Issues

Cover: Northern clingfish (Gobiesox maeandricus) in the marine intertidal of San Juan Island, WA, USA. Tides, continually pounding waves and stones of varying surface roughness make the intertidal a challenging environment. Clingfish have a suction cup on their belly with which they can attach to stones. Ditsche et al. (pp. 2548−2554) show that clingfish can hold on to extremely rough surfaces, even those that are covered with slippery microorganisms and algae. On these fouled surfaces, this small benthic fish can hang on tightly enough to launch attacks on the archetypal attached mollusk, the limpet. Photo credit: P. Ditsche.
