Barracuda Point Peculiarities

We had a very nice dive on Barracuda Point on Saturday. It’s near Pig Island  only a few Minutes from Madang. This is the sight at the east end of the point at only about ten metres:

That is a nearly solid wall of Pickhandle Barracuda (Sphyraena jello)  mixed in with a few Big-eye Trevally and one lonely Red Emperor.  You can see some more barracuda images here and here.

Down deep at about forty metres I got this shot of a strange red coral that I’ve seen before, but can’t identify. I’m assuming that it’s a coral. It is extremely red – about the only red thing that you can see at that depth, since most red light has been scattered by the sea water – and hard as glass:

Strange red coral?

The extreme hardness of the thing is surprising, because it looks as if it is very soft, like flower petals. The first time I touched one (not supposed to do that anyway) I got a little green blood leaking out of my finger – blood looks green underwater if you are deep enough.

I found this favourite of our starfish (Choriaster granulatus)  much deeper than it would normally be. I don’t know what it was doing way down there. They are usually not found below about 25 metres:

Pascal Michon, our resident Frenchman, is forever finding stuff on the bottom. He once found a Hewlett-Packard calculator on the reef. This time it was an old mask that had been there for quite a while:

Barracuda Point is surrounded by beautiful Sea Fan clusters. This one a a species of Melithaea:

This is a Barrel Sponge growing under a ledge. I’ve seen this several times before. They are always very pale instead of rich brown, the normal colour. At first I thought that it was just the lack of light that causes the paleness, but now I think that this may be a species that is not (according to my references) supposed to be in PNG waters. It should be around the Philippine Islands.  I think that it is Xestospongia testudinaria,  as if anybody cares:

At the bottom of the image, you can see a small Cleaner Wrasse swimming past. It’s a little blurred because of the long exposure time.

Back up in the shallows again there was a mob of Big-eye Trevally (Caranx sexfasciatus)  there to greet us:

You can see more Big-eyes here and here.

I’ll have a few more shots of the dive in a day or two. I’m still getting caught up from our drive up to the highlands. My hands are nearly back to normal now. After ten hours of gripping a wildly vibrating steering wheel, it takes me a couple of days to get over the numbness.

My brain feels a little numb too. Must have been the altitude.
