Cover legend: Composite image of a salamander (Eurycea guttolineata) capturing a cricket with high-speed tongue projection. The cricket's velocity is such that, were the salamander to project at the delayed neural image formed on the retina, it would miss the cricket by a full body length. Salamanders aim their tongues by using linear extrapolation to estimate future prey position, thereby compensating for internal delays from both visual and motor processing. For more information, see the article by Borghuis and Leonardo (pages 15430–15441).
