We've been diving in the afternoons this week, when Amy gets back from the hospital. We've seen some more sea turtles and some squid (among other things). We started our advanced open water course with underwater navigation (using a compass underwater) and tonight we did a night dive, which was awesome. The boat goes out at sunset, so its still a little light when you get in the water. We saw some big fish, including a huge file fish, and lobster, sea urchins and even an octopus (definitely the highlight). After swimming around for awhile, we all sat in a sandy patch and turned off our lights for a few minutes. You could see the phosphorescence like sparks in the water--it was pretty cool.
