The Shark (Used to Have) Pearly Teeth

Sharks are apex (top) predators. Although many humans regard sharks as being marine hazards, they are actually crucial for the ecological balance of the Earth's oceans. We already know that sharks are overfished for shark's fin soup ingredients. Ben Wainwright and Ian French (Yale-NUS College. Singapore) have now found genetic evidence of endangered (and protected) sharks in several brands of dog and cat food (https://www.theguardian.com/environment/2022/mar/04/endangered-sharks-found-in-cat-and-dog-food-dna-study-shows). Wainwright and French, note that some of the brands only list 'ocean fish' in their ingredients list. Many pet owners, they suspect, would be unwilling to feed their cat or dog from a can emblazoned with the promise 'Made from the Finest Endangered Sharks'. This seems to be another example of employing vagueness to promote sales.
