Today we’re looking at coral pictures (mostly). But first I want to tell you about the most beautiful screen saver on the planet. Understand, that’s just one man’s opinion. It developed as an homage to Philip K. Dick’s novel Do Androids Dream of Electric Sheep.  You can find it here. You have to sign up for an account, but there’s no money involved. It does require an Internet connection occasionally to give the full effect of evolvement, but it works fine without one. Here’s a screen shot of the home page. If you like to fool around with screen savers, give this one a shot.The electricsheep.org siteNow, on to the coral and whatever.

Wouldn’t you know that the first one up is a species that I can’t find. I tried Googling “cup coral” which is the obvious name for this, but I couldn’t find anything like it. My invertebrates book is of no help. If you know the genus and species of this thing, please leave a comment:Cup coral (species unknown)It is about six or seven centimetres in diameter.

I am pretty sure about the identification of this coral (Acropora cerealis): Coral (Acropora cerealis)It is one of the most common species here. It is very delicate. A brush of a fin can knock off a huge chunk.

This one is quite beautiful when the sun is shining down through the water. It is a species of the Montipora  genus:Coral (Montipora species)It has many tubeworms embedded in it. None of them came out to play.

This is another very pretty coral (Pachyseris speciosa).  Both this and the one above are massive. They are often over two metres across:Coral (Pachyseris speciosa)Sometimes what is growing on, in or near the coral is just as interesting. Here Sea Squirts (Atriolum robustum)  grow surrounded by Porites  coral:Sea Squirt (Atriolum robustum)Well, they obviously don’t grow on the coral, but on a bit of dead coral that is embedded in the Porites. 

I’m a bit of a fan of Sea Squirts. This one you’ve seen several times before. You can enter ‘molle’ in the search box to see previous posts. This one is Didemnum molle.  It has a nice coral, which I think is Goniastrea australensis  in the background:

Sea Squirt (Didemnum molle)The shading on the molle  is hard to get right.

Here’s another molle  with several species of coral in the background:

Sea Squirt (Didemnum molle)The molle  is about five centimetres across. You can also see a couple of Dascyllus reticulatus  in the background.

Did I mention that I’ve never been bored on a dive?
