Long Lifespan and Size (Bioaccumulation)</h3>Sharks are long-lived predators. Over time, they accumulate mercury—mostly in the form of methylmercury, a highly toxic organic form—in their tissues by eating contaminated fish and marine organisms. This is called bioaccumulation.<hr /><h3><img class="smilie smilie--emoji" loading="lazy" alt="🐟" title="Fish    :fish:" src="https://cdn.jsdelivr.net/joypixels/assets/6.6/png/unicode/64/1f41f.png" data-shortname=":fish:" /> 2. Top of the Food Chain (Biomagnification)</h3>Mercury levels increase up the food chain. Smaller fish ingest mercury from plankton and sediment, larger fish eat those fish, and sharks eat those larger fish. This process is called biomagnification, and it results in very high mercury concentrations in apex predators like sharks.<hr /><h3><img class="smilie smilie--emoji" loading="lazy" alt="🌊" title="Water wave    :ocean:" src="https://cdn.jsdelivr.net/joypixels/assets/6.6/png/unicode/64/1f30a.png" data-shortname=":ocean:" /> 3.

Fish absorb it through gills and diet, and it moves up the food chain.<hr /><h3><img class="smilie smilie--emoji" loading="lazy" alt="🍼" title="Baby bottle    :baby_bottle:" src="https://cdn.jsdelivr.net/joypixels/assets/6.6/png/unicode/64/1f37c.png" data-shortname=":baby_bottle:" /> Why It’s a Health Concern</h3>Because of the high mercury levels, health organizations advise against frequent consumption of shark meat—especially for pregnant women and young children, as mercury can damage the developing nervous system.</blockquote>
