Short summary

This paper combines a literature review with a 1D Hg speciation and bioaccumulation model to assess how feeding strategy affects inorganic and methylmercury at the base of marine food webs. We find filter feeders have higher MeHg, while suspension feeders have very low MeHg, highlighting feeding strategy as a key driver of MeHg variability.
