Stone Fish

Species - Synanceja trachynis, Synaneichthyes verrucosus

Description
The Stone Fish is a mottled brown-greenish in colour (which gives them camouflage) with many venomous spines along its back.

Habitat
The stonefish lives primarily above the tropic of Capricorn. Its main habitat is on coral reefs, near and about rocks, or can be found dormant in the mud or sand. It feeds on small fish and shrimps.

Venom
The sting causes excruciating pain and a great deal of swelling rapidly develops causing death to tissues. The severity of the symptoms depends on the depth of penetration and the number of spines penetrated. The symptoms of the venom are muscle weakness, temporary paralysis and shock, which may result in death if not treated.

Do not attempt to restrict the movement of the injected toxin. Bathing or immersing the stung area in hot water may be effective in reducing the pain. transport the patient to the nearest medical centre. Hospitalisation for intravenous narcotic analgesia, local anaesthetic infiltration or regional block may be required.

Definitive management consists of administration of stonefish antivenin. Indications for antivenin include severe pain, systemic symptoms or signs of (weakness, paralysis) and injection of a large amount of venom.

Note: For those having difficulties to recognize the fish, I did a WS to help you. Constrast may look a little soft in original picture, but that the way you see in water with some suspended sand, so I decided to present it as I saw it.

Technical data:

Camera : Nikkormat EL
Accessory-1 : Ikelite camera housing with dome port
Lens : 28mm f :2.0 Nikkor
F/stop : Not recorded
Shutter speed : Not recorded
Filter: close-up lens +2*
Flash : Vivitar 285
Accessory-2 : Ikelite flash housing
Film : Ektachrome 64
Flatbed Scanner: Epson 4180

* Close-up is necessary when the housing is used with a spherical dome port in front of a wide angle lens. The spherical dome when in contact with the water, it creates a negative lens. This negative lens creates a virtual image very close to the camera. Unless you have a macro wide angle lens, it is necessary to put a close-up lens so you can focus real close with the wide angle lens.

Hi Alain,

Beautiful capture and well done on the composition.
Your presentation is excellent.
Increasing the "Contrast," in Bright/contrast to about +11 to 14 will help enhance your image.

This is a fantastic shot Alain. I like it.
Stone fish - beautiful and interesting object. Good contrast. Natural, very nice exposed colours and the image is crystal clear.
Excellent work! Well done!
Regards, Krzysztof.

Salut Alain,

Je crois que nous avons ici LE champion du camouflage toutes catégories !!! Aucune chance qu'il se fasse bouffer par un autre poisson :-)
La photo est simplement géniale et le sujet très intéressant. Les couleurs des coraux sont assez vive également. Belle prestation !!!

Great shot of the really cool camoufaged stonefish. The mottle effect that this fish produces is just amazing. The lighting is well balanced on this nicely composed image. Paul :)

Nice work, good job of focusing through the tank glass.

Hi Alain,
Talk about blending into your surroundings! Beautiful colors, and excellent detail. A very interesting note with this great shot,
Scott

Hello Alain,

This is an excellent capture, with interesting and informative notes.

Have you added that grey matter in the center top? It doesn't seem to look as though it belongs there.

Thank you for sharing this comprehensive and well presented photo and ws.

Great shot Alain, I have also seen these in Hurghada, I appreciate how difficult underwater photography is, and it is definately not one of my strong points.
This shot is colourful, sharp and a very good capture.
Good note too!
Thanks for sharing.
Michael.

Oh, I see it now - the pink and cream stone is the fish!! Scary Alain. I hope I don't need your instructions!! Your WSs are great, very informative. Thank you - well done.

Superb image, well spotted. There are so many good images here in your red sea collection. Great stuff.

missing it over there so much... :-(

Hi Alain
These Stone Fish have taught me to never dive barefoot!! Watching a stung person suffer is horrible!!
