A group of scientists discovered that a tiny fish that inhabits tropical areas, and is very popular among aquarium buffs, possesses a chemically unique poison .
This is the blénido fanged ( fang blenny ) who use this compound to numb the jaw from predators once they are swallowed and thus escape unhurt.
According to Science Alert , these animals bite with their lower canines to secrete the fluid that was studied 40 years ago by zoologist George Losey, who tested it in mice and in himself no trace of pain .
These analyzes were further refined by a study by biologists from the University of Queensland who have discovered that among the compounds of this curious poison there are opioid hormones .
According to Brian Fry, one of the leaders of the research, the Scimex site : “The poison is chemically unique, the fish injects these compounds with other fish that act as heroin or morphine , inhibiting pain instead of causing it “.
“This is one of the most in-depth studies of how venom functions in any particular group of fish,” said Matthew Davis, an assistant professor of biology at St. Cloud State University in Minnesota, who did not participate in the research.
This discovery opens up a whole field for medical science , who are already talking about alternatives to current painkillers or protective drugs for strokes.
In the wild, there are about 2,500 poisonous fish registered , who throw the poison through the spines of their fins, tails or back.
