Sliteye Shark

• For the first time ever, scientists have recorded the sliteye shark in the Great Chagos Bank, part of the Indian Ocean.

  This is significant because:

  • The Great Chagos Bank is the world’s largest coral atoll (a ring-shaped reef or island formed of coral).

    It highlights the ecological importance of this region and suggests that the sliteye shark's habitat may be broader than previously known.
