fish real moon is the first to discover that totally has hot blood , like mammals or birds, which gives it a competitive advantage in the cold ocean depths, according to a study the National Oceanic and Atmospheric Administration (NOAA) of the United States.
The mammals and birds usually keep warm blood, but the real moon is the first fish that is being able to keep his whole body hotter than the surrounding environment.
fish that inhabit the same deepwater real moon they tend to be slow and lazy and to conserve energy ambushing prey their prey instead of chasing them.
However, in the case of sunfish their constant flapping warms your body, it increases your metabolism, their movement and their ability to react, according to a study published by “Science” .
This fish, about the size of a large car tire, is in all the oceans and lives hundreds of feet below the surface in cold water and in low light . It is also characterized by swimming through rapid flapping their pectoral fins as if they were wings.
Having the bleed hot makes sunfish a predator high performance fast around, react more quickly and view is more acute, according to Nicholas Wegner fisheries biologist at the National Oceanic and Atmospheric Administration (NOAA) of the United States in La Jolla (California), lead author of the study.
“Before this discovery I had the impression that this was a slow-moving fish, as most fish in cold environments, “but the fact that it can warm your blood making it a very active predator chasing agile prey such as squid and can migrate over long distances, “he said.
Wegner began to realize that the real moon was an unusual fish when study co-author, biologist Owyn Snodgrass, took a sample of gill tissue.
The hot blood vessels that carry blood into the surrounding tissue gill carrying cold blood back into the body after absorbing oxygen from the water.
engineering design is known as “countercurrent heat exchange,” which in the sunfish assumed that the hot blood from the center of the body helps warm the cold blood returning from the respiratory surface of gills.
It is similar to a car radiator and is a natural fit for warmth. Besides the unique location of heat exchange in the gills allows almost all the animal’s body temperature remains high even in cold water, which is known as endothermic, the study found.
“Never before had “seen anything like the gills of a fish is a” great for these animals that gives them a competitive edge innovation, “said the expert, who noted that” the concept of heat exchange in counter was invented in the fish long before us to think on it. “
Researchers collected data on the temperature of specimens of fish real moon in the West Coast and discovered that her body temperature was normally higher than the water around them.
In addition to temperature gauges coupled specimens of fish and followed in their dives hundreds of feet, after which he found that his body temperature was steady yet when the water temperature descended sharply.
The sunfish real has a muscle temperature is on average five degrees higher than the water that surrounds when nothing between 150 and 1,000 feet below the surface.
