Cover: An unfed and fully engorged female of the South African bont tick, Amblyomma hebraeum Koch 1844 (Arachnida: Acari: Ixodidae); the family is colloquially known as 'hard ticks'. Full engorgement requires 7−10 days of feeding; the total increase in body mass can exceed 100-fold. In this issue W. R. Kaufman, P. C. Flynn and S. E. Reynolds (pp. 2820-2831) describe some changes in the mechanical properties of the alloscutal cuticle that are believed to facilitate expansion of the tick during feeding.

Manipulation of mitochondrial function affects red carotenoid metabolism in a marine copepod
Tigriopus californicus copepods with the most powerful mitochondria are the brightest red, providing an honest and direct link between the attractiveness of a creature and their metabolic prowess.
The physiological cost of colour change
In their Review, Ateah Alfakih, Penelope Watt and Nicola Nadeau discuss the energetic cost of colour change and highlight how this can be avoided or lessened in animals that change colour rapidly or slowly.
