NATURAL HISTORY MUSEUM - UNITED KINGDOM : ON SO MANY JELLYFISH : THEY ARE OLDER THAN THE DINOSAURS

NHM - UK : JELLY FISH 

I think jelly fish are so beautiful and - usually - graceful. This web site has some excellent photographs, illustrating the diversity of jelly fish beauty!

Excerpt: Jellyfish come in incredible shapes, colours and sizes. Most jellyfishes’ bell-shaped bodies are between two centimetres and 40 centimetres across. However, some species can grow to more than two metres in diameter, with thin trailing tentacles that are even longer than that.

Jellyfish have radial symmetry, meaning that if you sliced a jellyfish down the middle, the parts would be symmetrical, like the segments of an orange.

These cnidarians are famous for their stinging abilities. The intensity of the sting varies by species.

Some jellyfish can also generate their own light, called bioluminescence – further adding to their otherworldly beauty.

BLUE BIOLUMINESCENCE - INCOMING WAVES AT NIGHT NOW - LONG BEACH - SUNSET BEACH

PRESS TELEGRAM - WAVES GLOWING BLUE WITH BIOLUMINESCENCE  waves from San Diego to Oxnard - great photos!

Excerpt:

The bioluminescent waves are caused by a dinoflagellate algae that that turns the ocean red during the day, but glows when agitated at night. Though the presence of a red tide can give a clue to when the glowing algae may show up at night, but they are highly uynpredictable and touch to find as wind, currents, and

SEA PEN SHAPED LIKE A SAXAPHONE FOUND IN SYDNEY AUSTRALIA HARBOR - IT GLOWS WITH BIOLUMINESCENCE and is COVERED IN SLIME!

 Gotta see those photos!

DAILY MAIL : SEA PEN THAT LOOKS LIKE SAXAPHONE

Excerpt: Australian Museum's marine invertebrates head Professor Shane Ahyong confirmed what type of creature it was.

'They are relatively common in the eastern part of the harbour, well below the tideline, and so are sually only seen by snorkelers and divers,' Dr. Ahyong told Yahoo.

The sea pen in question had notable bumps on the bottom of it and a long stalk, with the way it was laid on cement in the photo closely resembling a saxophone's shape.

BIOLUMINESCENT ALGAE MAKES SWIMMING DOLPHINS GLOW


DAILY MAIL SCIENCE : SWIMMING DOLPHINS BIOLUMINESCENT GLOW

Excerpt: According to Mr. (Patrick) Coyne, the footage was challenging to film and required the perfect conditions - with bioluminescence being both difficult to spot and inherently short-lived in nature.

The glowing effect, often referred to as 'the fire of the sea', is produced by microscopic, single-celled organisms known as dinoflagellates, specifically those of the species Noctiluca scintillans.

A NEON LIGHT SHOW OF FISH! BIOFLOURESCENT!

LA TIMES SCIENCE : UNDERSEA LIGHT SHOW THE SECRET

"Scientists have discovered more than 180 species of biofluorescent fish that glow in neon shades of blue, red, orange and green -- most of them hiding out in tropical coral reefs.

Some of the fish glow just around their eyes. Others have intricate fluorescent patterns on their bellies or backs. And some of the fish glow all the way through their bodies. If you slice a false moray eel like a salami and shine a blue light on it, the entire cross-section would illuminate.

And it turns out that reef fish that are the most mottled and brown and difficult to see are the ones that tend to fluoresce the most."
