Not far from the Cathedral dive site, I gave a quick glance at my diving buddy just to make sure that everything was ok. He was pointing his index finger at me, while moving it back and forth. You know, like a kid does when he is shooting at you with an imaginary gun. I quickly did a one eighty and saw it - not more than 10 meters away. Fat lips, prominent yellow and black dorsal and anal fins, maybe 60 centimeters in length.
