Female Great White Shark May Nagivate Using Stars as Visual Reference

South African and American scientists have tracked a female great white shark on her transoceanic journey of over 20,000 miles, proving that sharks travel the oceans between Australia and India.
Most intriguingly, scientist Ramon Bonfil noted that the shark, nicknamed "Nicole" (after Australian actress Nicole Kidman), spent about 2/3 of her journey very near the water's surface, suggesting that perhaps she used the visual stimuli of the stars to help her navigate.

I wonder if she has different names for the constellations than we do. Swimmy the Tasty School of Eels, for example, or Floaty the Yummy Wounded Surfer.
