There are several types that I see. This one is a pebbled sea star. The other is a Ghardaqa sea star. Arabic does not follow the convention of “u” after ‘q” so it is disconcerting to type, especially names.
Nice. Cute. Solitary. Frequently found under coral. They aren’t too special to me since I have seen lots of starfish in the aquariums I have frequented. But I’m still having fun finding them during a dive.
Natural light does not make the background fade. It gives an overall tint of green with reds washed out. Digital white balance can compensate. Flash gives a more natural look. But then again, why are the animals red at all. At depth the natural color fades and red is not really seen. Or it is dull. So why then be red? There’s a question here somewhere. If you can’t see red are you invisible. Or, does sea life adapt anyway and not see red? Or are fish color blind? I’m not wiki so I will let you look this fun fact up.
