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.
