fishoutawater:Hey Christi,
Doesn't Cozumel have its own population of Hammerheads?
I haven't been there since '91, but I distinctly remember my assigned dive buddy grabbing my fin to get my attention. He pointed towards the surface, I looked up, and there were about forty or fifty of them all swimming the same direction in a school formation. I wanted real bad to go up to them, but we were at about 90 feet, and they looked to be at the surface. I took a couple pictures with my cheapo Ikelite disposable camera housing, but they didn't come out at all.
Not to my knowledge. In the last five years there are only three reported sightings that I am aware of. These sightings were all single shark sightings, in 60ish feet if water around twilight time.
No offense at all intended, but to see schooling hammerheads in Cozumel at the surface would be a freak thing and a truly once in a lifetime experience.
Hammerheads like cooler/darker water for starters, so they are typically very deep. We had to go below 80 feet to see them in these numbers. We were also told that during dry season in Cocos, they move even deeper because the water is too warm for them at the "shallower" 80 to 100 foot depths.
I've never heard of any schooling sharks in Cozumel, let alone hammerheads.
