Lennart Verheuvel / Wildlife Photographer of the Year
Lennart Verheuvel shows the final moments of a beached orca.
Lying on its side in the surf, this orca had only a short time left to live. Initially rescued, it soon was stranded again on the beach and died. A study later revealed that not only was it severely malnourished, it was also extremely sick.
Research shows that orcas in European waters have the world’s highest concentrations of polychlorinated biphenyls. These banned chemicals can persist for many years in marine food webs, weakening immune systems and reducing breeding success in whales, porpoises and dolphins.
