• Be Supported
  • by Professor Nathan who researches the predatory the sharks can see.
  • by the West Australian State Government.
• Three Key Things
  • Mapped the physical characteristics of the eyes of the main predatory sharks.
  • To understand using complex computer modeling what that eye can see at different conditions.
    • ❓ patterns and shapes
      • present the wearer as hidden or hard to make out in the water
      • provide the greatest contrast but provide the greatest breakup of profile
  • Covert into wetsuits people might actually wear.
