The main reason fishermen kill sharks and take their fins is to supply the demand for shark fin soup, which many people mistakenly believe gives them sexual potency.

Shark meat contains dangerously high levels of mercury and other heavy metals.

Sharks really don’t like to eat humans because we’re too bony. They’d much rather have a fat seal for dinner.
