According to several scientific studies, certain parasites, such as fish intestinal worms, have been shown to accumulate heavy metals at concentrations significantly higher than in their hosts' tissues. While the term "eat" is anthropomorphic, parasites can absorb and concentrate heavy metals from their host's environment.

According to scientific studies, snails living in mercury-polluted environments are known to accumulate the toxic heavy metal in their tissues. The presence of mercury in snails is not uniform and largely depends on their habitat and surrounding contamination levels.
