I made a spontaneous decision to go night diving last night at two places, one called Tijeretas and the other Caragua, a 90 year old sunken ship modeled similar to the Titanic.  I was desperately hoping to witness a small but controlled feeding frenzy of sharks, but unfortunately that didn't happen (there may have been sharks but our dive lights only permitted us to see 15 ft in the direction in which its pointed).  But there were tons of cool organisms that welcome the darkness of night to slither out of their daytime hiding spots.  There was only a handful of us diving, half of us working on dive certifications and the other half just for the thrill, and we got pretty lucky I'd say on the conditions:  26 degree Celsius water (although I was braced with a 5 mil on top of my dad's sharkskin & underarmor, but also brought gloves, hood, & spring suit to put on top of the 5 mil just in case), some wave action (but only noticeable at the surface), a little bit of current, and very little suspended sediment.  So we get in the water and we each turn on our lights, and somehow as the only person who hasn't done a night dive yet I naturally get the "stubby" light, aka the light that is barely kickin.  But whatever, I just used that as an excuse to get really close to everything like the 4ish sea turtles (green and black morphs), red eyed octopuses, an eagle ray, Pacific mutton hamlet, scrawled filefish, Panamic graysby, breeding Panamic sergeant majors (different from other b/c of their dark blue wash), a couple of timid mottled soapfishes, Panamic soldierfish, three banded butterflyfishes, a shit ton of Pacific creole fish, among others.  Also there's the sponges and ahermatypic corals that come out to feed like black corals, polychaete worms, and zooanthids but I focused more on the fish.  During this incredible dive me and my dive buddy (which also happened to be her birthday & lived with my mom and host family last semester, so my mom threw her a party earlier that day where we all gorged on wine, juice, and all sorts of vegetarian goodies (we're both vegetarians), and lots of cake & sweets; only to be followed by hanging outside the house nursing our full bellies and filling the air w/ our laughing) separated some from the group & turned off our lights.  We found ourselves floating in a sea of stars, lights dazzling all around us.  This light is from the tiny creatures that migrate up from the depths at night emitting a self-produced light called biological luminescence, or bioluminescence for short.  Drifting all around us, they dotted our outlines allowing us to be temporary constellations in the sea.  With every movement, a new constellation.  Not wanting to get to far from the group in the pitch blackness and after sharing this experience, we rejoined the others and could now cross this off our bucket lists.  The rest of the dive was just as enlightening and while I'd like to write more, I have to go pack for my boat which leaves in an hour.
