Sažetak
This paper presents a long-term experiment aiming to assess the feeding habits of a predatory marine gastropod species, Hexaplex trunculus (Linneaeus, 1758), under a range of pH conditions relevant in the context of ocean acidification (8.1 to 7.4). There was no significant relationship between the feeding rate (mussel week-1) and pH after a 40- week exposure (F1, 8=2.31, R2=0.25, p=0.25). After 60 weeks of exposure, no difference was observed between pH treatments in number of snails successfully reaching their food (success 66.7%), but the time to reach the food significantly differed (F2, 21=3.98, p=0.034) and showed a positive trend toward shorter duration (min) at lower pH. The data suggest that ocean acidification will not negatively impact feeding habits of this species.
