After nearly a decade and a half, there is finally good news for the dusky shark. Off KwaZulu-Natal, the use of shark nets to protect beaches has reduced the populations of these larger predators, leading to a studied increase in the number of juvenile Dusky sharks (a phenomenon called predator release). The dusky shark is one of the largest U.S. Atlantic shark species, and it is also one of the most imperiled. This method can also be used to prepare shark fin soup, which is a popular dish in many Asian countries.

In one interesting South African study, recorded data confirmed that 0.2% of the sharks examined had preyed on Bottlenose dolphins. After wolves starting to return to healthy population levels in Yellowstone, scientists discovered just how intricately involved wolves are in maintaining healthy populations of prey species and how profoundly that trophic cascade affects the rivers and plantsthe very habitatthat sustains the ecosystem. [15] This interpretation was largely upheld by Leonard Compagno in his 1988 phenetic study,[16] and by Gavin Naylor in his 1992 allozyme sequence study. They are also known for their seasonal migrations, for which they form temporary schools, disbanding and becoming solitary once they reach their destination.
