fish real moon is the first to discover that has totally hot blood , such as mammals or birds , giving it a competitive advantage in the cold ocean depths, a study of the National Oceanic and Atmospheric Administration (NOAA) of the United States.
Mammals and birds tend to keep warm blood, but the real moon is the first fish that is being able to keep his whole body warmer than the surrounding environment.
The fish that inhabit them deepwater real moon tend to be slow and lazy and conserve your energy hunt ambushing their prey instead of chasing.
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 found in all 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 warm blood makes a predator sunfish high performance fast around, react more quickly and your vision is most 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 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 the squid and it can migrate over long distances, “he added.
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 blood vessels that carry warm blood inside the gill tissue surrounding the nerve leading back into the body after absorbing the water oxygen .
This 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 it allows almost all the animal’s body temperature remains high even in cold water, which is known as endothermic, the study found.
“Never before,” he 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 exchange countercurrent heat was invented in fish long before us to think on it. ”
The researchers collected data on the temperature of specimens of fish real moon in the West Coast and found that his body temperature was usually higher than the water around them.
They also temperature gauges coupled to copies of the fish and followed in their dives hundreds of feet, after which he found that his body temperature was stable even when the water temperature descended sharply.
The fish has a real moon muscle temperature is on average five degrees higher than the water that surrounds him as anything between 150 and a thousand feet below the surface.
