The Australasian Gannet (Morus serrator) colony on Popes Eye Marine reserve is one of the only known human made structure that hosts yearly breeding birds. I took this photo while freediving and was lucky to capture the ducking of its head underwater to curiously check on the intruder. Gannet eyes can see exceptionally well above and below the water by changing the shape of its lens - allowing it keep its focus on the prey, or in this case the odd creature with the camera.
