Titan Triggerfish are usually a bit wary of divers. The exception is during the nesting
season when they lay eggs. At that time they will chase you away from the nest and bite.
Notice they have large teeth. This was not nesting season, and I caught this fellow
by luck. This was taken with a Canon 5D, ISO-125, 16-35 mm lens, f/9.0 at a 1/160th.
I was very close for this wide angle shot. A little crop but no PS3.
Check out the eye.!
