Testing sharks that have attacked cocaine stashes? I wonder who's volunteering to be on that crew?

Animals have been testing positive for pharma since we started flushing toilets. I would agree it's somewhat unusual for marine animals not restricted in place the way shellfish are.

When I worked in marine biology, which was 4 decades ago and in an extremely junior bottle-washer role, shellfish were the useful indicator of pollution in marine systems because as filter feeders they concentrate things pretty much to survive, from the passing water flows. They can be motile, but they don't shake their booty off thousands of kilometres, except in the larval state or as passing seaweed and flotsam and jetsam.

Shark bites thing floating in water? Seems normal to me.

How do whales get the horrendously high PCB rates into their blubber?
