Jelly Cloud
by Thomas Vignaud
I was freediving with my camera, around a island, when I suddently saw a big yellow gellyfish (Cotylorhiza tuberculata). When I came closer, I saw a school of juveniles fish, probably Trachurus trachurus, who were staying close to the gellyfish to escape predators. After a few shots, I started to place my external strobe behind the jellyfish : I had few nice results with orange lightning, and this one is the best.
Equipment: Canon EOS 400D and Canon 60mm macro USM

Just keep on giving this a visual feast Thomas. But again I ask you (Pl. do venture an answer) – Why is the sea so colourful when there is so little light beyond a few meters beneath the surface?!
Rasmus
Great photo with beautiful light using your flASH through the jellyfish.
Can you put your camera in some sort of waterproof container?
Thomas Vignaud
Hi and thanks
Anurag, as I said in the comment of the photo, I use an external strobe : it give the true color of the things back. things ARE colored, but the light is absorb by the water, especially red/orange, so we see it with blue/green dominant.

Yes I know that, What I ment to ask was that as a marine biologist, why does marine life display such warm red yellow colors when most of the light available is blue. warm colors would appear black in the available light. So what use do these colors would have. Evolution should have just(de)selected them out!

This is a really interesting picture.

Anurag,
ok, I understand what did you ask now
colors usually comes from chemicals of what animals eat (if you change alimentation of some species, they change the colors. some anelids have”feathers” who are white at the bigning (one kind of alimentation) and orange on the second part (another kind of alimentation)
or genetic factor.
so, even if evolution don’t selected colors, there is colors (who can be useless).
Underwater, there is always some light. even deeper than -300m, shrimps are super red : it is an evolution selection, because shrimps have the colors who is not where they leave. so, they become invisible, exept if you have a red light. so, some fish can really make red light (as a car at night) to find shrimps.
anyway, there is enought light where people dive, and it is sometimes very usefull : fish really know it’s a bad idea to eat a nudibranch, who is full of colors.
It can be a sexual attraction (usually on fish, like Thalasoma pavo), a repelent(like nudibranch), something to atract another specie as a prey or a helper.
but, as I said, sometimes it’s just useless. some fish are becoming red when they have to swim a lot, and so it help to know is there is strong current
It is very complex, and colors definitivly have a very important role, as odors, sounds, and more humans can’t feel !

Thanks Thomas!!
