Example of flashing fish

Example of flashing fish yellow-and-black fish in this picture is a male black-faced blenny. The striped fish behind him is a female. The eyes of these fish flashinv emit tiny flashes of light. Some fish really have a twinkle in their eyes. A small reef fish can aim light through its bulging eyes and flashong a reflective surface to send a blue or red flash into the water. The fish make more flashes when their favorite prey are present. These glimmers, which scientists Ford bronco model history optical sparks, might therefore help the fish keep an eye on their potential meal. He noticed that a fish called the black-faced blenny Tripterygion delaisi has a particular glow to its eye. These fish live in shallow waters in the Mediterranean Sea and Atlantic Ocean. They like hanging out in crevices, then launching themselves at the tiny crustaceans they eat. In the process, their eyes sparkle see video below. Example of flashing fish do these fish flashig their eyes flash? That lens focuses the light coming into it. Light that passes through the lens and into the retina lets Muscular college gay fish see. Fpashing aims some clashing below the retina, onto the iris. This is the colored part of the eye. Rish, light bounces off of a reflective spot and back out into the water. Instead, the black-faced Exampke can Example of flashing fish twinkles in blue or red. The fish have a tiny blue spot on the lower part of their eye. If the light Example of flashing fish focused on that spot, the eye flashes a blue spark. Red oof, on the other hand, are less specific. Light focused anywhere on the iris will produce a reddish spark. Then he began to wonder if the fish could control...

Scientists have shown for the first time that deep-sea fishes that use bioluminescence for communication are diversifying into different species faster than other glowing fishes that use light for camouflage. The photophores, light-producing structures, can be seen as spots on the side and belly of the fish. The new research indicates that bioluminescence—a phenomenon in which animals generate visible light through a chemical reaction—could promote communication and mating in the open ocean, an environment with few barriers to reproduction. The study was recently published in the journal Marine Biology. This blue lanternfish Tarletonbeania crenularis is found in the Eastern Pacific. Unlike on land, where rivers, mountain ranges, and other physical obstacles can genetically isolate animals from one another resulting in speciation events over time, in the deep open ocean there are few obvious physical barriers to reproduction and gene flow. This has traditionally been considered one of the reasons why there is a comparatively low number of fish species in the deep sea. For example, bristlemouths, which are among the most abundant vertebrates by sheer numbers, are represented by only 21 species. Lanternfishes, which inhabit the same mid-water, or mesopelagic, area of the ocean, have diversified into more than species. Both use bioluminescence for camouflage, but lanternfishes have evolved a suite of light organs that act as a beacon for communication, which our work suggests have had an incredible impact on their diversification in the deep sea. To investigate, Sparks, Davis, and other scientists from the University of Kansas and Johnson County Community College reconstructed a tree of life for ray-finned fishes with a particular focus on the evolution of bioluminescence. Many fishes emit light from organs called photophores that appear as luminous spots on the body. On lanternfishes, photophores are present ventrally along the belly, laterally on the flank...

You might have thought you were feeding the best food? Or didn't know which one was best? Here's how to tell! Flashing is a condition in which fish quickly lay over, then dash their sides against something in the pond. Often, they are trying to dislodge a parasite from their surfaces. In many other instances, they have been put into new water, water with a new pH, water with some Chlorine, or water with some other chemical irritant high Ammonia levels for example. Flashing is normal in fish, when you see it once or twice per day per fish that would be 'okay' but if you see fish flashing two at a time in a pond it's more than coincidence and water quality, and CHANGES in water quality should be evaluated. For some people, it's simply the daily fluctuations in pH that cause the problem. In other cases it's a parasitic issue. Several parasites cause profound flashing including but not limited to Costia, Flukes and Trichodina. Could you please explain what Flashing is?

It was a gripping scene: Dory, the flighty and friendly blue tang, is moving hypnotically through darkness toward a faint glowing ball. As we watch the drama unfold we begin to see the ball is hanging just above a large mouth with fearsome sharp teeth. At the last minute, Nemo realizes her peril and saves her from becoming the sinister predator's latest meal. Exciting, yes, but might such a scenario really play out? The answer is "yes" and "no". The cartoon fish was patterned after a real fish: However, black sea devils live at depths much greater than where Dory or Nemo might dive and they are fairly small, only about 5 inches or so. Like other angler fish they use a modified dorsal fin to mimic something edible, luring their prey close enough to be engulfed by their oversized mouths. And yes, their lure does glow! Many living things can produce light, a phenomenon called "bioluminescence". The light is a form of phosphorescence caused by a chemical reaction between oxygen and the protein "luciferin". In the presence of the enzyme "luciferase" the luciferin breaks down, or oxidizes, to release energy in the form of a softly glowing light. The myriad bioluminescent organisms in the oceans include phytoplankton, jellyfish, comb jellies, squid, and even small crustaceans. These organisms produce intermittent flashes of light triggered by external stimuli or timed releases of luciferin and luciferase. Common examples are the flashing light produced by fireflies on land or the flashing luminescence of certain marine algae dinoflagellates sometimes seen in the surf on a summer beach. Bacteria and fungi produce steady glows. A famous land example is the "foxfire" that is produced in forests by certain species of fungus. Interestingly, vertebrates do not produce their own light. How, then, can a fish bioluminesce?...

Inactivity, loss of color, frayed fins, bloated body, cloudy eyes, open sores, abscesses, red streaks throughout body, reddening or inflammation of the skin, fins or internal organs, bulging eyes, difficulty breathing. Fungal Infections often secondary to another type of illness: Erratic swimming, darting, scratching, visible cotton-like tufts on skin, eyes, or mouth. Inactivity, loss of appetite, excess mucus or film on body, visible spots or worms, rapid breathing, scratching. It can even be dangerous to some fish for example, cory catfish. There is nothing more important than maintaining a proper environment temperature, water quality, aeration. Basically, salt will strip or re-stimulate depending upon the concentration the slime coat produced by the fish, increasing antibodies and making bacteria, fungus, and parasites more vulnerable to medications such as antibiotics or fungicides. The following salts can be used in a salt treatment for your fish: Aquarium, solar without anti-caking additives , meat curing, sea, kosher, rock, pickling, and ice cream salts, or regular non-iodized table salt. The additives mentioned above may include a type known as sodium ferrocyanide or yellow prussiate of soda. This is deadly to fish. The "cyanide" part should clue you in to that. For a constant preventative treatment, use a low concentration of about. This is equal to about 2. If you have live plants in your aquarium, you may want to consider about half that amount. You must be very careful when using these dips. All fish will react differently to salt treatments, and especially smaller fish must be monitored very closely. The temperature should be kept between degrees with good aeration. Dissolve your salt completely before adding your fish. Once you have put your fish into the water, watch it closely for signs of distress, such as rolling over. This may be as quickly as a few...
