Originally published by Harper Collins in a US edition in June of 2019, the cover of William McKeever’s “Emperors of the Deep; Sharks; The Ocean’s Most Mysterious, Most Misunderstood, and Most Important Guardians” depicts a sharply defined photographic image of a shark as it swims boldly yet smoothly through its aquatic realm. However, the visual, as well as psychological, effect of the first UK edition, published by Harper Collins UK in July of 2020 under the somewhat modified title of “Emperors of the Deep; The Ocean’s Most Mysterious, Misunderstood and Important Guardians” is a world away from its American predecessor – and these differences are indeed significant in the first impressions the respective covers make.
