There are some pretty amazing things you find. So far there are some things I have been unable to identify. I keep trying and eventually I may be enlightened. This is a shy plant(?) which is seen sticking out of the coral. It retracts and is completely hidden whenever there is a threat. You have to swim up slowly in order to get a shot.
As an aside the Red Sea is so named because of the red coral. It doesn’t seem so red because underwater the first color that is lost as you go deep is the color red. But at night with a flash and restoration of the natural colors, I cannot understand the naming of the Red Sea.
This other object is or maybe a nudibranch or not. It is something I’ve only seen at night and it is certainly hidden under the coral. But I’ve looked during the day and you don’t see this. It’s tiny, pretty, and so delicate looking.
