This week's image is a 1:2 macro shot of a Nephthid soft coral (Dendronephthia sp.) These corals come in many colors, most much paler than this example. I took this photo several years ago at Bunaken Island, Indonesia.
Oh it's a coral, I thought it was the inside of a heart, lol ! I am influenced by CSI series ! My bronchitis is gone and I feel like a fish in water again, thanks !
Hmm, so far people have said it looks like the inside of a heart, pickled cauliflower, and a network of brain nerves. Any other first impressions? (It's soft coral -- really it is!)
I was listening to a radio program the other day about the decline of coral reefs due to increased acidity of the oceans (more CO2 in the atmosphere means more acidic water). Have you guys seen any evidence of that?
Bobbie, What did you do to light that shot? Anything special? It is beautiful! I am going to have to try to recreate that with some of the gorgonians found here in Florida. Here is my Decorator Crab.
I love coming to your site to see what underwater creature you are going to post for the weeks WW. As always great pic. the color is stunning. Happy WW! Kyla
Thanks to all of my Wordless Wednesday friends for visiting -- mostly while I was sleeping! It's still morning here in Hawaii.
@ Chris in Oxford - Acidification of the ocean is indeed a growing problem -- more and more evidence accumulates, not just degradation of the coral reefs, per se, but in things like an apparent effect on the shells of sea turtle eggs, and the shell quality of molluscs and some crustaceans (they're more fragile than they used to be) -- and who knows how many other more subtle things that we're not aware of yet.
We have witnessed some degradation of our local reefs over the period of years we have been visiting them. I can't say how much is attributed to a change in the pH of the ocean, because there are other factors, too - especially silting from runoff due to the loss of plants/trees in the coastal zone as a result of development. Likewise, development usually means introduction of chemicals,from lawn fertilizers to pesticides, which also destabilize the reef ecosystem. (Think rampant algae blooms that smother coral.) I could go on -- but I'll save it for a whole post one of these days.
@ Christopher Smart - According to the notes in my logbook, that photo was taken with a Nikonos 5, and a 35mm lens, using extension tubes to accomplish a 1:2 ratio. Aperture was f/16 -- so very little ambient light -- with a Nikon SB105 strobe set to 3/4 power, aimed at the subject from just above and to the right of the lens. The image was captured on Fuji Velvia slide film (ISO 50). The trick is to get in really, really close to fill the frame completely with the subject. With paler colored corals, I would have set the strobe to full power.
@ Robert - All of my marine life photos are taken in the water, while diving.
@ Kathy - Actually, when you see them from a distance, the true colors are not evident, due to the light filtering effects of the sea water. Red things often look dark brown or even black underwater. Only when you light them artificially and at relatively close range do you get to see and photograph the true colors.
The Right Blue refers to the goal of a lifelong pursuit. Sea water viewed from beneath the surface comes in many hues and shades. Surfers wait for the perfect wave; divers seek the right blue.
