This is seen during night dives on the outer islands of Malaysia. Night dives are not allowed in many places in Malaysia. There are only a few resorts on the outer islands in Semporna. Diving can be within the designated range. Many corals are actually fluorescent, and the fluorescence appears after playing the purple lamp, which is simply beautiful. The diving watch on my body, along with the manicure lamp with the fluorescence, is on. As in a dream, this is the charm of night dive. There are also rare lightning shells, salmon, etc. Night dive, in the process of teaching, the students' first reaction is to ask what can be seen in the night dive. In fact, many marine creatures do not come out during the day, and will not come out for food until the evening. Night dives we usually see hermit crabs, octopuses, various shrimps, if you go to Madai to see big sharks, etc. Night dives also have the advantage of not bringing flashlights during the day, but night dive flashlights are necessary. The sea will absorb the color, and the night dive is you will be surprised to find that everything looks so realistic and bright, completely different from what you see during the day, because the flashlight restores the original colorful color of the creature. I like night dives very much, I hope you can also love night dives.
