<p>Climate change is the leading cause in the acidification of marine ecosystems, which may influence the chemo-detection of prey by the sea star Pycnopodia helianthoides. Interference with predation may negatively impact marine food-web dynamics in P.</p>
<p>helianthoides habitats. We explored how the detection of the blue mussel Mytilus edulis varied in 15 P. helianthoides specimens in lowered pH seawater and 15 specimens in current pH seawater. We observed that there was no significant difference in the number of prey detected by P. helianthoides between the treatments and that no significant difference was present between the durations of successful trials. These results indicate that future marine acidification may not have as large of an impact on Pycnopodia helianthoides foraging as expected.</p
