Many longtime sailors have been mesmerized by the dazzling displays of green light often seen below the ocean surface in tropical seas. Now researchers at Scripps Institution of Oceanography at UC San Diego have uncovered key clues about the bioluminescent worms that produce the green glow and the biological mechanisms behind their light production.Marine fireworms use bioluminescence to attract suitors in an undersea mating ritual. Research conducted by Scripps marine biologists Dimitri...

The phenomenon of light emission by living organisms, bioluminescence, is quite common, especially in marine species. It is known that light is generated by chemical reactions in which oxygen molecules play an important part. In the animal world, these chemical reactions take place in special luminescent cells called photocytes. These are aggregated into complex light organs, in which the intensity of light is regulated by nerve impulses, and in which light can be modulated with the help of...

The ocean is deep, dark, and murky but with the help of mirrors a fish in the Pacific gets along just fine. Scientists from Tuebingen University, Germany, discovered a rare, living brownsnout spookfish, Dolichopteryx longipes, last year off the coast of Tonga. They found that it was the first vertebrate ever found to use mirrors, rather than lenses, to focus light in its eyes.Professor Julian Partridge from the University of Bristol, said, "In nearly 500 million years of vertebrate...

By Simon Usborne It was a journey to the bottom of the Gulf of Maine in 2005 that inspired Claire Nouvian to put together an unprecedented showcase of creatures from the bottom of our seas. Plunging down 1,000 metres in a pressurised submersible, she calls the experience the "most incredible moment" of her life. "It was so beautiful and so intense, it changed me for ever." Two years on, the French wildlife journalist and film director has amassed a gallery of mesmerising finned octopuses,...

Despite having to evade hurricane Katrina, a team of scientists from Harbor Branch and other institutions is returning to port this Sunday with new tales from the deep after completing their second annual Deep Scope expedition. The group has discovered a mysterious visual capability in a deep-sea crab; captured new video of a large, recently discovered squid species; and took clear video of the world's first known fluorescent shark. The Commerce Department's National Oceanic and Atmospheric...

Aug. 9, 2005 "” Scientists have used a glowing protein from fireflies to observe the activity of a molecule that is an important target for new drugs to treat cancer, autoimmune diseases and several other disorders. The target molecule, known as IKK (for IKappa kinase), regulates processes that can trigger dramatic changes in cellular physiology. Scientists have linked these changes to many different disorders. "Our new system allows researchers to monitor whether drugs for these...

MOSS LANDING -- As successful fishermen know, if you want to catch fish, you have to use the right bait or lure. This is true even in the deep sea, where scientists recently discovered a new species of jelly that attracts fish by wiggling hundreds of glowing red lures. This is the first time any marine invertebrate has been found to use a bioluminescent lure or to display red bioluminescence. This discovery is described in an article written by Steven Haddock of the Monterey Bay Aquarium...

WASHINGTON -- The first deep sea red-light district - glowing appendages on a newly discovered jellyfish relative - appear to flash their come-hither message to lure prey. Jellyfish and other types of sea creatures are known to produce light, but this is the first deep ocean invertebrate known to use red fluorescent light, said Steven H. D. Haddock of the Monterey Bay Aquarium Research Institute in Moss Landing, Calif. Three of the animals were found by scientists using a remote controlled...

It took only a minute for scientists to discover a new deep-sea species with an experimental infrared camera built in Southern California and light-emitting artificial lure. Now, the National Science Foundation has agreed to spend $500,000 to refine the concept developed by the Harbor Branch Oceanographic Institute in Fort Pierce. A large, 6-foot squid of a type never before photographed attacked the bait, a bioluminescent electronic "jellyfish," about 60 seconds after it was turned on in...

Humpback Anglerfish, Melanocetus johnsonii
2013-10-09 11:29:50

The Humpback Anglerfish (Melanocetus johnsonii), or common black devil, is a deep-sea anglerfish belonging to the family Melanocetidae, found in tropical to temperate portions of all oceans at depths of up to 6,600 feet. Male humpback angler fish are much smaller in size compared to the females, being no more than 3 centimeters long, whereas the female usually achieves a length of 7 inches long. Humpback angler fish remain free swimming into adulthood, which isn’t the case with other...

Bathocyroe fosteri is a species of lobate ctenophore found in all oceans around the world. It is typically found at intermediate depths and is very abundant near the Mid-Atlantic Ridge. This deep-sea comb jelly is named for Alvin (DSV-2) pilot Dudley Foster, who is credited with first collecting the specimens. This specimen measures about two inches tall and is bioluminescent. This species, as well as other ctenophores, reproduce sexually, with little to know self-fertilization known....

Angler, Lophius piscatorius
2012-04-02 16:12:16

The Angler, (Lophius piscatorius), also known as the Fishing-frog, Frog-fish, or Sea-devil, is a species of monkfish in the family Lophiidae. It is found in coastal waters of the northeast Atlantic, from the Barents Sea to the Strait of Gibraltar, the Mediterranean and the Black Sea. This species comprises a significant commercial fishery in parts of its range. The Angler has a very large, broad head that is flat and depressed. The rest of the body appears to be a mere appendage. The wide...

Double anglers are a family, Diceratiidae, of anglerfish. They are found in deep, lightless waters of the Atlantic, Indian and western Pacific Oceans. They are easily distinguished from other anglerfish by their possession of a second light-bearing dorsal fin spine immediately behind the illicium (the bioluminescent lure present in other anglerfish). As in other anglerfish, males are very much smaller than the females and, after a larval and adolescent free-living stage, spend the rest...

The Cookiecutter shark, Isistius brasiliensis, also known as the cigar shark or luminous shark, is a small rarely-seen dogfish shark. Anatomy and morphology The Cookiecutter sharks often glow green and grow up to 20 in (50 cm) long. The underside of the shark is bioluminescent, glowing a pale blue-green that matches the background light from the ocean's surface that serves as camouflage to creatures beneath it. However, a small non-luminescent patch appears black deceiving the shark's...
