[Note Guidelines] Photographer's Note
The Australian or White-spotted Jellyfish (Phyllorhiza punctata ) is native to the southwestern Pacific, though through unintentional introductions it can also be found in Hawaii, the Caribbean and Gulf of Mexico. Introduction to these other waters is thought to have happened through budding polyps which may have attached themselves to ships, or it could have been carried in a ship's ballast tank. As an invasive species, it has become a threat to several species of shrimp.

The bell of this large jellyfish is normally between 16-19 cm, though it can be found as large as 60 cm., where there are few predators and good food supply. It is typically bluish-brown with many evenly distributed opaque white spots, even down to the ends of the tentacles. I expect much of the colouring comes from its environment. It has eight thick transparent branching oral arms which terminate with large brown bundles of stinging cells. From each oral arm hangs a longer ribbon-like transparent appendage. They have only a mild venom and are not considered a threat to humans.

These jellyfish are typically found swimming near the surface in the murky waters near estuaries or in harbours. They are said to be very common during the summer months in New South Wales coastal waters and estuaries. I have seen these quite a bit while kayaking around Sydney Harbour.

This particular one was seen while I was strolling around Iron Cove (a bay on the south-west side of Sydney Harbour). I would estimate its size at roughly 20 cm. I have a shot of another one as well which was left stranded by the tide. This is in the workshop. The one in the workshop I lifted and placed back in the water with a couple of sticks after I took my shot. I would estimate its weight at about 1 kg, the bell has a consistency similar to silicone. It was still pulsing when I left, so I might have been on time.

Hi John,
Very good capture of this jellyfish!
You got very clear details on it, despite the picture was taken to the water.
It's very interesting the theory about how it can reach the Caribbean, being native from Australia.
Well done and thanks for share it.
My best regards,
JM

hi John,
bonne image, les méduses sont quelque chose de rare à Paris :).
Il y a un peu de bruit mais les détails sont conservés, la couleur également.

Hi John

Slight sharpening needed, but with the movement and water that may have been impossible, so excellent 'live' capture.

Hello John,
Great capture with excellent color and good detail, I have had the wonderful experience of a jellyfish sting along with my wife. Thanks for sharing John.

Hi John. Very clear shot of this large looking jelly fish. It is more scary than the see-through ones seen sometimes. Excellent clours and cropped for maximum effect. TFS. Murray.

I enjoyed your excellent presentation of the jellyfish (one that I have not seen in person). I, too like the range of colors and the hint of motion that does not compromise detail. Thanks.

John I often wondered why these jellyfish end up on beaches... just like beached whales... Seems strange they would not know enough to stay clear. But c'est la vie
< oops le mort > eh!

I like looking at them AND avoiding their sting! Tfs, Jay

Hi John,
nice shot of this jelly fish, shooting through the water is a bit tricky but you did very well and the details are nice and clear.
Very well done.
Sky

Good sharpness here on this jelly, which I've also seen on occasion in Sydney harbour.
Good composition and note.
Chris

Wow, those Aussie jellyfish are awesome aren't they ?
Not an easy shot to take by the looks of it, but you have done well.
Good work John.
Cheers,Steve

Hi John
Great note on this White Spotted Jellyfish. Brings back a few memories of being stung when I lived in PEI as a child...ouch. It's like being slapped when your freezing cold is how I remember it.

Nicely captured and sharp detail and colour.
