India's River Shark Attacks

  • In India, the frightening scenario of a shark attack has a twist. The victims aren’t in the ocean . . . they’re waist-deep in a river. Wild Chronicles joins National Geographic researchers at the Bay of Bengal to find out why sharks are attacking in freshwater.

    1. Many Indians fish in the Bay of Bengal, a bull shark habitat. What are they fishing for?

      Shrimp is the primary fishery.

    2. How does Rocky, the biologist, determine the fish bought at a local market are bull sharks?

      He counts their teeth.

    3. Bull sharks spend most of their lives in the ocean. Why does Rocky think they migrate to freshwater habitats?

      Rocky thinks that bull sharks migrate to freshwater so females can give birth where they are safer from other sharks. He also says that rivers provide an environment that bull sharks are "good at dealing with, and other sharks just aren't."
