  abstract = {{E}nvironmentally-induced changes in fitness are mediated by direct effects on physiology and behaviour, which are tightly linked. {W}e investigated how predicted ocean warming ({OW}) and acidification ({OA}) affect key ecological behaviours (locomotion speed and foraging success) and metabolic rate of a keystone marine mollusc, the sea hare {S}tylocheilus striatus, a specialist grazer of the toxic cyanobacterium {L}yngbya majuscula. {W}e acclimated sea hares to {OW} and/or {OA} across three developmental stages (metamorphic, juvenile, and adult) or as adults only, and compare these to sea hares maintained under current-day conditions. {G}enerally, locomotion speed and time to locate food were reduced ~1.5- to 2-fold when the stressors ({OW} or {OA}) were experienced in isolation, but reduced ~3-fold when combined. {D}ecision-making was also severely altered, with correct foraging choice nearly 40% lower under combined stressors. {M}etabolic rate appeared to acclimate to the stressors in isolation, but was significantly elevated under combined stressors. {O}verall, sea hares that developed under {OW} and/or {OA} exhibited a less severe impact, indicating beneficial phenotypic plasticity. {R}educed foraging success coupled with increased metabolic demands may impact fitness in this species and highlight potentially large ecological consequences under unabated {OW} and {OA}, namely in regulating toxic cyanobacteria blooms on coral reefs.},
