hahaha..you on fire today.
no lights, only sunlight. not deep here, yesterday only about 1and a half mtrs.
i have swam with the manta rays, biggies, in western australia. only sharks i have seen, luckily, are the reef sharks, harmless..fingers crossed.
when you have the tanks it is called diving. we just have snorkel and mask. my friend uses fins (flippers) going again today in about an hour.
i wrecked my underwater camera. got water in it, my fault. that was a sad moment. i mourned my camera.
