A newly metamorphosed two-day-old juvenile of the Australian sea-urchin Heliocidaris erythrogramma. In freespawning species such as this, the order in which males mate affects the quality of the offspring that they sire. See Marshall et al. Proc. R. Soc. B. 271, 1585–1589 (photograph, R. Emlet). Top: A male Bar-tailed Godwit (Limosa lapponica taymyrensis) refuelling on the Wadden Sea stopover site after a 4500 km non-stop migratory flight from west African wintering grounds (see pages 295–302; photograph, Jan van de Kam). Middle: a complete fossil gull, including the eye ball and rings, from the Danish Palaeocene (about 60 million years old, see pages 289–294; photograph, Sten Jakobsen, Geologisk Museum, Copenhagen). Bottom: a foraging queen of the bumblebee, Bombus terrestris, as frequently seen in early spring before colony foundation (see pages 319–323; photograph, Boris Baer).
