yes its very real... i took the picture twice as the small fish inside kept covering the eye bit..
PHP:

PHP:
 	Isnt that the singer from Kajagoogoo? Limahl or somebody?

hmm yeah maybe... but doesnt Limahl have two eyes?
 
Sands,
Are those from your local waters?? I have never looked inside 'em here...

these are all from Fujairah, in dubai we don't get this vis but we do get the fish... really only about 10 species of reef fish exist here now (thanks to the dreging of the Palms).. but there still are big shoals of pompano and barracuda.

Fujairah is a 2 hour drive from Dubai.. :)
 
the pompano I know about. Go out a bit and you will see Amberjacks (deep), large Kanad (King Mackeral), and various other members of the Trevally family. When lucky (especially right now) you will see "sicken" <cobia> in the 20-40KG range. Great if you have a totemsub :) ... but hang on for a ride
 
Schematically the top center of a sea urchin is something like this:

If this is not a common occurance then maybe it was upside down - the bottom side has it's mouth that is in a structure called 'Aristotle's Lantern' (anybody can tell us why?).
Maybe it looks like this only when the anus opens (or in heat or soemthing. ;)) or changes colors for some other behaviouristic reason. Maybe it lives in symbiosis with this fish and those colours are ment to attract it.
I've found another picture where you can see that there's something in the center but it's not as colourful as the picutre you posted:

Nothing that some spanking won't fix. :D

EDIT: Maybe that's the nature of this fish-urchin symbiosis!
 
Sara,
That looks a starfish wrapped around the sea urchin or sea urchins all bunched together, that's what I was going to say until I read Deepthought's comment that it could be an upsidedown urchin. Notice the white spots at the end of the "tentacles"? Very mysterious indeed!

Adrian
 
Adrian might be on to something, the brittle star family are known for having a circular center body. Maybe that is just one of their color paterns. :crutch
 
hi Sara,,,
that see urchine is very poppular in these waters,,,, make sure you dont bump into them as they are very poisonous and the needles very sharp and brittle .... i have had a few bumps in my life andi tell you it HURTS !!!!

I suppose that is an eye, i have tried touching these things with the but of my gun, they kind of can see the gun approach and they move thier needls in to defend them self,
 
Its a starfish wrapped around a dead sea urchin-no doubt about it.
The only funny thing is the "bright" eye in the center but then again we can just blame the camera flash for that...

i didn't use a flash... and the "eye" looked that before i filmed it... i see that there is maybe a brittle star within the urchin, perhaps he is eating it.

maybe Deep Thought's explanation is more logical :)
 
Aint a starfish, the pental (five) lines are the symetrical patterns of a seaurchin shell. SeaUrchins are of course echinoderms which often feature pental symetry. So do Starfish of course, being echindoerms also. BUT:

What you have there is a Diadema sp SeaUrchin... :)

Heres one we get in Oz.

ah right! now you can see it really clearly in that photo.

I should have realised that about the five symmetrical patterns of a seaurchin as often you find small white skeletons of them on the beach and they have those patterns imprinted on them.

That's great photo, did you take it?
 
Nope, that whole database is from David Harasti, a MarineBiologist who I have the honour of knowing. He's a very good photographer, and a great guy to boot. He helped me out a lot, and still does, with my photography.
