<DIV class=Abstract>Since the collapse of the pelagic fisheries off southwest
Africa<SUP> </SUP>in the late 1960s, jellyfish biomass has increased and the
structure<SUP> </SUP>of the Benguelan fish community has shifted, making the
bearded<SUP> </SUP>goby (<I>Sufflogobius bibarbatus</I>) the new predominant
prey species.<SUP> </SUP>Despite increased predation pressure and a harsh
environment,<SUP> </SUP>the gobies are thriving. Here we show that physiological
adaptations<SUP> </SUP>and antipredator and foraging behaviors underpin the
success<SUP> </SUP>of these fish. In particular, body-tissue isotope
signatures<SUP> </SUP>reveal that gobies consume jellyfish and sulphidic
diatomaceous<SUP> </SUP>mud, transferring "dead-end" resources back into the
food chain.<SUP> </SUP>
