Methylmercury tends to accumulate most in which type of fish species?
Answer
Larger, predatory species
The accumulation of methylmercury in aquatic life is closely linked to the fish's position in the food chain and its lifespan. Specifically, larger predatory fish, which often live for longer periods, have more time to accumulate contaminants from the smaller organisms they consume. This bioaccumulation results in significantly higher levels of mercury in these top-of-the-food-chain species. Conversely, the recommended low-mercury options, such as salmon, cod, and sardines, are generally smaller fish that do not live as long and therefore accumulate far lower concentrations of this toxin.
