revisit JEB's experience with hosting the first Global South Workshop.
Fast & Fair peer review
Our sister journal Biology Open has recently launched the next phase of their Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. To learn more about BiO’s progress and future plans, read the Editorial by Daniel Gorelick, or visit the Fast & Fair peer review page.
