Let me revise: I keep thinking I've seen most of the underwater
critters that island has to offer. As for SR, that's always been one
of my favourite spots, but I'll admit I rarely dive it below about 80
feet - and no, have never tempted the abyss there.

No. Have done some shore diving around the caleta, but not the
river. Also, avoid the area around Chankanaab Park like the plague.
So I guess there's some more wildlife that I haven't seen. What's
that dive like?
Two DMs saw dolphins one day, one at the surface, and one at about
60'. So there's even MORE that I haven't seen.
I need to go back.

I've dove it down to around 180 and the visibility was good enough
that I could probably still see past 300... From what I could tell
(and remember) from probably 150 down, there doesn't appear to be much
of a change in the type of terrain... Probably a 50 degree or so slope
leading gently off into the abyss... Considering the fact that during
the last Ice Age, the waters were about 390 ft lower than these days,
there might be an ancient shoreline down there somewhere that could
have something interesting... There's actually a project going on now
south of Texas looking at this...

I've been in the cavern area, but I didn't have a line with me at the
time, plus no wetsuit, nor a light, so I chose to not go any
further... In my younger days, I wouldn't have let that stop me... I
have to wonder if I'm either getting smarter or just starting to
realize that Darwin isn't always going to be asleep on the job...
The halocline screws up visibility enough that you won't notice what
might be around you until you come face to face with a 5 ft
barracuda...
"Gee Grandma, what *big* teeth you have..."
I'm going to have to give it a try again the next time I get down
there...

You don't suppose that, just maybe, 150 to 180 foot depths have something to
do with that?

No... The place where the underground river meets the coast is fairly
shallow... I doubt that it is more than 20-30 ft deep at that point...
It's just that the mixing of the fresh and salt water create an
optical effect that while the water is clear, you can't see very
far... Kind of like mixing clear oil with water and shaking it up
vigorously...
