Dusky sharks are not aggressive, but they will attack humans in self-defense (most attacks are provoked). Dusky sharks have a color of Gray or beige. [52], In addition to commercial shark fisheries, dusky sharks are also caught as bycatch on longlines meant for tuna and swordfish (and usually kept for its valuable fins), and by recreational fishers. Garrick, J.A.f. The Dusky Shark's habitat is on sandy beaches throughout the KwaZulu-Natal coast and in shallow bays along the south-eastern Cape coast, juveniles can be found in the surf zone. The study found that the Sandbar, Dusky, Great White, Whale, Dwarf Pygmy, and Hammerhead Sharks all had arsenic levels well beyond acceptable consumption standards. Stocks off the eastern United States are severely overfished; a 2006 stock assessment survey by the U.S. National Marine Fisheries Service (NMFS) showed that its population had dropped to 1520% of 1970s levels. Dusky sharks, also known as bronze or black whalers, are long-distance swimmers known for seasonal, temperature-driven migrations that males and females undertake in separate groups.
