Marine gastropods at higher trophic levels are more tolerant to ocean acidification. A study using snails showed that predators and acidity affect their body and shell characteristics. Predators have a bigger impact on lower trophic level snails, while acidity affects higher trophic level snails more. This suggests that higher trophic level species can better maintain their traits in the face of climate change, while lower trophic levels rely more on defense mechanisms against predators.
