[Note Guidelines] Photographer's Note
I have seen several blooms of orange jellyfish in the sea this year, enough to turn the sea orange, so It was good to see a single specimen on which to concentrate the camera lens.

Jellyfish live mainly in the ocean, but they aren't actually fish - they're plankton. These animals either float in the water or possess such limited swimming
powers that currents control their horizontal movements. A jellyfish of this size has some control over movement, and the 'bell' contracts and relaxes in a very interesting way.

They are mostly carnivorous and eat other animals. Smaller jellyfish eat algae and other tiny plankton called zooplankton. Larger jellyfish eat crustaceans and other bigger aquatic animals. They don't seek out people to attack - their nervous system is too simple to do that, but their sting is both a defense mechanism and a way to capture their prey.

Each jellyfish tentacle is covered with thousands of cells called cnidoblasts, which house nematocysts containing stinging threads. When a jellyfish encounters another object, pressure inside the nematocyst causes the threads to uncoil. The stinging cells spring out at the unwitting victim like tiny darts, firing venom into it. The venom is a neurotoxin designed to paralyze jellyfish prey. Although a jellyfish can kill a small aquatic animal, its sting is not usually fatal to humans, and one of the best treatments is vinegar. That's another item that maybe I ought to carry in the camera bag.

I think this may be a variety of Compass Jellyfish, but I need some ID help here.

I used a circular polariser in order to focus underwater, in this relatively shallow stretch of water between the islands of Moster°y and Kloster°y. I also darkened the background, and used 'spot treatment' to get rid of some distracting small bits of detritus in the water.

Very nice picture.
Great colours.

Hallo Amelia
Good shot! This shot has an almost ethereal quality to it, the yellow and white against the dark background and the almost spooky shape come together to create a wonderfully moody image. BUT a wonderful moody one indeed, with details beautifully seen. Thanks for sharing. Best regards.

Hello Amelia,

a great shot.
Very fine colours anaingst dark bg,it's like a spaceship in space.
I don't know the ID but the details are very good.
Well done Amelia, you learn very fast.

Hello Amelia,
a nice capture and an excellent composition of this creature. the colour contrast is splendid.
A well presented shot in intense colours.
The tentacles are stunning1


Dear Amelia,
I do not know anything about cameras- did you take this shot with an under water camera?

Like your sea shore photo - I only know Indian Ocean Sea Life - how big was this animal?

I see in the "photo info" that your flash did not fire; what is the light area underneath the fish / on the bottom?

I tried my hand in the Maldives on underwater photography and was totally unsuccessful!!

Your notes are very informative in the tradition of TrekNature...

I like the way you presented this image.

Have a nice evening
Warm Wishes

Ciao Amelia. Best compliments for this alternative one with fascinating light and bright colours. Bit noised in my opinion.

Hello Amelia,
I'm sorry to have overlooked some of your posts - you've made a very nice start here on TN! I love the underwater world and this is a superb capture of a beautiful jellyfish - very professional!! Details are so sharp and the orange/white colours against the dark water wonderful. I remember seeing lots of these off the coast of Denmark as a child.
TFS and best wishes, Ulla

Hello, Amelia - I would love to see one of these beautiful creatures 'dreaming' nearby - TFS from LTM
